ABSTRACT

Objective To explore the clinic results of the locking compression plate fixation for injuries at the posterior ring of pelvis. Methods 5 patients with injuries at the posterior ring of pelvis were treated with locking compression plate fixation. 2 of them resulted from crashing, 2 from crushing and 1 from falling. They included 4 males and 1 female and their average age was 35.6 years. According to AO classification system, there were 1 type B1, 2 type B2, 1 type B3 and 1 type C1; according to Dennis classification system, there were 4 section I fractures and 1 section II fracture. Results All the patients were available at follow-up, with a mean period of 5.8 months (ranging from 3 to 12 months). The average intraoperative time was 50 minutes (ranging from 30 to 80 minutes), and no patient underwent blood transfusion because the intraoperative blood loss was only 100 to 400 mL. There was no iatrogenic nerve injury and all the incisions healed during the primary procedure. The function and sense of sacroiliac joint and low extremities recovered to normal. Conclusion The locking compression plate fixation is one of the effective methods for treatment of injuries at the posterior ring of pelvis, for it is simple and minimally traumatic, and has a low rate of complications.
