[Osteotomy to lengthen the femur neck with distal adjustment of the trochanter major in coxa vara after hip dislocation].

Hip dysplasia and treated dislocations of the hip can lead to deformity of the proximal femur with shortening of the femoral neck and proximal displacement of the greater trochanter. Shortening the femoral neck causes a reduction in the leg length and insufficient performance of the abductors in the hip. Furthermore, the mechanical axis of the knee joint is lateralized. We used a technique involving lengthening the femoral neck and distal transfer of the greater trochanter to restore the normal anatomy and normal biomechanics of the hip joint. We used three osteotomies: one at the greater trochanter, one at the proximal, and the third an oblique osteotomy at the level of the distal femoral neck. In our group of 15 patients with 16 operated hip joints, the results were satisfactory in 14 of the 16 hips. This technique is recommended in young patients with little or no degenerative changes.
