A new technology using Mixed Reality Surgical Navigation with UCRT frame to assist pelvic fracture reduction and fixation

Accurate reduction is a prerequisite for optimal screw placement. However, due to the complexity of the pelvic anatomical structure, the closed reduction process cannot be directly monitored. Consequently, the success of a closed reduction procedure relies on a certain degree of luck. Several reduction tools and techniques, including the Matta, Starr, and unlocking close reduction technique (UCRT) frames, have been developed to allow surgical navigation-assisted closed reduction to be performed. More recently, a new technology using mixed reality surgical navigation (MRSN) with UCRT frame has been developed that allows real-time monitoring of fracture fragment displacement to instruct pelvic fracture reduction. This new technology can also help determine the CS trajectory for fixation of the pelvic ring after good reduction.
