Summary
Revision total hip arthroplasty (THA) effectively treats failed Austin Moore (AM) hemiarthroplasty in elderly patients, improving function and mobility. Avoid AM for active individuals, prioritizing THA for better long-term outcomes in femoral neck fractures.
Area of Science:
- Orthopedic Surgery
- Arthroplasty
- Geriatric Orthopedics
Background:
- Austin Moore (AM) hemiarthroplasty has limitations for elderly intracapsular femoral neck fractures, with high long-term failure rates.
- Revision total hip arthroplasty (THA) is considered for failed AM prostheses.
Purpose of the Study:
- To evaluate the functional outcomes and survivorship of revision THA after failed aseptic AM hemiarthroplasty.
- To assess intraoperative challenges during conversion from failed AM prosthesis to cemented THA.
Main Methods:
- A retrospective study of 89 cemented THA revisions for failed AM prostheses (1986-2005).
- Exclusion of infected failures; classification of AM failures into seven groups.
- Mean follow-up of 8 years (range 5-13 years) in 35 men and 54 women (mean age 68 years).
Main Results:
- Average Harris Hip Score improved significantly from 65 preoperatively to 87 at 1 year and 86 at final follow-up.
- Overall complication rate was low at 4.5%.
Conclusions:
- Conversion THA is an excellent strategy for symptomatic failed AM hemiarthroplasty, offering pain relief and functional restoration.
- Hemiarthroplasty is not recommended for physically active elderly patients.
- Careful patient selection between hemiarthroplasty and THA is crucial for optimizing outcomes in femoral neck fracture treatment.
