A 28-year-old man sustains a severe open injury to his forefoot. The toes and distal metatarsals cannot be salvaged, and the surgeon performs an amputation through the tarsometatarsal joints. What is this amputation called?

• A Chopart amputation
• B Boyd amputation
• C Pirogoff amputation
• D Lisfranc amputation ✓

Explanation

The Lisfranc amputation removes the forefoot through the tarsometatarsal joints, preserving the talus, calcaneum, navicular and cuboid. Chopart amputation is more proximal, through the midtarsal joints (talonavicular and calcaneocuboid), which kills option A. Pirogoff and Boyd are hindfoot amputations that retain part of the calcaneum fused to the tibia, used when the heel pad must be preserved.
