Comparing the Efficacy and Safety of Robot Assisted Minimally Invasive Treatment Versus Conservative Treatment in Elderly Patients With FFP1-2 Fragility Fractures of the Pelvis

This study is a prospective, single center, stratified randomized controlled trial designed 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.

A total of 152 patients will be enrolled and randomly assigned in a 1:1 ratio to either the robot assisted minimally invasive treatment group or the conservative treatment group. Randomization will be stratified according to FFP classification (FFP1 or FFP2) using a computer generated randomization sequence.

Eligible participants include patients aged 60 years or older diagnosed with osteoporosis related FFP1 or FFP2 pelvic fragility fractures caused by low energy trauma. The primary objective is to compare pain control, early weight bearing, functional recovery, fracture progression, venous thromboembolism events, and healthcare resource utilization between treatment strategies.

Patients in the robot assisted treatment group will undergo robot assisted minimally invasive pelvic fixation, while patients in the conservative treatment group will receive standardized nonoperative management including pain control, anticoagulation prophylaxis, rehabilitation, and osteoporosis treatment.

Outcome measures include pain scores, Majeed pelvic function score, EQ 5D, SMFA, imaging evaluation of fracture progression and healing, venous thromboembolism events, laboratory parameters, muscle mass changes, bone mineral density, opioid consumption, complications, and healthcare costs. Follow up assessments will be performed at postoperative day 3, 2 weeks, 1 month, 2 months, 3 months, 6 months, and 1 year.
