Silastic arthroplasty in rheumatoid MCP-joints

Abstract

Resection arthroplasty using Swanson silicone prosthesis was performed in 74 MCP-joints in 22 patients, all with rheumatoid arthritis. Follow-up at 2 (1-7) years showed complete pain relief in 15 patients and considerable improvement in hand function; the average range of motion was unchanged but extension was improved and ulnar deviation and volar displacement were reduced. Complications included fracture of four implants, two superficial infections, one hematoma and one skin necrosis.
