Thumb hypoplasia is part of a spectrum of radial longitudinal deficiencies involving the upper limb. Systemic involvement of other organ systems is not uncommon, thus requiring a team approach to management. Because of the variety of anatomic abnormalities associated with thumb hypoplasia, clinical and intraoperative evaluation of the thumb must be precise. Effective management of thumb hypoplasia requires an understanding of the embryology, epidemiology, classification, presentation, and management options. Management, which is primarily determined by the grade of thumb hypoplasia, may include nonsurgical techniques, reconstruction, pollicization, and, recently, microsurgical procedures.
拇指发育不全是涉及上肢的桡侧纵向发育缺陷谱系的一部分。其他器官系统的全身性受累并不罕见，因此需要团队协作进行管理。由于与拇指发育不全相关的解剖学异常多种多样，对拇指的临床和术中评估必须精确。有效的拇指发育不全管理需要了解其胚胎学、流行病学、分类、表现及管理选项。管理主要由拇指发育不全的分级决定，可能包括非手术技术、重建、拇指再造，以及最近的显微外科手术。
