Emergency and Acute Medicine: Cervical Spine Injury (Adult)
Cervical spine injury refers to trauma involving the vertebrae, spinal cord, or supporting ligaments of the neck, and may result from one or multiple mechanisms acting simultaneously. These injuries range from stable fractures to highly unstable patterns associated with spinal cord damage. Common mechanisms include flexion, extension, rotation, and axial loading forces, each producing characteristic injury patterns. Flexion injuries may cause wedge fractures, ligamentous disruption, or severe unstable injuries such as flexion teardrop fractures and bilateral facet dislocations. Extension injuries can result in fractures of the posterior elements, including the atlas or axis, and classic injuries such as the hangman fracture. Axial loading may lead to burst fractures or Jefferson fractures of C1, both of which can be highly unstable.
Blunt trauma is the leading cause of cervical spine injuries, with motor vehicle accidents accounting for the majority, followed by falls and sports-related injuries. Patients with pre-existing spinal conditions such as ankylosing spondylitis, osteoporosis, or metastatic disease are particularly vulnerable, as even minor trauma can result in significant injury. Penetrating trauma may also cause cervical spine damage, especially when associated with neurologic deficits.
Patients typically present with neck pain and tenderness, often accompanied by neurologic symptoms such as numbness, weakness, or paresthesias in the upper or lower extremities. However, a cervical spine injury must be assumed in any trauma patient with altered mental status, intoxication, inability to communicate, distracting injuries, or significant head and neck trauma, even in the absence of pain. Physical examination should include careful inspection for deformity or bruising, palpation of the cervical spine, and a thorough neurologic assessment of motor, sensory, and reflex function. Associated incomplete spinal cord syndromes such as anterior cord, Brown-Séquard, or central cord syndromes may be present and should be recognized.
Evaluation requires a complete clinical assessment combined with appropriate imaging. Standard imaging traditionally includes three-view cervical spine radiographs (lateral, anteroposterior, and odontoid views), ensuring visualization from C1 to T1. However, CT scanning has become the preferred initial imaging modality, especially in high-risk or obtunded patients, due to its superior sensitivity for detecting fractures and alignment abnormalities. MRI is indicated in patients with neurologic deficits, suspected ligamentous injury, or persistent symptoms despite normal CT, as it is the best modality for evaluating spinal cord and soft tissue injury. Flexion–extension views may be used selectively in alert patients with persistent pain to assess ligamentous stability.
Clinical decision tools such as the NEXUS criteria can help determine which patients require imaging. Patients who are alert, not intoxicated, without midline cervical tenderness, neurologic deficits, or distracting injuries may be safely cleared clinically without imaging. However, strict adherence to all criteria is essential to avoid missed injuries.
Initial management begins with strict spinal immobilization using a rigid cervical collar, backboard, and supportive padding. Airway management must be performed with in-line spinal stabilization, typically using rapid sequence intubation, with alternative airway techniques available if needed. Intravenous access should be established, and circulation supported. In cases of hypotension, clinicians must differentiate between hypovolemic shock and neurogenic shock, the latter characterized by hypotension with bradycardia due to loss of sympathetic tone.
In the emergency department, patients should be evaluated for associated injuries, as cervical spine trauma often occurs in the context of multisystem trauma. If imaging reveals fractures, dislocations, or instability, or if neurologic deficits are present, urgent consultation with neurosurgery or orthopedic spine specialists is required. Patients with persistent pain despite normal imaging may require further evaluation with MRI or dynamic studies. Historically, high-dose corticosteroids such as methylprednisolone were used in spinal cord injury, but current evidence does not support routine use, and their role remains controversial.
All patients with confirmed cervical spine fractures, dislocations, or neurologic deficits require hospital admission, often to an intensive care or monitored setting. Stable injuries without neurologic compromise may still require admission for observation and specialist management. Patients with minor soft tissue injuries such as whiplash and normal imaging may be discharged with appropriate follow-up and instructions to return if symptoms worsen.
A key pitfall is underestimating injury severity, particularly in patients with underlying spinal disease, where seemingly minor trauma can result in significant instability or cord injury. Strict application of clinical decision rules and a high index of suspicion are essential. Careful neurologic assessment, appropriate imaging, and early specialist involvement are critical to optimizing outcomes and preventing long-term disability.

Emergency and Acute Medicine: Sternoclavicular Joint Injury
The sternoclavicular joint (SCJ) is the only articulation connecting the upper limb to the axial skeleton, making it a critical but relatively uncommon site of injury. Stability of this joint depends largely on surrounding ligaments, including the anterior and posterior sternoclavicular ligaments, interclavicular ligament, and costoclavicular ligament. Injuries to the SCJ are rare and typically result from high-energy trauma such as motor vehicle collisions or athletic impacts. They may present as sprains, subluxations, or complete dislocations.
