Abstract
The Pennig model external fixator is a new device, which allows early excercise of the wrist joint without displacement of the fragments, by dynamic axial external fixation. We used this device for treating 6 patients. Internal fixation was supplemented in one patient, and bone grafting in one. The range of motion in the wrist joints with the external fixator was 20 to 58 degrees (mean 28 degrees). Functional results after a follow-up of 5 to 13 months (mean 7 months) were excellent in 2 patients, good in 2 patients and fair in one. Anatomical restoration was obtained in all patients radiographically. One case was complicated by Guyon canal syndrome and RSD, and displacement occurred in one patient following loosening of the screw.
