The therapeutic results of using a titanium alloy captured hip screw in cases of external fractures of the femoral neck were studied. The subjects were eight males and 22 females, a total of 30 with an average age of 78.8. According to Evans' classification, the fractures were the stable type in 21 cases and the unstable type in nine cases. The average operating time was 56 minutes and the average hemorrhagic volume was 80ml which were not inferior to those of other methods of osteosynthesis. Loading of the hip was started in the 3rd week postoperatively on the average, and bone union was confirmed after 10.5 weeks on the average in all cases. One case of protrusion of the lag screw in the joint and one case of breaking of the fixation material were observed as postoperative complications, but these were both technical errors, and it was considered that good results can be obtained if care is taken concerning reduction of the eversion position of the fracture, correct insertion of the lag screw and accurate joining of the hip screw and plate.
