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.
