Background
How to tell the difference between two conditions that look very similar in a diabetic foot — acute Charcot neuroarthropathy (a non-infectious collapse of the bones) and acute infection — both of which produce a hot, swollen, red foot.
Rationale
Treating a Charcot foot as if it were infected (with antibiotics and surgical debridement) makes things worse. Treating an infected foot as if it were Charcot (with offloading and casting) lets infection rage. The two conditions need opposite responses, but on first inspection they look alarmingly similar.
What did we conclude
No single test gets you to the answer. The diagnosis requires combining multiple criteria: presence of neuropathy, the history (sudden swelling without trauma points to Charcot; an open wound or progressive symptoms point to infection), specific imaging findings, and at times bone biopsy.
Implications
A hot diabetic foot needs urgent specialist assessment by a clinician used to seeing both. Don’t accept a snap diagnosis from a single test — the workup needs to combine several pieces of evidence before treatment is committed to.
