Robot-Assisted Closed Reduction and Internal Fixation for Femoral Shaft Fractures
Sponsor: Beijing Jishuitan Hospital
Summary
The goal of this clinical trial is to evaluate the safety and efficacy of robot-assisted closed reduction for patients with femoral shaft fractures. The main questions it aims to answer are: Does robot-assisted closed reduction provide a statistically significant improvement in the excellent and good reduction rates compared to conventional surgeon-performed reduction? How do the two reduction methods compare in terms of surgical efficiency, fracture healing, and patient functional outcomes? Researchers will compare the robot-assisted closed reduction group to the conventional surgeon-performed reduction group to see if robot-assisted surgery improves the precision of fracture reduction, stability of alignment, and post-operative functional recovery while minimizing trauma. Participants will: Undergo standardized screening to ensure they meet the inclusion criteria for acute, unilateral, closed femoral shaft fractures (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association \[AO/OTA\] classification 32). Be randomized in a 1:1 ratio to receive either robot-assisted closed reduction or traditional surgeon-performed closed reduction, both followed by internal fixation. Complete standardized perioperative management and follow-up assessments at 1, 3, 6, and 12 months post-surgery, including functional scales such as the Lower Extremity Functional Scale (LEFS) and the EuroQol Five-Dimensional Five-Level questionnaire (EQ-5D-5L), as well as radiographic imaging to monitor bone healing and potential complications.

Interventions
Robot-Assisted Closed Reduction
Patients in this group will undergo robotic-assisted closed reduction of the femoral shaft fracture. The procedure utilizes a robotic system for intraoperative navigation and automated reduction planning based on preoperative computed tomography (CT) imaging. The robotic system assists the surgeon in achieving precise fracture alignment. Following successful reduction, routine internal fixation (intramedullary nailing) will be performed by the surgeon.
Conventional Closed Reduction
Patients in this group will undergo traditional manual closed reduction of the femoral shaft fracture. The reduction will be performed by the surgeon using standardized traction and manipulation techniques under real-time fluoroscopic guidance. Following manual reduction, routine internal fixation (intramedullary nailing) will be performed by the surgeon.
