[Cephalic prostheses in femoral neck fractures: Comparison of immediate complications and late functional results of Moore's prosthesis and sealed prosthesis].

In this study the authors compared the mortality of fractures of the neck of the femur treated by femoral prostheses with early walking compared with trochanteric fractures treated by a nail plate and non-weight bearing activity for 2 to 3 months. The mortality in the two series (about 20 per cent) was the same. The authors then compared two series of fractures of the femoral neck, one treated by Moore's prosthesis without cement and the other by an alternative type of femoral prosthesis with cement. They conclude that the mortality was the same in the two groups but that the cemented prosthesis had better functionnal results. Long-term tolerance of the acetabulum was the same in the two types of prosthesis. Total hip replacement is very rarely indicated in recent fractures of the femoral neck.
