The aim of the study was clinical and X-ray evaluation of two patients treated because of fractures of shaft of femur with coexisting hip joint osteoarthritis with cemented THR. Both patients were treated just after the injury. Reduction of fractures were made to both patients. Stabilization of fracture in one patient was made with metal plate and cables, stabilization with only cables was made to second patient. Exeter THR with standard stem was implanted to first patient, and with long stem to the second one. Both patients have good clinical results - 90 and 92 pts. in Harris Hip Score after 36 and 48 months accordingly. The fracture healed in the first patient. The evidence of fracture healing of the second patient was impossible to examine because of lack of X-ray. Conclusions. 1) The use of THR in the treatment of femoral shaft fractures with coexisting osteoarthritis gives a chance of simultaneous fracture treatment and joint replacement. 2) Fracture stabilization requires the use of metal plates and cables.
