Compression arthrodesis of finger joints.

Compression arthrodesis is useful for treatment of finger and thumb joints in arthrosis, scleroderma, hypermobile joints, paralytic deformities, and rheumatoid arthritis. A dorsal incision exposes the joint. Its surfaces are prepared in a ball-and-socket arrangement using a high-speed burr. A longitudinal pin 1.1 mm in diameter is passed distally and then retrograde to determine the angle of fusion and to prevent migration of bone ends as the longitudinal compression is applied. Transverse pins 1.5 mm in diameter are put in one-third of the distance from the joint. A Charnley clamp, as modified by Micks and Hager, is applied and tightened. At 6 weeks, the arthrodesis is checked for solidity and, if stable, X-rays are examined for new bone. When solid, the joints should be protected by external splinting for an additional 2 weeks to be sure that the fusion is complete. Compression arthrodesis was obtained in 49 of 54 joints. Solid fusion was usually attained within 6 weeks, without loss of mobility of other joints.
