Shortening subtrochanteric osteotomy of the femur in total hip arthroplasty in patients with congenital hip dislocation
Congenital hip dislocation in adults (Crowe type IV) is an indication for hip replacement. Shortening subtrochanteric osteotomy of the femur reduces the risk of vascular and neurological complications and corrects the antetorsion of the proximal femur. Purpose To demonstrate our experience with the use of the method of shortening osteotomy of the femur in hip joint replacement for congenital hip dislocation with an assessment of postoperative complications. Materials and methods 64 hip arthroplasties were performed using corrective osteotomy. The follow-up period was from 6 months to 8 years. We evaluated pain and functional status according to VAS and Harris Hip Score. Results Pain according to VAS in the hip was 3.4 ± 1.1 and 2.1 ± 2.2 in the lumbar spine. HHS was 55.6 ± 17.2 points. Pain relief in the lumbar spine might be associated with changes in the lateral radiographs of the lumbar spine. In the postoperative period, pelvic anteversion returned to normal, as did the other angles of the lumbar-pelvic balance. Conclusions Hip joint arthroplasty for Crowe type IV hip dysplasia is an operation of high complexity and is associated with a high risk of complications (19.7 %).
