The femur fracture after hip arthroplasty(0.1-3.2%) is a well-known complication. According to the previous reports, it is more frequently observed in noncemented arthroplasty of the hip As the causes of these fractures, tight fixation of the
femoral
stem, design problem of femoral stem and design of femoral stem and anatomical configuration of the femur should be considered.
Among 600 cases, who were treated by hip arthroplasty from Dec. 1984 to Dec. 1995, the 42 cases of the 38 patients of the femoral fractures were evaluated. The authors tried to make new classification and fine out the best reported treatment
methods.
The authors classified intraop0erative or postoperative or postoperative femoral fractures
according to the location and type. The most common type was A(proximal, 64%). We
recommend more than 8 hole plate and bone graftin stable prosthesis. In unstabie prosthesis,
we recommend longer stem for the treatment of fracture.
