Summary
This study presents a modified translaminar screw technique for cervicothoracic junction fixation. The technique enhances safety and reduces operative time, proving effective in clinical application.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Orthopedic Surgery
Background:
- Cervicothoracic junction (C7-T2) stabilization is critical.
- Traditional translaminar screw techniques carry risks of spinal canal violation.
Purpose of the Study:
- To describe and illustrate a modified translaminar screw technique for cervicothoracic junction (C7-T2) fixation.
- To evaluate the safety and efficacy of this modified technique.
Main Methods:
- A modified technique involving a unicortical 'hole' in the contralateral lamina was used in 12 patients.
- Direct visualization of screw insertion through the unicortical hole prevents spinal canal violation.
Main Results:
- The modified technique was applied to 12 patients (8 males, 4 females; average age 52 years).
- Mean operative time was 205 minutes, with a mean blood loss of 445 ml.
- Average follow-up was 17 months, demonstrating safety and effectiveness.
Conclusions:
- The modified translaminar screw technique is safe and effective for cervicothoracic junction fixation.
- Direct visualization via a unicortical hole reduces spinal canal violation risk and shortens operation time.
