Surgical interventions for the rheumatoid shoulder

Area of Science:

• Orthopedics
• Rheumatology
• Surgical Innovation

Background:

• Rheumatoid arthritis (RA) frequently causes severe glenohumeral joint destruction.
• Conservative treatments for RA shoulder involvement often yield insufficient results.
• Surgical intervention is considered when non-operative management fails.

Purpose of the Study:

• To evaluate the beneficial and harmful effects of all surgical treatments for shoulder management in rheumatoid arthritis (RA) patients.
• To synthesize evidence from randomized controlled trials (RCTs) and other study designs on shoulder surgery outcomes in RA.

Main Methods:

• Comprehensive literature search conducted across multiple databases (Cochrane, MEDLINE, EMBASE, SCISEARCH) from January 1995 to May 2008.
• Inclusion criteria focused on Randomized Controlled Trials (RCTs), Controlled Clinical Trials (CCTs), and case series assessing shoulder surgery outcomes and complications in RA.
• Data extraction and quality assessment were performed independently by two review authors.

Main Results:

• One RCT comparing cemented vs. uncemented humeral stem fixation in arthroplasty showed no significant difference after two years (low-quality evidence).
• One CCT indicated augmented subscapularis transposition improved function and pain more than subscapularis transposition alone after two years (low-quality evidence).
• Complication rates were 11% for total shoulder arthroplasties and 9.9% for hemiarthroplasties, based on case series data (very low-quality evidence).

Conclusions:

• The evidence base for surgical treatment of the rheumatoid arthritis (RA) shoulder is significantly limited.
• A paucity of high-quality randomized controlled trials hinders definitive conclusions on the efficacy and safety of shoulder surgery in RA.
• Further rigorous research is needed to guide surgical management decisions for RA patients with shoulder involvement.
