From 1991 to 1994, we performed 31 cementless total hip arthroplasties in 30 patients. Of these we were able to follow 15 joints in 15 patients for more than one year. From these 15 total hip arthroplasties, we assessed roentgenologic criteria on the stem side. According to the assessment, there were two “unstable” stems and it seemed important to get cancellous condensation in the proximal femur.
