Lisfranc and Chopart amputations.

The issue of choosing an amputation level can be difficult for physicians. Every attempt should be made to maintain as much pedal length as possible to increase biomechanical function and ambulatory power. When there is excessive soft tissue loss because of trauma, infection, or vascular compromise, a Lisfranc amputation should be considered as a limb-salvage procedure. A more proximal midfoot amputation than Lisfranc is one at Chopart's articulation. This article addresses Lisfranc and Chopart amputations.
