IMHS clinical experience in the treatment of peritrochanteric fractures. The results of a multicentric Italian study of 981 cases

This retrospective study evaluates the results obtained in five Italian departments of traumatology in the treatment of peritrochanteric (pertrochanteric and subtrochanteric) fractures by the intramedullary hip screw (IMHS; Smith & Nephew Richards, Memphis, TN, USA) nail. One thousand two hundred and seventy-three patients were treated with the IMHS nail between March 1992 and February 2000. The results of these operations were evaluated clinically and radiological in 981 patients. The 90.3% of patients could walk unaided or with simple support. Because of the low complication rate requiring re-operation (postoperative shaft fractures, screw penetrated the acetabulum, cut out and non-union) (1.7%), we think that this device is an advance in the treatment of peritrochanteric fractures. © 2002 Elsevier Science Ltd.
