Survival of the Cementless Spotorno® Stem in the Second Decade

High survival rates have been reported for the uncemented CLS ® Spotorno ® stem up to 10 years. To confirm survival at longer followup we report the minimum 15-year (mean, 17 years; range, 15–20 years) for 257 hips using this stem. We retrospectively evaluated the clinical and radiographic results o...

Description
Summary:High survival rates have been reported for the uncemented CLS ® Spotorno ® stem up to 10 years. To confirm survival at longer followup we report the minimum 15-year (mean, 17 years; range, 15–20 years) for 257 hips using this stem. We retrospectively evaluated the clinical and radiographic results of all 326 patients (354 THAs) operated between 1985 and 1989. The patients had a mean age of 57 years using an uncemented grit-blasted, tapered titanium femoral stem. Eighty-six patients (89 hips) died and eight patients (eight hips) were lost to followup, leaving 240 patients (257 hips) for evaluation. The femoral component was revised in 35 hips: eight for infection, nine for periprosthetic fracture, one for traumatic loosening, and 17 for aseptic loosening. Survival of the stem was 88% at 17 years (95% confidence interval, 84%–92%), and survival with femoral revision for aseptic loosening as an end point was 94% (95% confidence interval, 91%–97%). The median Harris hip score at followup was 80 points. No thigh pain was reported. Small osteolytic lesions (
