Long-term (20-to 25-year) results of an uncemented tapered titanium femoral component and factors affecting survivorship
MR Streit, MM Innmann, C Merle… - Clinical Orthopaedics …, 2013 - journals.lww.com
Background Uncemented femoral components in primary total hip arthroplasty (THA) are
commonly used today, but few studies have evaluated their survival into the third decade.
Questions/purposes We evaluated (1) survivorship using femoral revision for any reason as
the end point;(2) survivorship using femoral revision for aseptic loosening as the end point;
and (3) patient-related and surgical risk factors for aseptic stem loosening at a minimum 20-
year followup with an uncemented tapered titanium stem. Methods We reviewed the clinical …

LONG-TERM (20 TO 25 YEAR) RESULTS OF AN UNCEMENTED TAPERED FEMORAL STEM IN PRIMARY TOTAL HIP ARTHROPLASTY

Introduction: High survival rates have been reported for the uncemented CLS Spotorno stem
up to 20 years. To confirm survival at longer follow-up we report the minimum 20-year
(mean, 22 years; range, 20–25 years) results using this device. Methods: We retrospectively
evaluated the clinical and radiographic results of a consecutive series of 354 total hip
arthroplasties using an uncemented grit-blasted, tapered femoral stem (CLS Spotorno) in
326 patients. Mean time of follow-up evaluation was 22 years (range, 20–25 years), mean …
