Silastic radial head prosthesis in rheumatoid arthritis

Area of Science:

• Orthopedic Surgery
• Rheumatology
• Biomaterials Science

Background:

• Rheumatoid arthritis frequently affects the elbow joint, causing pain and instability.
• Radial head involvement is common in rheumatoid arthritis, impacting joint function.
• Silastic radial head prostheses offer a potential solution for managing these debilitating symptoms.

Purpose of the Study:

• To evaluate the efficacy of Silastic radial head prostheses in treating rheumatoid arthritis of the elbow.
• To assess the outcomes of prosthesis implantation in both early and late stages of the disease.
• To determine the impact on pain relief and elbow joint stability.

Main Methods:

• Retrospective analysis of 18 patients with rheumatoid arthritis undergoing Silastic radial head prosthesis implantation.
• Categorization of cases based on disease severity and stage at the time of surgery.
• Follow-up assessment of pain, stability, and overall patient satisfaction.

Main Results:

• Early prosthesis replacement in 3 cases resulted in the best outcomes.
• 11 of the remaining 15 patients achieved satisfactory overall results.
• Significant pain relief was observed across all cases, including late-stage disease.
• Elbow stability was preserved in all but 3 cases.

Conclusions:

• Silastic radial head prostheses are a valuable treatment option for rheumatoid arthritis affecting the elbow.
• Timely intervention, particularly in early disease stages, maximizes functional recovery and patient satisfaction.
• The procedure effectively alleviates pain while maintaining joint stability, improving quality of life for affected individuals.
