Treatment of Subtrochanteric Fractures with Compression Hip Screw

ABSTRACT

PURPOSE: To evaluate the effectiveness of the compression hip screw, we reviewed the clinical results of cases of femoral subtrochanteric fracture which were treated with compression hip screw. MATERIALS AND METHODS: From May 1997 to June 2004, 20 cases of femoral subtrochanteric fracture, which were treated with compression hip screw and followed up more than 12 months, were reviewed. By the Seinsheimer's classification, there were 1 case of type IIa, 4 cases of type IIb, 2 cases of type IIIa and IIIb, 4 cases of type IV and 7 cases of V. We analyzed the treatment results by bony union time, range of motion, ambulation status and complications. RESULTS: All 20 cases were gained bony union without serious complications and secondary operation. The average bony union time was 19.8 weeks. 17 of 20 cases were recovered pre-injury ambulatory status level. CONCLUSION: The compression hip screw may be effective in treatment of the femoral subtrochanteric fracture with very narrow intramedullary canal, proximal femoral deformity, comminuted fracture with large butterfly fragment, long spiral fracture with medial cortical comminution and combined intertrochanteric fracture.
