ABSTRACT
PURPOSE:
This study was performed to evaluate the risk factors affecting the failure of fixation and to analyze the clinical and radiologic results after operation with using a sliding hip screw for treating OTA type A2 intertrochanteric fractures of the femur. MATERIALS ANDMETHODS:
From January 2001 to June 2005, we reviewed the clinical records and the serial radiographs of 53 patients (OTA type A2 intertrochanteric fractures of the femur) who were treated with a 135-degree angled sliding hip screw. We analyzed the change in the neck-shaft angle, the sliding distance and failure of the sliding screw, according to the reduction of the lesser trochanteric fragment and the stability of the lateral buttress.RESULTS:
Among 53 patients, there were 15 cases (28.3%) of failures to reduce the lesser trochanteric fragment. Losses of the lateral buttress were observed in 35 cases (66.0%). There were 8 cases (15.1%, 8/15) that failed radiologically, including cutting out of the sliding hip screw from a femoral head (3 cases), metal failure (1 case) and excessive sliding (4 cases). There were significantly differences for the changes of the angle of the neck-shaft, the distance of sliding and the length of penetration of the sliding hip screw, according to the reduction of the lesser trochanteric fragment and the stability of the lateral buttress.CONCLUSION:
It is important to consider the reduction of the lesser trochanteric fragment and the stability of lateral buttress when treating OTA type A2 intertrochanteric fractures with using a sliding hip screw.
