Thumb duplication is a common congenital abnormality accounting for 6.6% of all hand deformities. The object of the primary surgery is to achieve a thumb with aligned joint surfaces and epiphyses perpendicular to the long axis, central flexor and extensor tendons, and adequate collateral ligaments. Experienced surgeons with an understanding of the abnormal anatomy and knowledge of the numerous refinements in technique cannot guarantee a flawless result. Of 43 cases treated in this Unit during the period 1970-1989 49% were noted to have secondary deformities. Angulation at the IP and/or MP joints were the most commonly observed problems. Unsatisfactory results were seen with a greater frequency following correction of the more complex deformities.
多指畸形是一种常见的先天性异常，占所有手部畸形的6.6%。一期手术的目的是使拇指的关节面和骨骺与长轴垂直对齐，屈指肌腱和伸指肌腱位于中央，侧副韧带充分。经验丰富且了解异常解剖结构以及掌握众多技术改进知识的外科医生也不能保证获得完美的结果。在本单位1970年至1989年期间治疗的43例病例中，49%被发现有继发畸形。指间关节和/或掌指关节的成角是最常见的问题。在矫正更复杂的畸形后，不满意的结果出现的频率更高。
