Presentation
Post amputation of the foot.
Patient Data
Radiographs show amputation/disarticulation at the level of the talonavicular and calcaneocuboid joints, consistent with Chopart amputation. There is soft tissue irregularity/ulceration at the stump.
Case Discussion
In a Chopart amputation, the disarticulation is at the calcaneocuboid and talonavicular joints (Chopart joint). This requires a viable heel pad 1. Complications following Chopart amputation are common and include rebalancing and prosthesis fitting issues. Many patients may subsequently require below-knee amputations 2. Chopart amputation is rarely performed in patients with diabetic foot infection because of the high rate of failure 3.
