Common Congenital Hand Differences
Congenital differences of the hand are common in a pediatric hand surgery practice. The child’s global health and genetic counseling should be addressed before focusing on the upper limb disorder. Appropriate referral is necessary to facilitate education about the congenital difference and its effect on subsequent generations. The physician must be comfortable and have a sound understanding of the diagnosis and treatment algorithm. Reoperation rates are high for even the most common congenital hand defects treated by experienced surgeons. Syndactyly, polydactyly, thumb hypoplasia, and symbrachydactyly are particularly commonplace and are discussed in this review. The main aim when treating these disorders is improving hand function; however, aesthetics must also be considered when planning surgery.
