Fracture of the femoral prosthesis after total hip replacement

Although fracture of the femoral component is a well‐known complication of total hip replacement, especially with the earlier types of prosthesis, it is seldom recognized in its initial stages. A series of 22 fractures of the femoral component of the prosthesis in 19 patients is presented for the benefit of the general practitioner and the radiologist, who, it is stressed, should both be aware of this complication and able to recognize the signs of a possible fracture, so that early treatment may be given to avoid excessive bone loss in the upper femur. The clinical features are described and discussed.