SCJ injuries occur when ligamentous structures are stressed or disrupted. In sprains, the joint capsule remains intact, while subluxation involves partial ligament rupture with preserved costoclavicular support. Complete ligament disruption leads to dislocation, which may be anterior or posterior depending on the direction of force and shoulder position at the time of injury. Anterior dislocations are far more common, accounting for over 90% of cases, and typically result from a posteriorly directed force to the shoulder. Posterior dislocations are less common but far more dangerous, often resulting from direct trauma to the medial clavicle or force transmitted through the shoulder. These can compress vital mediastinal structures, including the trachea, esophagus, and major vessels, making them surgical emergencies.
Patients usually present with localized pain and swelling over the medial clavicle, often holding the affected arm across the chest. Movement of the shoulder is limited, particularly abduction and external rotation. In anterior dislocations, the medial clavicle is visibly prominent and palpable. Posterior dislocations may be more difficult to detect due to swelling but may present with concerning symptoms such as difficulty breathing or swallowing, hoarseness, or signs of vascular compromise. A thorough neurovascular and airway assessment is essential in all suspected cases.
Diagnosis can be challenging with plain radiographs, as the SCJ is poorly visualized. Chest x-rays may appear normal, so a high index of suspicion is required. CT scanning is the imaging modality of choice, as it clearly defines the position of the clavicle and can identify associated injuries to surrounding structures. Ultrasound may be useful in the emergency setting, particularly in unstable patients, while MRI can provide additional detail regarding soft tissue and ligamentous injuries.
Management depends on the severity and type of injury. Sprains and subluxations are typically treated conservatively with rest, analgesia, and sling immobilization. Anterior dislocations may be reduced in the emergency department using traction and positioning techniques under procedural sedation, though recurrence is common and residual deformity is usually cosmetic. Posterior dislocations, however, require urgent reduction—preferably in the operating room with orthopedic and thoracic surgical support due to the risk of life-threatening complications. In emergencies where airway or vascular compromise is present and surgical support is unavailable, reduction may need to be attempted in the ED.
Patients with posterior dislocations or associated complications require hospital admission for monitoring and further management. Those with uncomplicated anterior dislocations or minor injuries may be discharged with appropriate immobilization and close orthopedic follow-up. Activity restriction is important during recovery, and high-risk activities should be avoided for several months.
A key pitfall is missing posterior dislocations, which may be mistaken for anterior injuries due to swelling. In children, injuries to the growth plate can mimic SCJ dislocations. Because of the potential for severe complications, especially with posterior dislocations, early recognition and specialist involvement are critical for optimal outcomes.

Emergency and Acute Medicine: Pediatric Cervical Spine Injury
Pediatric cervical spine injury is relatively uncommon, occurring in only about 1–2% of children with severe blunt trauma, but it carries significant risk due to unique anatomical and biomechanical features. Younger children, particularly those under 8 years of age, are more prone to upper cervical spine injuries (C1–C3) because of a higher spinal fulcrum, proportionally larger head size, weaker neck musculature, ligamentous laxity, and immature vertebral structures. In contrast, older children tend to sustain lower cervical spine and more diffuse injuries, including vertebral fractures. Certain congenital or syndromic conditions—such as Down syndrome and other skeletal disorders—further increase susceptibility to instability and injury.
A distinct feature of pediatric trauma is spinal cord injury without radiographic abnormality (SCIWORA), which occurs more frequently in younger children. In this condition, children may present with clear neurologic deficits despite normal initial imaging. Symptoms may include spinal shock, weakness, or sensory disturbances, and importantly, these symptoms may be transient or delayed, sometimes appearing hours to days after the injury.
The most common causes of pediatric cervical spine injury vary with age. In neonates, birth-related trauma such as breech delivery may be responsible. In younger children, motor vehicle collisions and falls predominate, while in older children and adolescents, sports-related injuries become more common. Clinically, patients may present with neck pain, restricted range of motion, or neurologic deficits, although symptoms may be subtle or masked by altered mental status or distracting injuries. Abnormal vital signs such as hypotension, bradycardia, or respiratory compromise may indicate spinal cord involvement.
On examination, findings may include midline cervical tenderness, muscle spasm, and neurologic abnormalities such as paresthesias, weakness, flaccidity, or paralysis. Specific spinal cord syndromes may also be identified. For example, anterior cord syndrome results in motor paralysis with loss of pain sensation but preserved proprioception, while central cord syndrome typically causes greater weakness in the upper extremities than the lower. Brown-Séquard syndrome presents with asymmetric motor and sensory deficits. In preverbal children, assessment is particularly challenging, as they may not be able to communicate symptoms effectively.
