Revision total hip arthroplasty using a tapered, press-fit cementless revision stem in elderly patients.

摘要

In elderly patients, osteoporosis can complicate revision total hip arthroplasty (THA). The SLR-Plus (Smith & Nephew, Memphis, TN) revision stem has a tapered, press-fit design, which we hypothesized could enhance stability in this population. Accordingly, we retrospectively analyzed data for 48 elderly patients who underwent revision THA using the SLR-Plus stem. The patients had a mean age of 66.5 years (range, 60-81 years) at surgery. They were monitored for a mean of 5.6 years (range, 3.4-8.0 years) after surgery. The mean Harris Hip Score improved from 67.8 to 91.6. No infection, dislocation, osteolysis, or stress shielding around stem were observed after surgery. The survivorship at an average of 5.6-year follow-up was 98%. These favorable results indicate that the SLR-Plus stem is useful in revision THA in elderly patients.
