Summary

This study aims to evaluate the clinical efficacy and safety of an intelligent fracture reduction robot system in treating extra-articular distal tibial fractures. Traditional manual bone setting depends heavily on a surgeon's experience, which can sometimes lead to inconsistent alignment and increased radiation exposure. This clinical trial compares robot-assisted closed reduction against the traditional surgeon-led method. The primary goal is to determine if the robotic system improves the rate of accurate fracture alignment (excellent and good reduction rate) and helps patients recover better.

Conditions

  • Distal Tibial Fracture
  • Tibial Fractures

Interventions

DEVICE

Robot-assisted closed reduction

The patient undergoes automated or human-robot collaborative closed fracture reduction powered by an intelligent robotic system. The system integrates deep-learning-based bone segmentation, automatic reduction planning, and a self-adaptive 2D-3D image registration framework to achieve sub-millimeter positioning feedback and force-position collaborative security gates. Following successful reduction, the fracture is fixed with a distal tibial locking plate via the minimally invasive percutaneous plate osteosynthesis (MIPO) technique.

PROCEDURE

Traditional surgeon-led reduction

The patient undergoes conventional closed or open fracture reduction performed entirely by the surgical team based on traditional clinical experience under ordinary C-arm fluoroscopic guidance. Internal fixation is achieved using standard distal tibial locking plates or intramedullary nails according to the surgeon's choice and standard of care.
