Summary
Hip replacement is a safe salvage option for proximal femur fixation failure. Total hip arthroplasty (THA) yielded better outcomes than hemiarthroplasty (HA), though careful patient evaluation is crucial.
Area of Science:
- Orthopedic Surgery
- Reconstructive Surgery
Background:
- Proximal femur fixation failure presents a rare but significant clinical challenge.
- Hip replacement surgery is considered a potential salvage treatment for these complex cases.
- While effective, hip replacement can be associated with serious complications.
Purpose of the Study:
- To retrospectively evaluate hip replacement outcomes following proximal femur fixation failure.
- To assess both functional and radiographic results of salvage hip arthroplasty.
Main Methods:
- Review of Total Hip Arthroplasty (THA) and Hemiarthroplasty (HA) cases from 2013-2020.
- Radiographic assessment included stem subsidence, alignment, limb length discrepancy, and heterotopic ossification.
- Functional outcomes were measured using Harris Hip Score (HHS) and Hip WOMAC score.
Main Results:
- 14 THA cases showed no complications, with high mean HHS (86.5) and WOMAC (91.68) scores.
- One THA case of periprosthetic infection was successfully managed with two-stage revision.
- 5 HA cases had lower mean HHS (65.8) and WOMAC (70.18) scores, with two dislocations requiring revision to THA.
Conclusions:
- Hip replacement serves as a safe and recommendable salvage procedure for proximal femur fixation failure.
- Total hip arthroplasty demonstrated superior functional and radiographic outcomes compared to hemiarthroplasty.
- Preoperative patient assessment is vital to identify and mitigate potential complication risks.
