Surgical Signs, Tests, Laws, Syndromes and Eponyms
Allen’s Test
Allen’s test is used to assess the circulation of the hand and the patency of the radial and ulnar arteries. The patient is asked to drain the hand of blood by forming a fist while the examiner compresses both the radial and ulnar arteries. The patient then opens the hand, which should appear blanched. One artery is released and the examiner observes for palmar flushing, indicating arterial patency. The procedure is then repeated for the other artery.
Argyll Robertson Pupil
Argyll Robertson pupil is a condition in which the pupil constricts or dilates appropriately during accommodation but does not respond to light. In other words, the accommodation reflex is preserved while the pupillary light reflex is absent. A useful mnemonic is ARP, PRA, which translates to Accommodation Reflex Present, Pupillary Response Absent.
Barton’s Fracture
Barton’s fracture is a fracture-dislocation of the distal radius and may sometimes be mistaken for a Colles’ fracture. The fracture line extends across the volar lip of the radius and into the wrist joint. The hand and the associated fragment of distal radius undergo proximal and volar displacement.
Battle’s Sign
Battle’s sign is ecchymosis over the mastoid or post-auricular region and is associated with a basal skull fracture. It is an important clinical sign indicating possible fracture of the base of the skull.
Beck’s Triad
Beck’s triad is classically seen in cardiac tamponade. It consists of jugular venous distension, muffled heart sounds, and decreased blood pressure or hypotension. These findings result from impaired cardiac filling due to pressure from fluid within the pericardial sac.
Bell’s Palsy
Bell’s palsy is an acute lower motor neurone facial nerve palsy of unknown aetiology. It produces weakness or paralysis of the muscles on one side of the face and is generally regarded as a diagnosis of exclusion.
Chvostek’s Sign
Chvostek’s sign is seen in hypocalcaemia. It is elicited by tapping over the facial nerve, which causes twitching or contraction of the facial muscles due to increased neuromuscular excitability.
Colles’ Fracture
A Colles’ fracture is a fracture of the distal approximately 2 cm of the radius with dorsal displacement of the distal fragment. This produces the characteristic dinner-fork deformity of the wrist.
Compartment Syndrome
Compartment syndrome is a condition in which pressure increases within a confined anatomical compartment. The rising pressure adversely affects circulation and threatens the function and viability of the muscles, nerves, and other tissues within that compartment.
Cushing’s Triad
Cushing’s triad is seen in raised intracranial pressure. It consists of increased blood pressure, bradycardia, and irregular respirations. These findings may indicate severe intracranial hypertension.
De Quervain’s Tenosynovitis
De Quervain’s tenosynovitis is inflammation of the extensor pollicis brevis (EPB) and abductor pollicis longus (AbPL) tendons, usually secondary to overuse. It causes pain around the radial side of the wrist and may be demonstrated clinically using Finkelstein’s test.
Finkelstein’s Test
Finkelstein’s test is used to assess for De Quervain’s tenosynovitis. The thumb is clenched within the fist and the wrist is moved in a way that stretches the extensor pollicis brevis and abductor pollicis longus tendons. Reproduction of pain over the radial aspect of the wrist supports the diagnosis.
Frey’s Syndrome
Frey’s syndrome is characterized by warmth, flushing, and sweating in the malar or parotid region of the face during eating, or even when thinking or talking about food. It is also known as gustatory sweating. It may follow damage in the parotid region caused by trauma, mumps, purulent infection, or parotidectomy. After the initial damage, autonomic fibres that previously supplied the salivary glands may regenerate incorrectly and connect with sweat glands. As a result, a stimulus that normally causes salivation instead causes sweating and flushing. Flushing has been described as more prevalent in females and sweating as more prevalent in males. Gustatory tears, also known as crocodile tears, may sometimes occur.
Galeazzi Fracture
A Galeazzi fracture is a fracture of the radial shaft associated with dislocation of the distal radioulnar joint. This disrupts the normal forearm axis. It is sometimes referred to as a reverse Monteggia fracture.
Gradenigo’s Syndrome
Gradenigo’s syndrome is seen as a complication of suppurative otitis media. It consists of signs of acute suppurative otitis media, ipsilateral abducens nerve palsy, and pain in the distribution of the ipsilateral trigeminal nerve.
Hitselberger’s Sign
Hitselberger’s sign is an abnormal sensory change involving the posterior external auditory canal, classically associated with acoustic neuroma. It may occur together with ipsilateral hearing loss.
Horner’s Syndrome
Horner’s syndrome results from disruption of the ipsilateral sympathetic nerve supply to the eye and face. It is characterized by ipsilateral ptosis, miosis, anhidrosis, and apparent enophthalmos. A classic cause is a Pancoast tumour, which is a tumour arising from the upper part or apex of the lung.
Monteggia Fracture
A Monteggia fracture consists of dislocation of the radial head associated with a fracture of the proximal third of the ulna.
Osler–Rendu–Weber Syndrome

