Treatment of Osteoporotic Unstable Intertrochanteric Fractures: Comparative Study between using Dynamic Hip Screw and Additional Trochanter Stabilizing Plate / 대한정형외과학회잡지

ABSTRACT

PURPOSE: To compare the effectiveness of a trochanter stabilizing plate with a dynamic hip screw, with using a dynamic hip screw only in the treatment of an unstable intertrochanteric fracture of elderly patients. MATERIALS AND METHODS: From January 2000 to December 2004, 70 patients, who were treated surgically for unstable intertrochanteric fractures, were evaluated. The patient s age were above 65 years and the T-score 0.05), but the postoperative functional loss of the hip joint was significantly lower in the group 2 (p<0.05), who required additional surgery due to reduction loss or metal failure. CONCLUSION: Although it is a relatively simple technique, the use of DHS with TSP is more effective for the buttress effect on proximal fragment and additional fixation of great trochanter than just DHS only. It decreases the excessive slippage of the lag screw, lateral displacement of the greater trochanter and postoperative functional loss of the hip joint. Therefore, it may be a useful treatment for unstable or comminuted intertrochanteric fractures in elderly patients with osteoporosis.
