Purpose: The purpose of this study is to evaluate the clinical and radiological results of the trochanteric flip osteotomy in cases of femoral head fractures.
Materials and Methods: Between May 2000 and January 2012, we evaluated 14 cases of femoral head fractures treated by trochanteric flip osteotomy in combination with the Kocher-Langenbeck approach after a minimum follow-up of one year. There were 13 men and one woman and the average follow-up period was 36.4 months. The clinical results were evaluated according to Merle d’Aubigne-Postel scores and the Thompson-Epstein scoring scale and the radiological results were evaluated according to time to union of fractures and osteotomy site. We also evaluated the incidence of complications.
Results: At the last follow-up, mean Merle d’Aubigne-Postel score was 16.4 and 11 cases out of 14 patients presented with good to excellent, two cases presented with fair, and one case presented with a poor clinical result according to the Thompson-Epstein scoring scale. Radiologically all cases achieved union of fractures and osteotomy site and the mean time to union of the osteotomy site was 7.9 weeks. Complications included one case of heterotopic ossification which did not disturb hip function, two cases of avascular necrosis of the femoral head, and one case of post-traumatic osteoarthritis.
Conclusion: The trochanteric flip osteotomy in the case of a femoral head fracture showed good clinical and radiological results through good visualization and accurate reduction of the fracture site. However, conduct of further studies including larger number of patients is needed in order to evaluate the incidence of complications such as avascular necrosis of the femoral head.
