Preliminary soft tissue distraction in congenital forearm deficiency.
Four patients (five limbs) were treated with preliminary soft tissue distraction using an Orthofix external distractor. The patient's ages ranged from 6 months to 14 years. Forearm deficiencies treated included partial absence of the radius (one patient), radial aplasia (two patients, three limbs), and partial absence of the ulna (one patient). Soft tissue distraction (mean, 55 days) was continued in radial deficiency until the hand could be passively centralized without residual radial deviation, allowing centralization to be accomplished through a single mid-dorsal incision. Mean measurement of distraction for the radial deficiencies was 1 cm. In the ulnar deficiency, soft tissue distraction was carried out until the cut radius was distal to the partially absent ulna (98 days) allowing for the creation of a one-bone forearm using the entire radius. Distraction (1 mm/day) was done by the children's parents with no distractor removed because of patient intolerance. All radial deficiency limbs remained centralized at a mean followup period of 14 months.
