Summary
Background:
There is controversy as to which is the preferred treatment for distal radius intra-articular fractures – anatomic reduction or external fixation.
Objectives:
To evaluate the radiologic and functional outcome following external fixation of these fractures.
Methods:
Between January 2003 and March 2005, 43 patients with distal radius intra-articular fractures were treated using a mini-external AO device. Follow-up of 38 of the patients included X-rays at 1 week, 6 weeks and 6 months postoperatively. The Visual Analogue Scale was used to assess pain levels, and the Lidstrom criteria scale to evaluate functional outcome and wrist motion. Clinical and radiographic results were correlated.
Results: According to the Lidstrom criteria, the results were excellent in 31%, good in 61% and fair in 5.5%; 2.5% had a poor outcome. The results of the VAS were good. Thirty-five patients gained a good range of wrist movement, but 3 had a markedly reduced range. We found statistical correlation between the radiographic and clinical results, emphasizing the value of good reduction. There was no correlation between fracture type (Frykman score) and radiologic results or clinical results.
Conclusions: External fixation seems to be the preferred method of treatment for distal radius intra-articular fractures, assuming that good reduction can be achieved. The procedure is also quick, the risk of infection is small, and there is little damage to the surrounding tissues.
