Treatment of longitudinal deficiency affecting the femur: comparing patient mobility and satisfaction outcomes of Syme amputation against extension prosthesis.

Patients with proximal focal femoral deficiency or longitudinal deficiency affecting the femur were selected from a large regional center. Twenty-eight such patients were identified and were divided into two groups depending on how their condition was managed. Group 1 had opted for the surgical approach of ankle disarticulation (Syme amputation) and the fitting of an above-the-knee prosthesis.
