Distal radius and ulna fractures are the most common fractures seen in England, occurring at a rate of 22/10,000 person years. Kirschner (K)-wire fixation is a well-accepted method of treating these fractures. There is a surprising paucity of evidence on the subject of prophylactic antibiotics and the duration of K wires can be left in, as these relate to infection rates. We therefore present the results of our protocol for distal radius K-wire fixation for which: no antibiotic prophylaxis was given; we used a percutaneous (not buried) technique, where the K wires were removed after 4 weeks, and the patient has a total of 6 weeks in cast (last 2 wk without wires). The results of the last 100 consecutive patients who were treated with manipulation and K wiring of dorsally displaced distal radial fractures in a standard district general hospital over a 2-year period were analyzed retrospectively. A total of 100 patients had 176 K wires inserted. The mean age was 32.5 years. The mean time to pin removal was 29.4 days. The infection rate was 2%. These results illustrate a safe and clinically effective protocol for K-wire fixation in treating distal radius fractures. On the basis of this study, we do not advocate the use of prophylactic antibiotics, postulating that they do not affect infection rate and thereby eliminating potential antibiotic adverse effects. Furthermore, we do not bury the K wires, which allows for their removal in clinic, thus preventing risks of further operative procedures.