Thoracic outlet syndrome occurs when structures passing through the thoracic outlet are compressed. Possible causes include a cervical rib. Depending on the structures affected, the patient may develop neurological or vascular symptoms involving the upper limb.
Thornwaldt’s Cyst
A Thornwaldt’s cyst is a benign cystic swelling of the nasopharynx and is uncommon, particularly in adults. It arises from the pharyngeal bursa and is located in the superoposterior nasopharynx. A sufficiently large cyst may contribute to obstruction in this region.
Treacher Collins Syndrome
Treacher Collins syndrome is an autosomal dominant craniofacial disorder characterized by hypoplasia of the maxilla and mandible. Patients may also have microtia, meaning small or underdeveloped ears, together with abnormalities of the external, middle, or inner ear and associated hearing problems.
Trousseau’s Sign
Trousseau’s sign is seen in hypocalcaemia. It is demonstrated by producing temporary blood-flow occlusion with a blood pressure cuff, which causes carpopedal spasm due to increased neuromuscular excitability.
Waardenburg Syndrome
Waardenburg syndrome is an inherited disorder characterized by abnormalities of pigmentation and hearing. Features include telecanthus, pigment abnormalities such as a white forelock and heterochromia iridis, and sensorineural hearing loss. Telecanthus refers to an increased distance between the inner corners of the eyes.

Allen’s Test
Allen’s test is used to assess the adequacy of blood flow to the hand via the radial and ulnar arteries. The patient is asked to clench their fist to expel blood while both arteries are compressed. After opening the blanched hand, one artery is released to observe if normal color returns, indicating patency. The process is then repeated for the other artery.
Argyll Robertson Pupil
Argyll Robertson pupil is characterized by pupils that constrict during accommodation (focusing on near objects) but do not respond to light. This dissociation is remembered by the mnemonic: Accommodation Reflex Present, Pupillary Response Absent.
Barton’s Fracture

Bell’s palsy is an acute lower motor neuron facial nerve paralysis of unknown cause. It presents with unilateral facial weakness and is diagnosed after excluding other causes.
Chvostek’s Sign
Chvostek’s sign is a clinical sign of hypocalcaemia. Tapping over the facial nerve triggers twitching of the facial muscles.
Colles’ Fracture
Colles’ fracture is a fracture of the distal radius, typically within 2 cm of the wrist joint, with dorsal displacement of the distal fragment, producing a characteristic “dinner fork” deformity.
Compartment Syndrome
Compartment syndrome occurs when pressure within a closed anatomical space rises to a level that compromises circulation and tissue viability, potentially leading to permanent damage if untreated.
Cushing’s Triad
Cushing’s triad is associated with raised intracranial pressure and consists of hypertension, bradycardia, and irregular respirations.
De Quervain’s Tenosynovitis
De Quervain’s tenosynovitis is inflammation of the extensor pollicis brevis and abductor pollicis longus tendons due to repetitive use, causing pain on thumb movement.
Finkelstein’s Test
Finkelstein’s test is used to diagnose De Quervain’s tenosynovitis. The patient makes a fist with the thumb inside, and ulnar deviation of the wrist causes pain due to tendon stretching.
Frey’s Syndrome
Frey’s syndrome is characterized by sweating and flushing over the cheek when eating or thinking about food. It occurs due to misdirected regeneration of autonomic fibers after parotid gland injury.
Galeazzi Fracture
Galeazzi fracture involves a fracture of the radial shaft with dislocation of the distal radioulnar joint, disrupting the forearm axis.

