BACKGROUND: The aim of this study was to explore the efficacy of temporary balloon occlusion of the abdominal aorta assisting open reduction and internal fixation (ORIF) in the treatment of complex acetabular fracture.

MATERIAL AND METHODS: From August 2000 to October 2011, a total of 48 patients with complex acetabular fracture were enrolled in this study. Average operative time, intraoperative blood loss volume, blood transfusion volume, satisfactory reduction, and postoperative functional recovery rate were recorded and compared between the 2 groups.

RESULTS: A significant difference was observed between the 2 groups in operative time (P=0.003). For intraoperative blood loss and blood transfusion, ORIF combined with temporary balloon occlusion of abdominal aorta techniques appeared to be superior to normal ORIF (blood loss: P=0.007; and blood transfusion: P=0.019, respectively). However, no differences were observed in postoperative blood loss or transfusion (P>0.05). Patients in group A showed better hip function than those in group B (group A: a good-to-excellent rate of 77.8%; group B: a good-to-excellent rate of 78.3%; P>0.05). With regard to the incidence of postoperative complications, there were no significant differences between the 2 groups (group A: 9/18; group B: 11/23; P=0.890).

CONCLUSIONS: In the treatment of complex acetabular fracture, temporary balloon occlusion of the abdominal aorta is a reliable technique to assist ORIF surgery to staunch the flow of blood.
