Abstract: 【Abstract】〓Objective〓To explore the efficacy of the lumbar iliac fixation combined with external fixation for the treatment of the Denis-II sacral fractures involved with anterior rings. Methods〓Eleven cases consecutively enrolled, with Tile-c type pelvic fracture (Tile-c1 8 cases, Tile-c2 2 cases and Tile-c3 1 case) concurrently accompanied with Denis-Ⅱtype sacral fracture. The posterior lumbopelvic fixation together with anterior external fixation were adopted to stabilize the fractures. Results〓All the patients had been followed up with the average period of 34 months (from 11 months to 64 months). The bone healing was observed in 4-11 months. The excellent rate was achieved 90.9% according to the Majeed score. One case of incision infection and one case of pinholes infection were occurred, and were with debridement and removing of the external fixation. Conclusion〓Stable pelvic ring could be achieved by posterior lumbopelvic fixation in combination with the anterior external fixation. This procedure is relatively simple yet a safe and effective technique in the treatment of the anterior pelvic ring fracture with sacral fracture.
