Robot-Assisted Closed Reduction and Internal Fixation for Femoral Shaft Fractures

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.
