Fixation Failure after internal Fixation in Intertrochanteric Fractures

Abstract

Fixation failure is a major complication of intertrochanteric fracture. The causes of fixation failure were assessed in a series of 80 patients with intertrochanteric fractures, which had been internally fixed with either a sliding hip screw or a Gamma interlocking nail. The overall rate of fixation failure was 16.3%, in which the cutting-out of the implant from the femoral head was the only cause of the instance. The cutting-out rate was influenced by the accuracy of fracture reduction, the position of implant placement within the femoral head, and the bone mineral density. Anatomical reduction and the central placement of implant within the femoral head showed the most excellent results compared to other treatment modalities. Age, gender, fracture type and a kind of fixation implant had no significant effect. Our results showed that the intertrochanteric fractures should be reduced as anatomically as possible and it is essential that the central placement of the implant within the femoral head be obtained.
