Trochanteric-sparing Proximal Femoral Resection for Arthritic Spastic Hips

Progressive hip subluxation or dislocation leading to degenerative disease, in neuromuscular disease, is a significant cause of morbidity to the patient and burden to the caretaker. Surgical salvage procedures have unpredictable success. We hypothesized that modifying the Castle-type proximal femoral resection by securing a retained greater trochanter with its musculature to the capsular arthroplasty and femoral shaft would compartmentalize the femur to decrease proximal femoral migration and heterotopic ossification (HO), thereby precluding the need for traction and HO prophylaxis while improving pain and caretaker satisfaction. The purpose of this report is to describe the novel trochanteric-sparing proximal femoral resection (TS-PFR) technique. Seventeen hips in 13 patients were treated by the TS-PFR procedure. Twelve of 13 patients experienced complete pain relief, and all had improved sitting tolerance and perineal care. These results represent an improvement from prior salvage operations, without increase in blood loss, length of stay, proximal femoral migration, or HO. One patient underwent revision for failed soft tissue envelope. A retrospective review of patients treated at 2 institutions identified those who underwent TS-PFR for arthritic spastic hip. Perioperative course, radiologic evaluation for migration and HO, and caretaker satisfaction were compared with prior published surgical techniques. The TS-PFR technique is a safe alternative to previously described s...
