Résumé
<p><b>OBJECTIVE</b>To explore the best opportunity of structure reconstruction for complex acetabular fracture in order to provide the accurate time for clinical operative treatment.</p><p><b>METHODS</b>Complex acetabular fracture patients were divided into experimental group (93 cases, 96 hips) and control group (98 cases, 101 hips) randomly according to the operative time. The operation of patients were done respectively at the 7th, 10th day after injury in experimental group and control group. The operative time, the excellent and good rate of reduction,the postoperative complications,the joint function (ache to walk,joint activity),the SF-36 were evaluated.</p><p><b>RESULTS</b>(1) The operative time of experimental group was obviously shorter than control group according to different fracture classification. (2) According to the standard of Matta' joint function and X-ray, the experimental group was better than control group. (3) The excellent and good rate of reduction in experimental group was obviously higher than control group, according to CT scan before operation and after operation.</p><p><b>CONCLUSION</b>The early structure reconstruction of complex acetabular fracture can obviously decrease operative time and complications, increase the rate of operative reduction.</p>
