Posterior sacroiliac osteotomy: an alternative to the ilioinguinal approach for pelvic reconstruction in misalignment lesions

Abstract

Pelvic ring fractures occur in association with potentially fatal lesions, whose treatment is a priority in the polytrauma setting. As consequence, the definitive orthopedic approach may be postponed, leading patients to chronic and potentially disabling deformities. The treatment of these deformities is a challenge, requiring highly complex and staged surgical reconstructions. The ilioinguinal approach has been widely used in these surgeries, because it allows the release and mobilization of the hemipelvis and, in some cases, anterior fixation of the sacroiliac joint. However, in most cases, stable pelvic ring reconstruction requires this approach to be complemented by two other surgical approaches (posterior longitudinal and Pfannestiel). This requirement critically increases the surgical time and the risk of complications, such as neurovascular lesions and surgical wound infection. The current study presents a posterior osteotomy technique for posterior and anterior release of the sacroiliac joint, eliminating the need for ilioinguinal approach. The technique is performed by posterior longitudinal access; it allows adequate mobilization of the hemipelvis and reduction of vertical and rotational deformities, before the spinopelvic fixation and reduction of the pubic symphysis.

Comparison of clinical effects of two surgical approaches in the treatment of acetabular fractures

“…It has been reported that there was a significant difference in incision length between the lateral rectus abdominis approach and the modified Stoppa approach. [16][17][18] Meanwhile, the operation time and intraoperative blood loss of patients with surgery through the lateral rectus abdominis approach were significantly less than those with modified Stoppa approach. 19 In our study, the observation group showed shorter incision length and less amount of intraoperative blood loss than those of the control group, with statistically significant differences (p<0.05).…”
