Update on external fixators in the treatment of wrist fractures.

Fifty fractures of the distal radius in 49 patients were treated by either a Roger Anderson device or a Hoffman C-series external fixator. The radiographic and clinical results were evaluated for comparison of the use of the two fixators. The follow-up period for the entire group averaged 15.9 months. For 12 patients personally examined and 12 returning a questionnaire, the follow-up period averaged 27.7 months. The Hoffman fixator and Roger Anderson device gave predictably good results in the treatment of comminuted intra-articular fractures of the distal radius when used in the active age group. Neither was found to yield superior functional results over the other, although the Hoffman fixator had a more rigid configuration. Serious complications may result from the use of external fixators, but these can be minimized by proper technique and care.
