Abstract

The long-term survival of the cementless Spotorno (CLS) femoral component (Zimmer Inc, Warsaw, USA) was evaluated in a consecutive series of 85 patients (100 hips) less than 50 years of age. The mean follow-up was 12.3 years. Two patients (3 hips) were lost to follow-up, and 3 (4 hips) died. The survival rate of the CLS stem was 96.9% (confidence interval [CI], 93.6%-100%) after 13 years based on revision of the stem for any reason. The survival of the stem with revision for aseptic loosening as the end point was 97.9% (CI, 95.1%-100%) at 13 years. The mean Harris hip score at time of follow-up was 94. The long-term survival of the CLS stem is excellent in patients less than 50 years of age.
