Thumb duplication is a complex congenital anomaly. Treatment requires a detailed understanding of the pathophysiology as well as an appreciation of all the components involved. The goals of surgery are to restore the normal anatomic relationships of the residual thumb. Successful reconstruction requires evaluation and correction of the bony axis; articular congruity; size and angulation; intrinsic and extrinsic musculotendinous abnormalities; and ligament, skin, and soft-tissue elements. The reconstructed thumb may not match the normal thumb because of the hypoplasia that is inherently associated with the condition. With careful preoperative planning and attention to detail, however, a satisfactory cosmetic and functional result can be achieved.
拇指重复畸形是一种复杂的先天性异常。治疗需要对病理生理学有详细的了解，并认识到所有涉及的组成部分。手术的目标是恢复残留拇指的正常解剖关系。成功的重建需要评估和纠正骨轴；关节一致性；大小和角度；内在和外在肌腱异常；以及韧带、皮肤和软组织成分。由于该病症固有的发育不全，重建的拇指可能与正常拇指不匹配。然而，通过仔细的术前规划和对细节的关注，可以获得令人满意的美容和功能效果。
