Hypoplasia of the thumb refers to a spectrum of clinical abnormalities ranging from a slightly small digit to complete absence (or aplasia) of the thumb unit. As a component of radial dysplasia, thumb hypoplasia can be either an isolated entity or seen in conjunction with other elements of radial longitudinal deficiency. Treatment of this condition initially involves identifying and addressing co-morbid anomalies in other body systems. The severity of thumb hypoplasia is then graded so that appropriate treatment methods can be instituted. The goal of treatment is ultimately to provide the child with a stable and functional thumb unit.
拇指发育不全指一系列临床异常情况，范围从拇指稍小到拇指单元完全缺失（或发育不全）。作为桡骨发育不良的一部分，拇指发育不全可以是一个孤立的病症，也可与桡骨纵向发育不全的其他因素同时出现。这种病症的治疗首先涉及识别和处理其他身体系统中的合并异常情况。然后对拇指发育不全的严重程度进行分级，以便能够制定适当的治疗方法。治疗的最终目标是为儿童提供一个稳定且功能正常的拇指单元。
