The Results of External Fixation of the Radius in the Treatment of Comminuted Intraarticular Fractures of the Distal End

Abstract

14 unstable comminuted intraarticular fractures of the distal radius were treated by the use of the A/O mini-external fixator. The distal pins were inserted in the distal fragment, thus leaving the wrist joint free to mobilize. Clinical results were assessed at 3 to 12 months using the Sarmiento demerit point system. Nine were male and five female, with a mean age of 37 years. Ten fractures were closed and four were open. 11 patients (78.5%) had an excellent functional score and three (21.5%) had a good score. All patients had normal wrist morphology with an average radial length of 11 mm, radial angle of 23° and a mean volar angle of 12°. 12 patients had anatomical radio-carpal and radio-ulnar joints and two patients had a step less than 2 mm at the radio-carpal surface. This method has proved in our experience to be reliable in maintaining the position as well as allowing early functional recovery.
