We report a long-term follow-up of abduction-extension osteotomy of the first metacarpal, performed for painful trapeziometacarpal osteoarthritis. Of a consecutive series of 50 operations, 41 thumbs (82%) were reviewed at a mean follow-up of 6.8 years. Good or excellent pain relief was achieved in 80%, and 93% considered that surgery had improved hand function, while 82% had normal grip and pinch strength, with restoration of thumb abduction. Metacarpal osteotomy was equally successful in relieving symptoms of those with early (grade 2) and moderate (grade 3) degenerative changes. This simple procedure provides lasting pain relief, corrects adduction contracture and restores grip and pinch strength, giving good results with few complications.
我们报告了针对疼痛性大多角骨-第一掌骨关节炎而施行的第一掌骨外展-伸展截骨术的长期随访结果。在连续的50例手术中，对41例拇指（82%）进行了平均6.8年的随访。80%的患者疼痛得到了良好或极好的缓解，93%的患者认为手术改善了手部功能，82%的患者握力和捏力正常，拇指外展功能得以恢复。掌骨截骨术对于早期（2级）和中度（3级）退行性改变患者的症状缓解同样成功。这种简单的手术能提供持久的疼痛缓解，纠正内收挛缩，恢复握力和捏力，效果良好且并发症少。
