Background: Sacroiliac joint disruption (SJD) is a common cause of pelvic ring instability. Clinically, percutaneous unilateral S1 sacroiliac screw and anterior plating are always applied to manage SJD. The objective of this study is to elaborate their respective therapeutic traits.
Materials and methods: Patients with SJD fixed with unilateral S1 sacroiliac screw or anterior plating from June 2011 to June 2015 were recruited into this study and were divided into two groups: group A (unilateral sacroiliac screw) and group B (anterior plating). Surgical time, blood loss, frequency of intraoperative fluoroscopy and complications were reviewed. Postoperative radiograph and CT were conducted to assess the reduction quality. Fracture healing was evaluated by radiograph performed at each follow-up. Majeed score was recorded at the final follow-up to assess the functional outcome.
Results: Thirty-eight patients were included in group A and thirty-two patients in group B in this study. There was no significant difference in the demographic data of the two groups. A significant difference existed in the results for average operation time (P = .022) and blood loss (P = .000) between group A and group B. The mean frequency of intraoperative fluoroscopy was 15.82 in group A and 3.94 in group B (P = .000). All the fractures healed in this study. The rates of satisfactory reduction quality and functional outcome showed no significant difference between the two groups (P > .05). The complication rate was 15.79% (6/38) in group A and 9.38% (3/32) in group B (P = .660).
Conclusion: Compared with anterior plating, percutaneous unilateral S1 sacroiliac screw usage is less invasive; however, more intraoperative X-ray exposure and permanent neurologic damage may accompany this procedure.
