Pre-operative distraction lengthening for radial longitudinal deficiency.

Patients treated for total radial aplasia have been reviewed. It was possible to re-align the carpus by radialization in five out of six limbs treated with pre-operative distraction, but in only one out of six treated without distraction. The average improvement in radial angulation in the non-distraction group was 19 degrees and in the distraction group 38 degrees. The average improvement in radial translation was 16 mm and 17 mm in the two groups respectively. Pre-operative distraction with the Kessler device permits re-alignment of the hand without skeletal resection or excessive tension on the radial neurovascular structures.
