In nine years 26 duplicated thumbs were seen in the hand clinic of a hospital for crippled children. Using a classification based on the level and degree of duplication and a knowledge of the abnormal anatomy, reconstruction was done. This surgery was done with proper skin incisions, reconstructions of the collateral ligaments, centralization of the flexor and extensor tendons, and alignment of the bones and joints by corrective osteotomies. Simple ablation or incomplete correction produced complications such as skin contractures, increased angular deformities, unstable joints, and intrinsic weakness. In all of the patients, the appearance was improved, opposition was maintained, and postoperative function was not impaired.
在九年时间里，一家残疾儿童医院的手部诊所共接诊了26例重复拇指畸形病例。依据重复的水平和程度分类以及异常解剖结构的知识进行了重建手术。该手术通过适当的皮肤切口、侧副韧带重建、屈指肌腱和伸指肌腱的中心化以及通过截骨矫正术使骨骼和关节对线来完成。单纯切除或不完全矫正会引发诸如皮肤挛缩、角畸形加重、关节不稳定和内在肌无力等并发症。所有患者的外观均得到改善，对掌功能得以保留，且术后功能未受损害。
