RESUMEN
<p><b>OBJECTIVE</b>To introduce a method of three-column classifications for Pilon fractures and observe clinical utility on column fixation.</p><p><b>METHODS</b>From June 2007 to March 2010,a total of 27 patients (29 ankles, 26 males and 1 female,ranging in age from 23 to 59 years, with an average of 33.1 years) with Pilon fractures were treated through column fixation by using semitubular plates or screws with anteromedial, anterior, posterolateral,posteromedial approach. And postoperative follow up were carried out.</p><p><b>RESULTS</b>The mean follow up was 17.5 months(ranged,5 to 33 months). According to the Mazur ankle grading system, the outcome was excellent in 20, good in 4 and fair in 5 ankles. Patients in this group did not have complications of wound dehiscence, deep infection, osteomyelitis, nonunion, ankylosis, and joint instability.</p><p><b>CONCLUSION</b>Based on the three-column classification, the clinical results for the treatment of Pilon fractures demonstrate the rationality and efficiency of this method.</p>
