Functional and radiological outcomes following sacroiliac screw fixation of posterior pelvic ring injuries: A retrospective study.

Background and Aims: Posterior pelvic ring disruption has been associated with high-energy trauma, and significant morbidity and mortality. We aimed to determine functional and radiological outcomes following sacroiliac screw fixation of posterior pelvic ring injuries at a major trauma centre. Methods: Patients who underwent sacroiliac screw fixation at our institution, between 1 Results: 115 patients were identified. The mean age at injury was 51.6 years (17-84 years). Most injuries resulted from falls and road traffic collisions (83.5 %). Eighty patients (69.6 %) sustained additional non-pelvic injuries and twenty-nine (25.2 %) underwent a non-pelvic procedure, most commonly limb or clavicle fracture fixation ( Conclusions: Most patients with pelvic ring injuries experienced high-energy trauma, often resulting in multiple injuries and operative interventions. Nevertheless, mortality rates were low, and most patients experienced either mild or no functional difficulties. The magnitude of the pelvic deformity pre-operatively correlates with post-operative clinical scores.
