Assessing surgical trauma in robot-assisted pelvic fracture fixation: the role of the systemic immune-inflammatory index

The findings suggest that the postoperative SII may serve as a valuable biomarker reflecting the degree of surgical invasiveness associated with robot-assisted or conventional INFIX procedures for anterior pelvic ring fractures. A postoperative SII value exceeding 745.15 demonstrates promising predictive utility for elevated surgical trauma, with a specificity of 83.3% and sensitivity of 75%.
