Arthrose de la cheville et de la sous-talienne

Most of the time, ankle and subtalar joint arthrosis are of traumatic origin. Tibiotalar arthrosis is well tolerated usually, except in some cases of malleolar surgical malunion which result in talar malrotation and extremely pathogenic joint incongruence. The most frequently used surgical technique is arthrodesis. This method has good results provided the peroperative position –radiologically controlled – has been determined very cautiously and provided the technique is adapted to anatomical lesions; in particular, adaptation must take into account the necessity of surgery extension to posterior subtalar joint, the key point of preoperative diagnosis. Prosthetic arthroplastic surgery (3^rd generation prostheses) is promising. It necessitates further validation by the retrospective analysis of surgical series in terms of implant survival. Isolated subtalar joint arthrosis may benefit from arthrodesis provided local anatomic damage and related impact on the overall foot architecture have been carefully analysed, aiming a surgical technique adapted to the anatomical situation.
