A Functional Chopart's Amputation With Tendon Transfers.

Generally, forefoot osteomyelitis is treated with a reliable level of amputation such as at the transmetatarsal level. However, when osteomyelitis extends proximal to the midfoot and presents with significant peripheral arterial disease, it is generally thought that the next best functional level of amputation is a transtibial amputation. This is mostly in part due to the high failure rate of Chopart's amputations which can be attributed to poor biomechanical and tendon balancing.
