Select bone biopsy when the clinical scenario suggests osteomyelitis and definitive diagnosis is required, especially in:
2. For which diseases is this the gold-standard diagnostic test?
A needle aspirate bone biopsy examined microscopically is the gold-standard diagnostic test for:
It allows for histologic evaluation and microbiologic culture.
3. What tests can replace this biopsy if osteomyelitis is suspected?

1. When is bone biopsy the appropriate choice?

- Patients with diabetes mellitus and peripheral vascular disease
- Chronic leg or foot pain with:
- Warmth
- Ulceration
- Imaging abnormalities on X-ray or MRI consistent with bone infection
2. For which diseases is this the gold-standard diagnostic test?
A needle aspirate bone biopsy examined microscopically is the gold-standard diagnostic test for:
- Osteomyelitis
- Primary bone tumors
- Metastatic bone (osseous) disease
It allows for histologic evaluation and microbiologic culture.
3. What tests can replace this biopsy if osteomyelitis is suspected?
A bone biopsy may be avoided when both of the following are present:
- Radiographic evidence of osteomyelitis (X-ray or MRI findings)
- Positive blood cultures identifying a causative organism
In this setting, the diagnosis of osteomyelitis can be established without biopsy.
