Fifty-four supernumerary thumbs excisions were followed for an average of 9 years for results of their surgical management, which consisted of simple excision (16 patients), reconstructive procedures (33 patients), or central wedge resections (5 patients). Half of all simple excisions and reconstructive procedures gave unacceptable results, most were salvaged. These were primarily joint deviations, joint instabilities, and bony prominences. All of our central wedge resections gave unacceptable results that were not salvageable--short, stiff, fat thumbs with nail deformities. We feel this procedure should probably be reserved for cases where both digits of the supernumerary thumbs are severely hypoplastic.
对54例多指拇指切除术的手术治疗结果进行了平均9年的随访，手术方式包括单纯切除术（16例患者）、重建手术（33例患者）或中央楔形切除术（5例患者）。所有单纯切除术和重建手术中有一半的结果不理想，大多数情况得以挽救。主要问题是关节偏斜、关节不稳定和骨突出。我们所有的中央楔形切除术结果都不理想且无法挽救——拇指短粗、僵硬，伴有指甲畸形。我们认为该手术可能应仅用于多指拇指的两个指体均严重发育不全的病例。
