A study was organized to evaluate the use of a one-plane external fixation device to treat comminuted fractures of the distal radius. Clinical and roentgenographic data were obtained in 20 patients with a followup ranging from 12 to 20 months. The results were graded 14 excellent, 4 good, 2 fair, and none poor. The use of the Clyburn External Fixation Device with supplemental radial styloid Kirschner wire fixation achieved acceptable results in the treatment of comminuted distal radius fractures and proved to be easily applied.
