This prospective randomized controlled trial aims to compare the efficacy and safety of robot assisted minimally invasive treatment versus conservative treatment in elderly patients with FFP1-2 fragility fractures of the pelvis. Eligible patients will be stratified according to FFP classification and randomly assigned in a 1:1 ratio to receive either robot assisted minimally invasive fixation or standardized conservative treatment. Primary and secondary outcomes include pain relief, functional recovery, fracture progression, venous thromboembolism events, complications, and healthcare resource utilization. The study aims to provide evidence for optimizing treatment strategies in elderly patients with pelvic fragility fractures.
