Summary
Computer-assisted navigation (CAN) in spine surgery significantly reduces screw perforation and operative time, especially after six months of use. This technology offers substantial benefits, particularly for less experienced surgeons, improving patient safety and surgical efficiency.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Medical Technology
Background:
- Computer-assisted navigation (CAN) in spine surgery offers advantages over conventional intraoperative image intensifiers (CIII), including lower screw misplacement rates and reduced radiation exposure.
- Few studies have detailed the learning curve associated with implementing CAN in spinal procedures.
Purpose of the Study:
- To analyze the learning curve of computer-assisted navigation (CAN) in spine surgery by evaluating pedicle screw accuracy and operative time.
- To compare the performance of two surgeons with different experience levels using CAN versus CIII.
Main Methods:
- Two consecutive case cohort studies were conducted on two spine surgeons (A and B) with varying experience levels.
- Lumbar pedicle screw cortical perforation rates and operative times were analyzed and compared between CAN and CIII at initial, 6-month, and 12-month intervals.
Main Results:
- Overall, CAN spine surgery demonstrated lower cortical perforation rates and reduced operative times compared to CIII for both surgeons.
- Significant improvements in perforation rate and operative time were observed after 6 and 12 months of CAN system usage for both surgeons.
- The learning curve showed a marked decrease in errors and time after six months, plateauing by twelve months.
Conclusions:
- Computer-assisted navigation (CAN) spine surgery effectively decreases lumbar screw perforation rates and operative times in the long term.
- The learning curve for CAN is characterized by a rapid improvement within the first six months, followed by stabilization.
- CAN technology is particularly beneficial for less experienced surgeons, enhancing safety and efficiency in spine procedures.
