A series of 14 lengthenings for congenital and posttraumatic digital d
eficiency has been carried out in a single stage utilizing individual,
half-frame design, digital lengthening devices. These devices have af
forded individual digital stability without need for additional extern
al 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 fo
r function during the lengthening period, and, in cases where physeal
plates have remained open, continued growth has been experienced in th
e follow-up period.
