We treated thirty-six patients (thirty-eight thumbs) who had residual deformity after ablation of a duplicated thumb. The deformities were classified into three groups: interphalangeal (eight thumbs), metacarpophalangeal (sixteen thumbs), and zigzag (fourteen thumbs). The indication for operation was primarily cosmetic; only eight patients had a functional disability, and that was mild. At the most recent follow-up, the results were rated good except for three fair results in the group that had an interphalangeal deformity, two fair results in the group that had a metacarpophalangeal deformity, and two poor and seven fair results in the group that had a zigzag deformity.
我们治疗了36例（38根拇指）在重复拇指切除术后仍有残留畸形的患者。畸形分为三组：指间关节（8根拇指）、掌指关节（16根拇指）和锯齿状（14根拇指）。手术指征主要是美容方面的；只有8例患者有功能障碍，且程度较轻。在最近的随访中，除了指间关节畸形组有3例结果为一般、掌指关节畸形组有2例结果为一般、锯齿状畸形组有2例结果为差和7例结果为一般外，其余结果均评为良好。