Evaluation requires a cautious and systematic approach. Cervical spine radiographs are the initial imaging modality in children with concerning features such as pain, neurologic symptoms, altered consciousness, or significant mechanism of injury. Standard views include anteroposterior, lateral, and odontoid projections, ensuring visualization of all cervical levels. However, interpretation can be difficult due to normal developmental variants, such as pseudosubluxation of C2 on C3 or incomplete ossification of vertebral structures, which may mimic injury. CT scanning is indicated when radiographs are inconclusive or suspicious, while MRI is essential when spinal cord injury is suspected, particularly in cases of SCIWORA.
Clinical decision tools such as the NEXUS criteria may be applied in children older than 8 years, but are less reliable in younger patients. Therefore, a lower threshold for imaging is often necessary in younger children.
Management begins with strict cervical spine immobilization, using appropriately sized collars and supportive padding. Due to the relatively large head in young children, padding beneath the torso may be required to maintain neutral alignment and prevent neck flexion. During airway management, in-line stabilization must be maintained, and patients should be logrolled carefully. In sports injuries, helmets should generally be left in place unless they interfere with airway management.
In the emergency setting, any child with neurologic deficits or confirmed injury requires urgent neurosurgical or orthopedic consultation. The use of high-dose corticosteroids such as methylprednisolone remains controversial and should only be considered in consultation with specialists, given the risk of complications such as immunosuppression.
All children with altered mental status, neurologic deficits, or confirmed fractures should be admitted for monitoring and further management. Children with normal mental status, no imaging abnormalities, and no neurologic findings may be discharged with strict instructions. Importantly, caregivers must be educated about the possibility of delayed symptoms in SCIWORA, and advised to return immediately if the child develops weakness, numbness, or paralysis.
Key pitfalls include failure to recognize the unique anatomy of the pediatric cervical spine, misinterpreting normal variants as injuries or vice versa, and underestimating the potential for delayed neurologic deterioration. Maintaining immobilization throughout evaluation, using appropriate imaging, and ensuring close follow-up are essential to prevent missed injuries and improve outcomes.

Emergency and Acute Medicine: Lumbar Spine Injury
Lumbar spine injuries result from significant mechanical forces applied to the lower back, most commonly due to blunt trauma such as motor vehicle accidents, falls from height, or direct impact. These injuries can involve a wide spectrum, ranging from stable compression fractures to highly unstable injuries with neurologic compromise. The type of injury depends on the mechanism involved, including flexion, compression, distraction, rotation, extension, or shear forces.
Flexion-compression injuries include wedge fractures, which are typically stable when less than 50% of the vertebral body height is lost and are not associated with ligamentous disruption or neurologic deficits. In contrast, burst fractures are more severe and involve retropulsion of bone fragments into the spinal canal, often causing kyphotic deformity and potential neurologic injury. Flexion-distraction injuries, such as the classic Chance fracture, are often associated with seatbelt injuries and may coexist with intra-abdominal trauma. More severe patterns like facet dislocations, rotational injuries, and translational (shear) injuries involve significant ligamentous disruption and are frequently unstable with a high risk of neurologic deficits. Less severe injuries include isolated spinous or transverse process fractures, which are generally stable but may occasionally involve nerve root irritation.
Patients typically present with midline lumbar pain, tenderness, bruising, deformity, or muscle spasm. Physical examination may reveal increased interspinous distance or a palpable step-off suggesting vertebral displacement. Neurologic deficits may occur depending on the level and severity of injury, including weakness, sensory loss, reflex abnormalities, or loss of bladder control. Pain may be masked in patients with multiple injuries or altered mental status, making imaging essential in these cases.
A detailed neurologic examination is crucial and should include assessment of motor strength, sensory levels, reflexes, rectal tone, and perineal sensation. Specific nerve root functions can help localize injury—for example, ankle dorsiflexion (L4–L5), toe extension (L5), and knee reflexes (L2–L4). Clinical suspicion should be high in patients with high-risk mechanisms, altered consciousness, intoxication, or distracting injuries.
Imaging plays a central role in diagnosis. Initial evaluation typically includes anteroposterior and lateral lumbar radiographs, but these may miss certain injuries, including up to 25% of burst fractures. Features suggesting instability include significant vertebral height loss (>50%), kyphosis, widening of interspinous distance, or vertebral translation. Therefore, CT scanning is often required for further characterization and assessment of spinal canal involvement, while MRI is indicated when there is concern for spinal cord or ligamentous injury.
Management begins with strict spinal immobilization and standard trauma resuscitation (ABCs). Patients with neurologic deficits or unstable fractures require urgent consultation with orthopedic spine or neurosurgical specialists. The use of high-dose corticosteroids such as methylprednisolone remains controversial and should be considered only in consultation with specialists.