Etiology • The majority of cases are idiopathic, with the immune complexes believed to form in situ. The antigen in these instances remains unidentified. Some cases are due to other illnesses, such as malignancies, pharmaceuticals, infections, and systemic lupus erythematosus (SLE). In these instances, the immune complexes likely originate elsewhere and flow to the kidneys, where they are deposited in the glomeruli.
Pathogenesis Immune complexes in the glomerulus compromise the normal filtration barrier, resulting in significant proteinuria. Presentation of nephrotic syndrome.
Light microscopy • All glomeruli exhibit thickened, rigid capillary loops. • Silver staining reveals 'holes' in the glomerular basement membrane, indicative of immune deposits, and 'spikes' that signify the glomerular basement membrane's response to these deposits. • More advanced cases may additionally demonstrate tubulointerstitial fibrosis. Immunofluorescence Granular deposits of IgG and C3 are, by definition, diffusely present along the capillary loops.
• The presence of deposits of IgA, IgM, and C1q necessitates consideration of membranous nephropathy secondary to systemic lupus erythematosus (SLE). Electron microscopy • Subepithelial electron-dense immune deposits are observed, accompanied by a variable response in the surrounding basement membrane. • Podocytes exhibit diffuse effacement of foot processes. Prognosis: Approximately one-third of patients have illness progression.

Scrubbing up helps lessen the chance of infection from the surgeon to the patient. Using bactericidal soaps can lower the amount of organisms that can be cultured from skin swabs, but sterilizing the skin (especially sweat glands and hair follicles) is impossible. Surgical gloves can cause considerable bacterial development within 2 hours due to moisture and heat, even with contemporary cleaning solutions. Bactericidal soaps include chlorhexidine and povidone-iodine.
Protocol
When entering the theatre for the first time, introduce yourself to the senior scrub nurses. It is respectful and safe. It's important to understand the purpose and identity of those in the theatre.
How To Scrub
• Wet your hands and arms first. • Apply disinfecting soap and wash well. • Scrub under nails and excessively filthy areas with a sterile brush and disinfecting soap. Scrubbing too forcefully might cause irritation and have little bactericidal effect. • Use soap to thoroughly clean between fingers, back of hands, beneath fingernails, and base of thumbs. • Rinse well to eliminate soap and prevent skin irritation. • Rinse off, ensuring water runs off elbows. Dry your hands well before moving on to your arms.
How to Gown and Glove
: • Open the gown without touching the exterior 'face'. Do not put your hands through the cuffs. Pick up the right glove with your right hand still in the gown's cuff—palm side down, fingers pointing up towards your forearm. • Fold the other side of the glove's edge 'over' your right hand. • Insert your right hand into the glove. • Grab the left glove by the edge and pull it over the left hand's cuff. • Slide your left hand into the glove and adjust its position. Wearing eye protection and two pairs of gloves is a standard practice to prevent exposure to infectious pathogens. % Infection control strategies include hand hygiene and personal protective equipment (PPE).

