目的通过半关节移植修复缺如的指间关节近端关节面及侧副韧带,重建重复拇指畸形患者严重偏斜的指间关节。方法1994年3月—2002年11月间,对7例患者利用赘生拇指近节指骨的近端关节面及部分关节囊,行一期或二期半关节移植,重建保留拇指的指间关节近端发育不良或缺如的关节面。术后随访3年,观察骨关节生长及功能恢复情况。结果移植的半关节大部存活,85%患者的骨外形良好、功能恢复较满意。结论半关节移植是治疗重复拇指畸形伴指间关节严重发育不良的一种可行的手术方法。
Objective To repair severely skewed interphalangeal joints of patients with repeated thumb deformity by means of hemiarticular transplantation to repair the missing proximal interphalangeal articular surface and collateral ligaments of the interphalangeal joint. Methods From March 1994 to November 2002, 7 patients underwent primary or secondary hemiarthroplasty using the proximal articular surface of the proximal phalanx phalanx of the neoplasm and part of the joint capsule to reconstruct the interphalangeal joint Proximal dysplasia or absence of articular surface. After 3 years of follow-up, bone and joint growth and functional recovery were observed. Results Most of the transplanted hemi-articular joints survived, and 85% of the patients had good bone appearance and satisfactory functional recovery. Conclusion Hemiarticular transplantation is a feasible surgical method for the treatment of severe dysplasia of the thumb deformity and interphalangeal joint.
