The purpose of surgery for polydactyly of the thumb is to ablate the supernumerary digit and to reconstruct a thumb with adequate function that approximates normal size and shape. A further aim is to prevent the occurrence of deformity in the future. To achieve these goals, one good thumb is reconstructed using portions from the supernumerary digit as follows: To increase the diameter of the reconstructed thumb, a skin flap is formed from the supernumerary digit. A portion of the joint from the supernumerary digit is used to correct joint deviation in the reconstructed thumb. The collateral ligament and abductor muscle are detached from the supernumerary digit with the bone fragment into which they are inserted, and transplanted together with the bone fragment into the reconstructed thumb. Osseous tissue to be used in open wedge osteotomy to correct longitudinal deviation is obtained from the phalanx of the supernumerary digit.
拇指多指畸形手术的目的是切除多余手指，并重建一个功能良好、大小和形状接近正常的拇指。另一个目的是预防未来畸形的发生。为实现这些目标，利用多余手指的部分组织重建一个良好的拇指，具体如下：为增加重建拇指的直径，从多余手指形成一个皮瓣。多余手指的一部分关节用于矫正重建拇指的关节偏斜。将侧副韧带和外展肌与其插入的骨块一起从多余手指上分离，并与骨块一同移植到重建拇指中。用于开放楔形截骨术矫正纵向偏斜的骨组织取自多余手指的指骨。
