Tibiotalocalcaneal Arthrodesis as a Tool for Podoplastic Limb and Gait Salvage in the Chopart Amputation: A Functional Assessment.

The Chopart amputation is a controversial amputation level and has been described as a relatively non-functional amputation due to the increased risk for stump deformity and subsequent complications. Recent literature has shown that a tibiotalocalcaneal arthrodesis can subjectively increase function in the Chopart amputation. We describe the use of a tibiotalocalcaneal arthrodesis in a 44-year-old diabetic male with a Chopart amputation for the purpose of limb and gait salvage. After 292 days and an uneventful postoperative course, the patient consented to gait analysis. The case allows us to objectively conclude that the tibiotalocalcaneal arthrodesis can quantitatively increase the functionality of the Chopart amputation and, in turn, expand its indication for use within the more functional populations.
