This study reviews outcomes of patients undergoing Wilson extension osteotomy of the first metacarpal for treatment of carpometacarpal (CMC) joint pain and deformity. The study reviews varied indications for Wilson osteotomy outlining technique and functional outcomes. Twelve patients (11 female, 1 male) with an average age at surgery of 50 (range, 25-67) underwent osteotomy during the study period. Diagnoses included seven patients with early degenerative changes of the CMC joint with painful subluxation or instability. The remaining patients had symptomatic adduction contracture in either end-stage arthritis (three) or following prior trapeziectomy (two). Average motion improved modestly among all groups with considerable improvement of metacarpophalangeal hyperextension in late deformity patients. Wilson osteotomy is a motion-preserving alternative procedure that may be indicated for patients with early CMC arthrosis and instability as well as for patients with adduction contractures in end-stage arthritis or posttrapeziectomy (Journal of Surgical Orthopaedic Advances 28(1):63-67, 2019).
本研究回顾了接受第一掌骨Wilson延长截骨术治疗腕掌关节（CMC）疼痛和畸形患者的治疗结果。该研究回顾了Wilson截骨术的不同适应症，概述了技术和功能结果。在研究期间，12例患者（11例女性，1例男性）接受了截骨术，手术时的平均年龄为50岁（范围25 - 67岁）。诊断包括7例CMC关节早期退变伴疼痛性半脱位或不稳定的患者。其余患者在终末期关节炎（3例）或先前的大多角骨切除术后（2例）出现有症状的内收挛缩。所有组的平均活动度均有适度改善，晚期畸形患者的掌指关节过伸有显著改善。Wilson截骨术是一种保留活动度的替代手术，适用于早期CMC关节病和不稳定的患者，以及终末期关节炎或大多角骨切除术后出现内收挛缩的患者（《外科骨科进展杂志》28(1):63 - 67, 2019）。
