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.
加压关节固定术可用于治疗关节病、硬皮病、活动过度关节、麻痹性畸形和类风湿性关节炎中的手指和拇指关节。在背侧做切口暴露关节。使用高速磨钻将关节面整修成球窝状排列。将一根直径1.1毫米的纵向钢针向远侧穿入，然后逆行穿入，以确定融合角度，并在施加纵向加压时防止骨端移位。将直径1.5毫米的横向钢针置于距关节三分之一距离处。应用经米克斯和哈格改良的查恩利夹并收紧。6周时，检查关节固定的牢固性，若稳定，则进行X线检查以观察新骨情况。当固定牢固时，关节应再用外部夹板固定2周，以确保融合完全。54个关节中有49个实现了加压关节固定。通常在6周内实现牢固融合，且其他关节无活动度丧失。
