We present short-term results of cementless total hip arthroplasties (THA) in the aged. 36 consecutive patients (38 hips) who underwent THA from March 1999 to December 2001 were enrolled in the study. The subjects were 80 years old or above, and the mean age was 84.0 years (range 80 to 95 years). There were 33 women and 3 men. Primary THA was 35 hips and revision THA was 3 hips. Preoperative diagnosis was 21 cases of osteoarthoritis, 5 rapidly destructive coxarthropathy, 9 fracture, and 3 necrosis of the femoral head. The mean follow-up period was 15 months (6 to 36 months). We evaluated clinical and roentgenographic results. Two patients had thigh pain. They started walking execises in postoperative 6.5 days. All cases were defined as bone ingrowth fixation. There were no roentogenographical loosening and sinking. We concluded that short-term results of cementless THA in the aged is an efficacious treatment.