Stable injuries in neurologically intact patients—such as minor compression fractures, isolated transverse or spinous process fractures, and some stable burst fractures—may be managed conservatively. Treatment includes pain control, activity modification, and sometimes bracing or orthotic support. Patients are advised to limit activities, avoid positions that worsen deformity, and follow structured recovery plans.
All patients with lumbar fractures generally require hospital admission for monitoring, pain management, and evaluation for associated injuries. However, selected patients with stable injuries and no neurologic deficits may be discharged with close follow-up, provided that imaging confirms stability and adequate support systems are in place.
Important pitfalls include missing unstable injuries on plain radiographs, underestimating injury severity in patients with distracting injuries, and failing to recognize alternative diagnoses such as infection, malignancy, or hematoma—especially in elderly or anticoagulated patients. Early imaging with CT, careful neurologic assessment, and specialist involvement are essential to optimize outcomes and prevent complications.

Emergency and Acute Medicine: Coccyx Injury
Coccyx injury, commonly referred to as a tailbone injury, typically occurs after a fall in which the individual lands in a seated position, often from standing height. It may also occur during childbirth and is more frequently seen in women. These injuries are usually isolated and involve trauma to the distal end of the spine without associated neurologic compromise.
Patients typically present with localized pain and tenderness over the coccyx, often accompanied by bruising in the gluteal region. The pain is characteristically worsened by sitting—especially when leaning forward—and during defecation. A careful history should include the mechanism of injury and any preceding events that might explain the fall. On physical examination, focal tenderness is usually present, and a rectal exam may reveal pain or abnormal mobility of the coccyx. Importantly, neurologic deficits are not expected in isolated coccygeal injuries, and their presence should prompt evaluation for more serious spinal pathology.
Diagnosis is primarily clinical. Routine imaging is generally not necessary, as coccygeal fractures are difficult to interpret radiographically due to normal anatomical variations, and imaging exposes the gonads to unnecessary radiation. If imaging is required—such as when other spinal injuries are suspected—a lateral radiograph is the most useful view for identifying fractures or dislocations.
Management is conservative in most cases. Initial care focuses on pain control and exclusion of other injuries. In the emergency setting, analgesics are provided, and patients are advised on comfort measures. A key recommendation is the use of a donut-shaped cushion, which reduces pressure on the coccyx during sitting. Stool softeners are often prescribed to minimize pain during bowel movements.
Reduction of a displaced coccygeal fracture may be attempted in rare cases but is seldom necessary or successful. Most patients can be safely managed as outpatients, and hospital admission is rarely required unless there are associated injuries or complications.
Conditions that may mimic coccyx injury include coccygodynia, levator ani syndrome, pilonidal cyst, and perirectal abscess. A careful clinical evaluation helps distinguish these entities.
Overall, coccyx injuries are benign but can be quite painful. The mainstay of care is symptom management and patient education, with reassurance that most cases improve over time without the need for invasive intervention.

🚑 Emergency and Acute Medicine: Staphylococcal Scalded Skin Syndrome
Staphylococcal scalded skin syndrome (SSSS) is a toxin-mediated dermatologic condition caused by exfoliative toxins produced by Staphylococcus aureus. These toxins are generated at a distant site of infection or colonization and spread through the bloodstream, leading to cleavage within the superficial epidermis. Specifically, they disrupt desmosomes in the granular layer, resulting in widespread skin separation and exfoliation. The condition most commonly affects infants and young children under 6 years of age due to their immature immune systems and reduced ability to clear toxins. It may also occur in immunocompromised adults or those with significant renal dysfunction.
SSSS often arises from seemingly minor or occult sources of infection such as the nasopharynx, conjunctiva, umbilicus, urinary tract, or small skin breaks. In many cases, no obvious primary focus is identified. The disease spectrum includes localized forms such as bullous impetigo and more severe generalized forms, including Ritter disease in neonates. The clinical severity depends on patient age and extent of toxin dissemination.
The illness typically begins abruptly with nonspecific symptoms such as fever, irritability, and malaise. This is followed by the rapid development of a diffuse, erythematous rash resembling sunburn, often described as having a “sandpaper-like” texture. The skin is extremely tender, especially in flexural and intertriginous areas such as the neck, axillae, groin, and around the eyes and mouth. Within 1 to 3 days, flaccid bullae form and rupture easily, leading to widespread peeling of the epidermis. A hallmark feature is the Nikolsky sign, where gentle pressure causes the superficial skin layers to separate. Despite the dramatic skin findings, mucous membranes are typically spared, which helps distinguish SSSS from more severe conditions like toxic epidermal necrolysis.
