Summary
Reverse shoulder arthroplasty (RSA) provides good mid-term outcomes for cuff tear arthropathy and omarthrosis, with low complication rates. This study confirms encouraging early results, demonstrating significant functional improvement and pain reduction after 5 years.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Rehabilitative Medicine
Background:
- Reverse shoulder arthroplasty (RSA) is a common treatment for cuff tear arthropathy, fracture sequelae, and omarthrosis with cuff insufficiency.
- Newer generation prostheses like the Delta Xtend have been used since 2007, but mid-term outcome data is limited.
Purpose of the Study:
- To report on the mid-term outcomes of RSA at a mean follow-up of 68 months.
- To verify previously published encouraging early results of RSA.
- To assess functional status and pain levels after RSA in the mid-term period.
Main Methods:
- 60 patients underwent RSA with the Depuy Delta Xtend prosthesis between 2007-2008.
- 39 patients completed the modified subjective Constant Score (msCS) questionnaire.
- 28 patients underwent clinical examination, including Constant Score, age/gender-adjusted Constant Score, and range of motion evaluation.
Main Results:
- Mean msCS improved from 39.15 preoperatively to 71.74 at 5 years.
- Mean Constant Score was 65.79, and the age/gender-adjusted Constant Score was 92% at 5 years.
- Mean active anterior elevation was 139°, abduction 135°, and external rotation 17°.
Conclusions:
- This study confirms good mid-term results for RSA, with outcomes extending beyond 5 years.
- Very good outcomes were observed in patients with cuff tear arthropathy and omarthrosis.
- The complication rate associated with RSA in this cohort was low.
