A free high-yield preview for the UKMLA Applied Knowledge Test, covering how to recognise this condition. The full SA Note notes add investigations, management and complications, with practice questions on this topic.
Key high-yield points
- Location - pressure points: plantar 1st/5th metatarsophalangeal joint, heel, under calluses
- Painless - cardinal feature; patient may be unaware of ulcer entirely
- Punched-out appearance with deep sinus tract
- Surrounding callus - often overlies or conceals the ulcer
- Warm foot with palpable pulses - if arterial supply intact (distinguishes from arterial ulcer)
- Brisk bleeding on probing/debridement (unlike arterial ulcers)
- Dry, fissured skin from autonomic dysfunction (anhidrosis)
