Summary
Swanson silicone prosthesis for rheumatoid arthritis in MCP-joints provided pain relief and improved hand function for many patients. While range of motion was unchanged, extension improved, and deformities were reduced.
Area of Science:
- Orthopedic Surgery
- Rheumatology
- Biomaterials Science
Background:
- Rheumatoid arthritis commonly affects metacarpophalangeal (MCP) joints, leading to pain and functional impairment.
- Surgical interventions are often necessary to manage advanced rheumatoid arthritis of the hand.
Purpose of the Study:
- To evaluate the efficacy and complications of resection arthroplasty using Swanson silicone prosthesis in MCP-joints of patients with rheumatoid arthritis.
Main Methods:
- Seventy-four MCP-joints in 22 patients diagnosed with rheumatoid arthritis underwent resection arthroplasty with Swanson silicone prostheses.
- Patients were followed up for a mean duration of 2 years (range 1-7 years).
Main Results:
- Complete pain relief was reported by 15 patients, with considerable improvement in hand function observed.
- Average range of motion remained unchanged; however, extension improved, and ulnar deviation and volar displacement were reduced.
- Complications included four implant fractures, two superficial infections, one hematoma, and one instance of skin necrosis.
Conclusions:
- Resection arthroplasty with Swanson silicone prostheses can effectively alleviate pain and improve hand function in rheumatoid arthritis patients.
- While generally successful, potential complications such as implant fracture and infection require careful consideration and monitoring.
