Summary
Capitellocondylar elbow arthroplasty offers significant pain relief and improved motion for rheumatoid arthritis patients. Despite potential complications, this surgical procedure demonstrates high success rates in carefully selected individuals.
Area of Science:
- Orthopedic Surgery
- Rheumatology
- Biomedical Engineering
Background:
- Rheumatoid arthritis frequently causes severe elbow joint destruction and intractable pain.
- Nonconstrained elbow arthroplasty is an option for managing end-stage rheumatoid arthritis of the elbow.
Purpose of the Study:
- To evaluate the clinical outcomes of nonconstrained capitellocondylar elbow arthroplasty in patients with rheumatoid arthritis.
- To assess pain relief, functional improvement, and complication rates following the procedure.
Main Methods:
- Twenty-eight nonconstrained capitellocondylar elbow arthroplasties were performed in 23 patients with rheumatoid arthritis.
- Patients were evaluated postoperatively using the Ewald scoring system at an average of 35 months.
Main Results:
- Eighty-six percent (24/28) of procedures had satisfactory outcomes.
- Significant improvements in pain relief and range of motion were observed (average arc increased from 88 to 101 degrees).
- Complications included four dislocations (one requiring revision) and two remote infections; one case of loosening was noted.
Conclusions:
- Nonconstrained capitellocondylar elbow arthroplasty provides predictable success and substantial functional gains for select rheumatoid arthritis patients.
- While complications can occur, the benefits of pain reduction and improved function often outweigh the risks in properly selected cases.