Body cavity incisions Incisions that allow access to each bodily cavity are referred to in general terms.
• Laparotomy. An incision into the peritoneal cavity or retroperitoneal region. Laparotomies are classified based on their location in the abdomen, the tissues they traverse, or the individual who performed them
• Thoracotomy. Accessing the chest cavity, usually in the pleural space or posterior mediastinum. A median sternotomy is a form of thoracotomy that allows access to the anterior and middle mediastinum
. • Craniotomy. Accessing the skull's chambers. Incision closures Incisions are closed using certain basic ideas. • Fascial layers are ideal for supporting apposition and forming the primary abdominal closure. Heavy, non-permanent sutures are commonly used to close wounds. • When performing a craniotomy, bone flaws should be minimized to prevent movement. • Replace defects in fascial or bony structures with transposed or inserted tissues, such as skin, muscle, or polypropylene mesh. • Avoid large cavities and crevices between tissues to prevent infection-causing fluid accumulation.

Definition: A glomerulopathy with clinical symptoms of nephrotic syndrome and histologically normal glomeruli under light microscopy.
Epidemiology • Uncommon. • Most commonly seen in children aged 2-6 years, but can also affect adults. The exact reason is unknown, however recent data shows it may be due to immunological malfunction. • Research has shown that minimal change disease (MCD) can occur after exposure to drugs, bee stings, or venom.
Pathogenesis: • The podocyte is assumed to be the primary cell involved in MCD. • Normal podocyte activity is compromised, making the glomerular filtration barrier abnormally permeable to proteins.
Presentation: • Nephrotic syndrome. Light microscopy shows typical glomeruli. immune fluorescence • No specific immune deposition is present.
Electron microscopy reveals that podocyte foot processes are highly simplified and lack immune complexes.
Prognosis: • MCD typically results in full recovery, especially in youngsters. Adults with steroid-resistant disease should be closely watched as they may have FSGS (b p. 148) that was not detected during biopsy due to its focused character.

Surgery for neurological illness.
Cerebrovascular accidents (strokes) Anaesthetic drugs can disrupt cerebrovascular autoregulation, increasing the risk of re-infarction or infarction extension during ischemic episodes. Autoregulation is restored after around 6 weeks. • Haemorrhagic infarctions have a low risk of continued bleeding, especially with thromboprophylaxis. Strategies for reducing risk • Postpone all non-essential surgeries for 6 weeks after infarctions, particularly ischemic ones. • Patients with recent hemorrhagic events may not require thromboprophylaxis. • Control blood pressure throughout perioperative period to prevent hypotension and hypertension and stabilize cerebral blood flow. • Avoid placing the patient's head down on the operating table, as this can increase cerebral venous pressure.
Epilepsy
Paroxysmal neuronal discharge in different parts of the brain can disrupt awareness, movement, and sensory perception. Cerebral space-occupying lesions, uraemia, cerebral oedema, medication toxicity, and hypercalcaemia can all elicit symptoms similar to epilepsy. For patients with known epilepsy, the following measures are recommended. • Determine normal seizure frequency, severity, and prodrome characteristics. • Continue anticonvulsant medication during NBM and immediately after surgery. • If not possible, consult with an anesthetist or neurologist to determine the best bridging regime. • 0 Phenytoin interacts with several medicines used during the perioperative period. • Increase elimination of prednisone, warfarin, and lidocaine. Increase Phenytoin absoption orally through amiodarone, fluconazole, omeprazole, and paroxetine but reduced through antacids with magnesium, calcium, and aluminum and enteral feeding.
Myasthenia gravis
This autoimmune disease causes muscle weakness due to inadequate acetylcholine (ACh) receptors. The disease typically affects young adults and causes symptoms such as ptosis and diplopia, as well as weakness in the neck, limbs, and trunk. Patients may seek thymectomy as a treatment or as an unplanned procedure. Management involves the following: • Continue regular medication. Consider elective post-operative breathing for significant thoracic or upper abdominal surgery, or if the patient has a vital capacity of less than 2L. Consult with an anaesthetist and the ICU. If ventilation is extended after surgery, a tracheostomy may be necessary. Discuss this with the patient during the consent process. • Monitor for respiratory failure after surgery, which could be caused by muscle weakness. Precipitants include hypokalemia, infection, over- or under-treatment, and emotional or physical exertion.
