Summary
Mixed reality surgical navigation (MRSN) with an unlocking closed reduction technique (UCRT) frame improved pelvic fracture reduction accuracy. This innovative approach enhanced patient outcomes by reducing complications and radiation exposure.
Area of Science:
- Orthopedic Surgery
- Medical Technology
- Trauma Management
Background:
- Pelvic ring disruption (PRD) presents significant mortality and disability risks.
- Inadequate fracture reduction can lead to severe complications like pelvic deformity and delayed healing.
Purpose of the Study:
- To introduce and evaluate a novel mixed reality surgical navigation (MRSN) system combined with an unlocking closed reduction technique (UCRT) frame.
- To assess the efficacy of MRSN-UCRT in improving pelvic fracture reduction and fixation.
Main Methods:
- Thirty patients with PRD underwent CT scans for 3D model segmentation.
- MRSN guided the insertion of auxiliary screws for pelvic bone grasping and planned reduction trajectories.
- Closed reduction was performed, followed by fixation with CS screws.
Main Results:
- Excellent reduction quality (Matta score ≤4 mm) was achieved in 29 out of 30 cases.
- All fractures healed without complications, with good functional recovery (average Majeed score 91.0).
- The technique improved reduction accuracy and reduced radiation exposure without significantly increasing operation time.
Conclusions:
- MRSN with UCRT frame is an effective technology for pelvic fracture reduction.
- This method enhances surgical precision, minimizes complications, and optimizes patient recovery.
- The study demonstrates a significant advancement in managing complex pelvic ring disruptions.
