Superior gluteal artery injury risk from third sacral segment transsacral screw insertion

Safety and Preliminary Effectiveness of Lateral Transiliac Sacroiliac Joint Fusion by Interventional Pain Physicians: A Retrospective Analysis

“…24 However, other authors question the relationship of dysmorphic anatomy to increased vascular risk. 23 Few clinical studies have reported "real world" data on the incidence of lateral vascular injury secondary to SI joint fixation and those reported rates are low 0.6-1.2%. 13,25 Proper surgical technique and soft tissue protective tools and sleeves for the surgical instruments utilized during the procedure have been espoused as critical for safely performing iliosacral fixation since adoption of this procedure.…”

“…Consistent with the cadaveric studies, a significant number of patients had either superior deep branch or superficial branch vessels in the implant target zones at the levels of S1, 21 S2, 22 and S3. 23 Injuries to these branches would typically result in modest hemorrhage during the procedure, but would rarely be life threatening. Rather, these injuries may present as a perioperative hematoma, which have been described in rigorously controlled prospective clinical studies.…”
