Polydactyly: a review

Bull Hosp Jt Dis (2013). 2013;71(1):17-23.


Polydactyly of the hand is a difficult problem and poses a unique challenge for the hand surgeon. The embryology of limb development is complex, leading to a host of different phenotypes of polydactyly. Polydactyly can occur in any digit and is described as preaxial, postaxial, and central, based on location. Classification systems exist for each of these locations, which guide treatment options. Surgical treatment needs to address the aesthetic and functional aspect of hand reconstruction. Careful consideration and planning of surgical treatment individualized to each patient is required to obtain the best possible outcome.
