Robot Assisted Treatment Versus Conventional Surgery for Tile B and C Pelvic Fractures

Comparing the Efficacy and Safety of Robot Assisted Treatment Versus Conventional Surgery in Patients With Tile B and C Pelvic Fractures

This prospective randomized controlled trial aims to compare the efficacy and safety of robot assisted treatment versus conventional surgery in patients with Tile B and C pelvic fractures. Eligible patients will be stratified according to Tile fracture classification and randomly assigned in a 1:1 ratio to receive either robot assisted minimally invasive fixation or conventional surgical treatment. Primary and secondary outcomes include pain relief, early mobilization, functional recovery, imaging outcomes, perioperative complications, venous thromboembolism events, laboratory parameters, opioid consumption, and healthcare resource utilization. The study aims to provide evidence for optimizing surgical treatment strategies for unstable pelvic fractures.

This study is a prospective, single center, stratified randomized controlled trial designed to compare the efficacy and safety of robot assisted treatment versus conventional surgery in patients with Tile B and C pelvic fractures.

A total of 88 patients will be enrolled and randomly assigned in a 1:1 ratio to either the robot assisted treatment group or the conventional surgery group. Randomization will be stratified according to Tile fracture classification (Tile B or Tile C) using a computer generated randomization sequence.

Eligible participants include adult patients diagnosed with Tile B or Tile C pelvic fractures within 3 weeks after injury. The primary objective is to compare perioperative outcomes, pain control, early mobilization, functional recovery, imaging outcomes, complications, opioid consumption, and healthcare resource utilization between treatment strategies.

Patients in the robot assisted treatment group will undergo robot assisted minimally invasive fixation using robotic navigation assisted percutaneous screw placement. Patients in the conventional surgery group will undergo standard open surgical fixation according to fracture characteristics and surgeon judgment.

Outcome measures include pain scores, Majeed pelvic function score, EQ 5D, SMFA, imaging evaluation of fracture healing, laboratory parameters, venous thromboembolism events, opioid consumption, perioperative indicators, 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.

The results of this study may provide evidence regarding the optimal surgical treatment strategy for Tile B and C pelvic fractures.
