Segmental digital transposition in congenital hand deformities.

A review of the current management of congenital digital hypoplasia in the hand has been presented. Techniques for augmenting the size and length of hypoplastic digits have included flap and graft techniques and segmental digital transposition techniques; they now include digital distraction lengthening techniques and free vascularized digital transposition techniques. Since all of these methods are still in use, the relationship between them has been described and some of the lesser known segmental digital transposition techniques have been discussed in greater detail.
