Abstract:
Cleft hand is an uncommon congenital malformation, which is defined as a deficiency of the central part of the hand. It results from the absence or alteration of development of the central rays. Although the function of the hand is often excellent, the cosmetic appearance drives parents to seek consultation. The goal of this article is to define the different factors that dictate the classification of this anomaly and to facilitate choosing among many surgical procedures. Treatment improves aesthetic aspect of the hand and maintains excellent function. A retrospective review of 33 operated cases is presented.
