Summary
Posterior cervical fixation using lateral mass screws is safe and effective without intraoperative fluoroscopy. This approach reduces radiation exposure and operating time for spinal fusion procedures.
Area of Science:
- Orthopedics
- Neurosurgery
- Spinal Surgery
Background:
- Lateral mass screws are widely used for posterior cervical fixation, offering immediate stability.
- This method provides biomechanical stability comparable or superior to other fixation techniques.
Purpose of the Study:
- To evaluate the safety and efficacy of positioning lateral mass screws without intraoperative fluoroscopy.
- To determine if fluoroscopy is essential for accurate screw placement in posterior cervical fixation.
Main Methods:
- A prospective study was conducted to assess screw placement without intraoperative fluoroscopy.
- Operators relied on a detailed understanding of lateral mass anatomy and established positioning guidelines.
Main Results:
- Lateral mass screws can be safely and effectively positioned without intraoperative fluoroscopy.
- The absence of fluoroscopy did not compromise the safety or effectiveness of the procedure.
Conclusions:
- Posterior cervical fixation with lateral mass screws is feasible and safe without intraoperative fluoroscopy.
- This technique reduces radiation exposure and operative time, enhancing patient safety and surgical efficiency.
