Minimally invasive percutaneous cannulated screw fixation for pelvic fractures: a retrospective case cohort study of clinical and radiological outcomes

Objective To describe the clinical and radiological outcomes of minimally invasive percutaneous cannulated screw fixation (MIPCSF) in a consecutive series of patients with unstable Tile B/C pelvic fractures, and to explore associations between Tile classification, surgical timing, and outcomes. Methods A single-center retrospective cohort study was conducted on 248 consecutive patients with unstable Tile B/C pelvic fractures who underwent MIPCSF.