Diagnosis is primarily clinical. Laboratory tests may be used to assess systemic involvement or identify the source of infection, but fluid from the bullae is usually sterile due to the toxin-mediated nature of the disease. Cultures from other sites, such as the nasopharynx or conjunctiva, may reveal the causative organism. In atypical cases, a skin biopsy can confirm the level of epidermal separation.
Management is similar to treating a superficial burn. Patients require careful fluid and electrolyte management, pain control, and protection of the skin barrier. Gentle handling, sterile dressings, and temperature regulation are essential. Prompt initiation of antibiotics targeting penicillin-resistant S. aureus is critical. Intravenous agents such as cefazolin or nafcillin are commonly used, with vancomycin reserved for suspected MRSA. Mild cases in older children may be treated with oral antibiotics such as cephalexin or dicloxacillin.
Hospital admission is required for infants, toxic-appearing patients, or those with extensive skin involvement or dehydration. Complications, though uncommon, include fluid loss, electrolyte imbalance, secondary infections, and sepsis. With appropriate treatment, recovery is typically rapid and complete within two weeks, without scarring.
Important clinical pitfalls include confusing SSSS with other dermatologic emergencies such as toxic epidermal necrolysis or scarlet fever, and failing to identify the underlying source of infection. Early recognition and treatment are essential to prevent complications and ensure favorable outcomes.

Emergency and Acute Medicine: Spontaneous Bacterial Peritonitis
Spontaneous bacterial peritonitis (SBP) is an infection of ascitic fluid that occurs without an identifiable surgically treatable intra-abdominal source. It is diagnosed when the ascitic fluid polymorphonuclear leukocyte (PMN) count exceeds 250 cells/mm³, typically with a positive culture. Distinguishing SBP from secondary bacterial peritonitis is critical, as mismanagement carries severe consequences—secondary peritonitis requires surgery, while surgical intervention in SBP is associated with high mortality. SBP is common in patients with ascites, particularly those with liver cirrhosis, with an annual incidence of up to 30%.
The condition arises primarily due to bacterial translocation from the gut. Portal hypertension leads to bowel wall edema, allowing intestinal bacteria to migrate into the peritoneal cavity. Additional contributing factors include transient bacteremia, impaired immune defenses, and reduced complement activity. Gastrointestinal bleeding further increases risk by compromising mucosal barriers. Although SBP is most commonly associated with cirrhosis, it can rarely occur in other causes of ascites such as nephrotic syndrome or heart failure. The most frequent pathogens are aerobic gram-negative organisms such as Escherichia coli and Klebsiella, followed by gram-positive organisms like streptococci.
Clinical presentation is often subtle, and up to one-third of patients may be asymptomatic. When symptoms occur, they may include mild diffuse abdominal pain, fever, chills, diarrhea, worsening ascites, or altered mental status. On examination, fever is the most common finding, though cirrhotic patients may have only low-grade elevations in temperature. Abdominal tenderness may be present, but classic peritonitis signs like rigidity are often absent due to the presence of ascitic fluid separating peritoneal layers.
Paracentesis is the cornerstone of diagnosis and should be performed in all patients with ascites and suspected infection. The procedure is safe even in the presence of coagulopathy, except in severe thrombocytopenia. Ascitic fluid analysis includes cell count, culture, and biochemical markers. A PMN count above 250 cells/mm³ confirms the diagnosis, even if cultures are negative. Additional findings may include low protein levels, low glucose, elevated lactate dehydrogenase, and acidic pH. Blood tests are supportive and reflect underlying liver disease rather than the infection itself. Imaging is primarily used to exclude secondary causes such as perforation or abscess.
Management begins with prompt empiric antibiotic therapy after diagnostic paracentesis. Third-generation cephalosporins such as cefotaxime or ceftriaxone are first-line treatments. Alternative regimens include broad-spectrum β-lactam combinations, depending on patient factors. Aminoglycosides and fluoroquinolones are generally avoided due to toxicity and resistance concerns. Intravenous albumin is recommended in high-risk patients to reduce the risk of renal failure and improve survival. Early treatment is essential, as SBP carries significant mortality and may precipitate complications such as hepatorenal syndrome.
All patients with SBP require hospital admission for intravenous antibiotics and monitoring. Intensive care may be necessary for those with septic shock or severe hepatic encephalopathy. Discharge is not appropriate unless SBP has been definitively excluded or the patient refuses admission under carefully selected low-risk conditions. Long-term management often includes prophylactic antibiotics to prevent recurrence, particularly in high-risk individuals.
Key clinical pitfalls include failing to perform early paracentesis, overlooking SBP in patients with minimal symptoms, and not excluding secondary peritonitis. Because presentation can be subtle, a high index of suspicion is essential in any patient with ascites who develops clinical deterioration. Early diagnosis and timely treatment significantly improve outcomes.
