【Abstract】 ObjectiveTo explore the application value of sacroiliac screws combined with anterior column screws in the treatment of anteriorposterior pelvic ring injury. MethodsThirtyeight patients with anteriorposterior pelvic ring injury were randomly divided into two groups by drawing lots, with 19 cases in each group.The observation group received fixation using sacroiliac screws combined with anterior column screw, and the control group was treated with sacroiliac screws combined with external fixator.The intraoperative blood loss, operative duration, postoperative pain, time of postoperative first ambulation and Matts pelvic reduction were compared between the two groups. The postoperative complications were recorded. ResultsCompared to the control group, the intraoperative blood loss and the time of postoperative first ambulation were less or shorter, the operative duration was longer in the observation group(P＜0.05). The excellent rate of pelvic reduction was higher and the incident rate of complication was lower in the observation group compared to the control group, but there were no significant differences between the two groups(P＞0.05).The pain scores of the observation group were significantly lower than those of the control group after 2 day and 1 week of operation(P＜0.05). ConclusionFor the treatment of anteriorposterior pelvic ring injury, sacroiliac screws combined with anterior column screws can obtain a definite efficacy, can shorten the recovery process, reduce postoperative complications and is highly valuable for clinical application.
