Summary
The Surgix computer-assisted surgery system (CASS) significantly improves hardware accuracy and reduces radiation exposure in dynamic hip screw procedures. This advanced surgical navigation enhances patient outcomes by increasing first-trial success rates and minimizing fluoroscopy time.
Area of Science:
- Orthopedic Surgery
- Medical Technology
- Image-Guided Therapy
Background:
- Introduction of Surgix, a novel computer-assisted surgery system (CASS).
- Surgix utilizes advanced image analysis for 3D measurements, implant template visualization, and guided trajectory on fluoroscopy.
- The study aimed to compare surgical outcomes and techniques with and without the Surgix CASS.
Purpose of the Study:
- To evaluate the efficacy of the Surgix CASS in dynamic hip screw (DHS) procedures.
- To compare surgical accuracy and efficiency between procedures using Surgix and conventional methods.
- To assess the impact of CASS on radiation exposure and procedural steps.
Main Methods:
- A comparative study involving 61 DHS procedures, with 41 utilizing the Surgix system.
- Key metrics included guide wire insertion trials, fluoroscopy time (X-ray pulses), tip-apex index, screw placement, and neck-shaft angle.
- Procedures were performed by experienced users of the Surgix system.
Main Results:
- Surgix use by experienced surgeons resulted in a 77.8% first-trial guide wire insertion success rate, compared to 10% in the control group (p=0.001).
- Procedures with Surgix required fewer insertion trials (1.33 vs. 3.05, p=0.001) and significantly less fluoroscopy (17.6 vs. 30.1 pulses, p=0.009).
- No significant differences were observed in tip-apex distance, quadrant screw placement, or neck-shaft angle.
Conclusions:
- The Surgix CASS significantly enhances the accuracy of hardware positioning in DHS procedures.
- The system demonstrably reduces radiation exposure time for patients and surgical teams.
- Surgix integration into surgical practice improves overall patient outcomes through enhanced precision and safety.