Spontaneous bacterial peritonitis (SBP) is an infection of ascitic fluid that occurs without an identifiable surgically treatable intra-abdominal source. It is diagnosed when the ascitic fluid polymorphonuclear leukocyte (PMN) count exceeds 250 cells/mm³, typically with a positive culture. Distinguishing SBP from secondary bacterial peritonitis is critical, as mismanagement carries severe consequences—secondary peritonitis requires surgery, while surgical intervention in SBP is associated with high mortality. SBP is common in patients with ascites, particularly those with liver cirrhosis, with an annual incidence of up to 30%.
The condition arises primarily due to bacterial translocation from the gut. Portal hypertension leads to bowel wall edema, allowing intestinal bacteria to migrate into the peritoneal cavity. Additional contributing factors include transient bacteremia, impaired immune defenses, and reduced complement activity. Gastrointestinal bleeding further increases risk by compromising mucosal barriers. Although SBP is most commonly associated with cirrhosis, it can rarely occur in other causes of ascites such as nephrotic syndrome or heart failure. The most frequent pathogens are aerobic gram-negative organisms such as Escherichia coli and Klebsiella, followed by gram-positive organisms like streptococci.
Clinical presentation is often subtle, and up to one-third of patients may be asymptomatic. When symptoms occur, they may include mild diffuse abdominal pain, fever, chills, diarrhea, worsening ascites, or altered mental status. On examination, fever is the most common finding, though cirrhotic patients may have only low-grade elevations in temperature. Abdominal tenderness may be present, but classic peritonitis signs like rigidity are often absent due to the presence of ascitic fluid separating peritoneal layers.
Paracentesis is the cornerstone of diagnosis and should be performed in all patients with ascites and suspected infection. The procedure is safe even in the presence of coagulopathy, except in severe thrombocytopenia. Ascitic fluid analysis includes cell count, culture, and biochemical markers. A PMN count above 250 cells/mm³ confirms the diagnosis, even if cultures are negative. Additional findings may include low protein levels, low glucose, elevated lactate dehydrogenase, and acidic pH. Blood tests are supportive and reflect underlying liver disease rather than the infection itself. Imaging is primarily used to exclude secondary causes such as perforation or abscess.
Management begins with prompt empiric antibiotic therapy after diagnostic paracentesis. Third-generation cephalosporins such as cefotaxime or ceftriaxone are first-line treatments. Alternative regimens include broad-spectrum β-lactam combinations, depending on patient factors. Aminoglycosides and fluoroquinolones are generally avoided due to toxicity and resistance concerns. Intravenous albumin is recommended in high-risk patients to reduce the risk of renal failure and improve survival. Early treatment is essential, as SBP carries significant mortality and may precipitate complications such as hepatorenal syndrome.
All patients with SBP require hospital admission for intravenous antibiotics and monitoring. Intensive care may be necessary for those with septic shock or severe hepatic encephalopathy. Discharge is not appropriate unless SBP has been definitively excluded or the patient refuses admission under carefully selected low-risk conditions. Long-term management often includes prophylactic antibiotics to prevent recurrence, particularly in high-risk individuals.
Key clinical pitfalls include failing to perform early paracentesis, overlooking SBP in patients with minimal symptoms, and not excluding secondary peritonitis. Because presentation can be subtle, a high index of suspicion is essential in any patient with ascites who develops clinical deterioration. Early diagnosis and timely treatment significantly improve outcomes.

Emergency and Acute Medicine: Splenic Injury
Splenic injury is one of the most important considerations in abdominal trauma, as the spleen is the most commonly injured intra-abdominal organ. Located in the left upper quadrant between the stomach and diaphragm, the spleen is highly vascular and therefore prone to bleeding when injured. In many cases, it is the only organ affected, particularly in blunt trauma scenarios such as motor vehicle accidents, falls, or direct blows to the abdomen. The severity of injury is classified using grading systems based on the extent of hematoma, laceration, and vascular involvement, ranging from minor capsular tears to complete splenic destruction.
The mechanism of injury plays a crucial role in diagnosis. Blunt trauma often results from compression of the spleen between the abdominal wall and posterior structures, while penetrating trauma causes damage through direct tissue disruption and energy transfer. In children, anatomical differences such as a more compliant rib cage and less protective musculature increase susceptibility to splenic injury, while in older adults, reduced physiologic reserve increases the risk of poor outcomes.
Clinical presentation varies widely. Patients may exhibit signs of internal bleeding, including dizziness, weakness, syncope, or hypotension. Local findings often include left upper quadrant tenderness, abdominal distention, and guarding. Classic signs include Kehr sign (referred pain to the left shoulder due to diaphragmatic irritation) and Balance sign (a palpable LUQ mass). Associated findings such as lower left rib fractures or external bruising over the abdomen or flank may further raise suspicion. However, history and physical examination alone are neither sensitive nor specific, making imaging essential.
