Title : Short-term clinical outcomes on a new dual-taper wedge femoral stem in total hip replacement
Abstract:
The use of dual-tapered stems in total hip arthroplasty is not a new concept, and its popularity in the direct-anterior total hip approach has increased. This study is a follow-up to a one that was presented last year, and analyzed the early clinical and radiological results of the Everglade stem (Signature Orthopedics NSW, Australia). A total of 100 patients (41 men and 59 women) were retrospectively studied and received 100 stems. The mean patient age was 68 years (interquartile range 62-76 years) at the time of surgery. The median follow-up was 317 days (up from 161.5 days) (interquartile range 169-408 days). The HOOS-Jr score improved from a mean 57.07 pre-operatively to a mean 86.03 at the 6-week visit and to 94.3 (up from 92.7) at the latest follow-up. At the one-year X-ray assessment, we observed no incidence of stem subsidence, peri-prosthetic fracture, or radiolucencies. There were no cases of osteolysis and no stems were revised. According to our results, this short, dual-tapered stem continues to show good short-term outcomes. Prospective studies with longer follow-up are needed to fully assess the long-term survivorship of this stem.
