Chopart Amputation for Extensive Midfoot Ischemic Gangrene



Problem
An elderly patient with type 2 diabetes presented with extensive ischemic gangrene of the diabetic foot, extending beyond the forefoot into the midfoot. Revascularization with angioplasty was performed first to restore limb perfusion before definitive surgical treatment.
Procedure
Following successful revascularization, a Chopart amputation was performed, removing the forefoot together with part of the tarsal bones while preserving the hindfoot. The wound was intentionally left open and managed with secondary intention healing, allowing progressive granulation and epithelialization without primary closure.
Outcome
Complete wound healing was achieved after 5 months, preserving a functional weight-bearing hindfoot and avoiding a major below-knee amputation. This case demonstrates that even extensive ischemic gangrene extending into the midfoot does not necessarily require loss of the entire limb. When combined with successful revascularization, a Chopart amputation can provide durable limb salvage while maintaining meaningful function and independence.
