Deyerle treatment for femoral neck fractures.

Thirty-eight displaced intracapsular fractures of the femoral neck treated by the Deyerle method of internal fixation have been added to the previously reported series of sixty-three cases from the Walter Reed Army Medical Center Orthopaedic Service. A significant change in the incidence of non-union was found. In the over-all series of 101 patients, the incidence of non-union was 13.8 per cent and the incidence of segmental collapse due to avascular necrosis was 13.8 per cent. The roentgenographic and functional over-all end results were rated excellent in 67.7 per cent and poor in 32.3 per cent of the fractures. Some difficulties arising from the multiple-pin and plate technique and the associated morbidity are discussed. We now think that Deyerle method produces no better results than other methods of internal fixation of displaced intracapsular fractures.