Initial evaluation follows standard trauma protocols, including airway, breathing, and circulation management. Laboratory studies such as hemoglobin and type and cross-match are obtained but are not diagnostic. Imaging is critical, with focused assessment with sonography for trauma (FAST) used at the bedside to detect free intraperitoneal fluid. While FAST is useful for identifying bleeding, it does not reliably assess the extent of splenic injury. CT scanning with contrast is the gold standard in hemodynamically stable patients, as it provides detailed information about the injury grade and associated intra-abdominal pathology. In unstable patients, immediate surgical intervention may be required without advanced imaging.
Management depends primarily on hemodynamic stability and injury severity. Patients who are unstable or have signs of ongoing hemorrhage typically require emergent laparotomy, often with splenectomy. In contrast, the majority of stable patients—especially those with lower-grade injuries (Grades I–III)—can be managed nonoperatively with close monitoring, serial examinations, and repeat laboratory testing. Angiographic embolization is an important adjunct in selected stable patients with evidence of ongoing bleeding.
Special considerations apply to different populations. In children, nonoperative management is strongly favored to preserve splenic function and reduce the risk of overwhelming post-splenectomy infection. In older adults, however, operative management may be more frequently required due to decreased physiologic reserve and increased risk of complications.
All patients diagnosed with splenic injury require hospital admission for observation or surgical management. Only patients definitively shown to have no splenic or intra-abdominal injury may be safely discharged.
Key pitfalls include relying too heavily on physical examination, missing occult bleeding, and underestimating injury severity in initially stable patients. Early imaging, repeated reassessment, and careful monitoring are essential to prevent delayed recognition of life-threatening hemorrhage.

Emergency and Acute Medicine: Spondylolysis and Spondylolisthesis
Spondylolysis is a structural defect in the pars interarticularis, the portion of bone between the superior and inferior articular facets of a vertebra. This defect may occur on one side or both sides, with bilateral involvement significantly increasing the risk of progression to spondylolisthesis, a condition in which one vertebra slips forward over the one beneath it. Spondylolisthesis affects approximately 5% of the population and is more common in males. About half of patients with spondylolysis will develop some degree of vertebral slippage, and roughly half of those individuals will experience symptoms. This condition often leads to nerve root compression, frequently causing sciatica.
Spondylolisthesis is categorized based on underlying cause and severity. Etiologic types include congenital (dysplastic), stress-related (isthmic), degenerative, traumatic, and pathologic forms. Severity is graded using the Meyerding classification, ranging from Grade I (≤25% slippage) to Grade IV (75–100%). The most commonly affected level is L5 slipping over S1, followed by L4 over L5. In pediatric populations, spondylolysis is a common cause of significant low back pain, particularly during adolescent growth spurts. It is frequently seen in young athletes engaged in sports involving repetitive spinal extension, such as gymnastics, diving, and football.
The exact cause of spondylolysis remains uncertain but is thought to involve a combination of congenital susceptibility, altered bone density, and repetitive microtrauma. Symptoms usually develop gradually, unless triggered by acute injury. Patients commonly report low back pain associated with muscle stiffness or spasms, which may radiate to the proximal legs. Pain is typically worsened by standing, walking, or hyperextension and relieved by sitting or forward bending. Neurologic symptoms are generally absent unless significant vertebral displacement leads to nerve compression.
On physical examination, patients may demonstrate a hyperlordotic posture with a shortened trunk appearance and tight hamstrings. A classic diagnostic maneuver is the one-legged hyperextension test, where standing on one leg and leaning backward reproduces pain on the affected side. In more advanced cases, a palpable step-off may be detected over the lumbar spine. Neurologic examination is usually normal but may reveal dermatomal sensory or motor deficits if nerve involvement is present.
Diagnosis is primarily radiologic. Plain lumbosacral spine radiographs, especially oblique views, may reveal a defect in the pars interarticularis, often described as the “Scottie dog” sign with a “broken neck.” Lateral views help identify vertebral slippage. CT scanning provides more detailed visualization of bony abnormalities and is useful in evaluating fracture acuity and healing, while MRI can assess nerve root compression and other soft tissue pathology. In children, imaging is pursued more readily due to the higher risk of progression.
Management is typically conservative. Treatment focuses on pain control, activity modification, and gradual return to activity once symptoms improve. Patients are advised to avoid activities involving repetitive spinal extension for several weeks. Physical therapy and, in some cases, bracing may be considered. Surgical intervention, usually spinal fusion, is reserved for patients with severe symptoms, high-grade slippage (Grade III or IV), or those who fail conservative therapy.
