Summary
"In summary, osteomyelitis is a difficult diagnosis to make. Certainly there are specific tests – i.e. probing to bone, findings on x-ray in the right clinical setting – but no test is sensitive enough to rule out. Inflammatory markers can again aid in raising suspicion, but are insensitive to rule out. Keep a high index of suspicion, and either admit for MRI, or secure good follow-up for patients with diabetic foot ulcers that present acutely or subacutely."
