Summary
Reverse shoulder arthroplasty shows low revision rates at 10 years but declining function and worsening X-ray results over time. Caution is advised for younger patients due to longevity concerns.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Reconstructive Surgery
Background:
- Reverse shoulder arthroplasty (RSA) use has surged since 1985.
- Early RSA outcomes show improved function and pain relief.
- Limited data exists on RSA durability and long-term results.
Purpose of the Study:
- Determine RSA complication rates.
- Evaluate functional scores and survivorship over time.
- Assess radiographic signs of loosening.
Main Methods:
- Retrospective review of 527 RSAs (1985-2003).
- Clinical and radiographic assessment with minimum 2-year and 5-year follow-up.
- Survival analysis using prosthesis revision and Constant-Murley score < 30 as endpoints.
Main Results:
- 107 complications in 89/489 patients.
- 10-year revision-free survival was 89%; notable decline at 2 and 9 years.
- 10-year survival with Constant-Murley score < 30 was 72%; notable decline at 8 years.
- Progressive radiographic changes and increased notching observed after 5 years.
Conclusions:
- RSA revision rates are relatively low at 10 years.
- Functional scores and radiographic findings deteriorate over time.
- Longevity concerns necessitate caution, especially for younger patients.