Medications may include NSAIDs, muscle relaxants, and, when necessary, short-term opioids for pain control. Hospital admission is indicated for patients who are unable to ambulate, cannot manage pain at home, or develop new or worsening neurologic deficits. Most patients can be managed as outpatients with appropriate follow-up and education. Pediatric patients require especially close monitoring due to the higher likelihood of progression.
Important pitfalls include missing the diagnosis in adolescents with persistent back pain, failing to recognize progressive neurologic deficits, and overlooking alternative diagnoses such as infection, tumor, or disc disease. Early identification and appropriate management are key to preventing progression and long-term complications.

Emergency and Acute Medicine: Thoracic Spine Injury
Thoracic spine injuries are typically the result of high-energy trauma, as the thoracic region is relatively rigid due to stabilization by the rib cage and costovertebral joints. Common mechanisms include axial compression, flexion–rotation, shear forces, flexion–distraction, and extension. Because of this rigidity, a large force is usually required to produce fractures or dislocations, most commonly seen in motor vehicle collisions, falls from significant heights, or high-impact trauma. The thoracic spinal canal is also relatively narrow, increasing the risk of neurologic injury when fractures occur—especially near the thoracolumbar junction (T11–L2), where a large proportion of spinal injuries are concentrated.
The stability of the thoracic spine is best understood using the three-column model. The anterior column includes the anterior vertebral body and supporting ligaments, the middle column consists of the posterior vertebral body and posterior longitudinal ligament, and the posterior column includes the vertebral arch and ligamentous structures. Injury involving two or more columns indicates instability, which significantly increases the risk of neurologic compromise.
Thoracic spine fractures are broadly categorized into minor and major injuries. Minor fractures include isolated spinous process, transverse process, or articular fractures, which are generally stable. Major injuries include compression fractures, burst fractures, seatbelt (flexion–distraction) injuries, and fracture-dislocations. Compression fractures typically involve the anterior column and may remain stable if the middle column is intact. In contrast, burst fractures involve the middle column and may result in retropulsion of bone fragments into the spinal canal, posing a risk of spinal cord compression. Flexion–distraction injuries, often associated with improper seatbelt use, disrupt posterior and middle columns, while fracture-dislocations represent complete failure of all three columns and are highly unstable with a high likelihood of neurologic injury.
Clinically, patients usually present with localized thoracic back pain, tenderness, bruising, or deformity, such as step-offs or widened interspinous spaces. Pain may also be referred to the chest or abdomen. Because of the force required to injure the thoracic spine, associated internal injuries should always be suspected, including thoracic, abdominal, or vascular trauma. Neurologic findings may include paresthesia, weakness, loss of reflexes, bowel or bladder dysfunction, or signs of spinal shock such as hypotension with bradycardia. The presence of injury at another spinal level should increase suspicion for thoracic involvement.
Evaluation begins with primary trauma assessment (ABCs) followed by a detailed neurologic and spinal examination, including rectal tone and perianal sensation. Any patient with midline tenderness, altered mental status, intoxication, distracting injuries, or significant mechanism of injury should undergo imaging. Initial imaging typically includes anteroposterior and lateral radiographs, but CT scanning is more sensitive and is often required for definitive assessment. CT is particularly useful for identifying fractures and evaluating stability, while MRI is indicated when there is concern for spinal cord injury, ligamentous damage, or neurologic deficits. Importantly, identification of a fracture in one region of the spine mandates imaging of the entire spine, as multiple injuries are not uncommon.
Management requires strict spinal immobilization throughout evaluation and resuscitation. Airway management should be performed with in-line stabilization, and hypotension should initially be assumed to result from hemorrhage until proven otherwise. Neurogenic shock, characterized by hypotension with bradycardia and warm extremities, should be distinguished from hypovolemic shock and may require vasopressor support in addition to fluid resuscitation.
Patients with suspected spinal cord injury or unstable fractures require urgent consultation with neurosurgical or orthopedic spine specialists and should be managed in a trauma center. Pain control with opioids, NSAIDs, and adjuncts is essential. The use of high-dose corticosteroids remains controversial and is no longer routinely recommended, though it may be considered in select cases within a limited time window after injury.
Admission is indicated for patients with unstable injuries, neurologic deficits, significant pain, ileus, or associated trauma. ICU care may be required depending on severity. Selected patients with stable minor fractures and no neurologic impairment may be discharged after specialist evaluation, with close outpatient follow-up.
Key pitfalls include failure to recognize thoracic spine injury in patients with major trauma, underuse of CT imaging in high-risk cases, and premature removal of spinal precautions. Maintaining immobilization until injury is definitively excluded, performing thorough neurologic assessments, and involving specialists early are critical steps in preventing missed injuries and improving patient outcomes.
