A series of 14 lengthenings for congenital and posttraumatic digital deficiency has been carried out in a single stage utilizing individual, half-frame design, digital lengthening devices. These devices have afforded individual digital stability without need for additional external support and have provided between 2.0 cm and 3.5 cm lengthening per digit. In only one case was additional bone grafting necessary and in all cases the projected goal of lengthening was achieved. A slow rate of lengthening (0.25 mm in four daily increments) was associated with a minimal amount of pain, patients were able to utilize their hand for function during the lengthening period, and, in cases where physeal plates have remained open, continued growth has been experienced in the follow-up period.
