Summary
Fluoroscopy-assisted cervical transpedicular fixation is a safe and effective stabilization technique. Biplanar fluoroscopy guidance minimizes pedicle perforation risks, ensuring high fusion rates without neurovascular complications.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Cervical spine pathologies require stable fixation.
- Transpedicular fixation offers robust stabilization.
- Fluoroscopic guidance is crucial for accuracy.
Purpose of the Study:
- To assess the accuracy of fluoroscopy-assisted cervical transpedicular fixation.
- To evaluate its efficacy across various cervical pathologies.
- To determine the rate of pedicle perforation and associated morbidity.
Main Methods:
- 210 cervical transpedicular fixations were performed in 45 patients.
- Indications included trauma, degenerative disease, tumors, and Pott's disease.
- Biplanar fluoroscopy and Doppler ultrasonography were utilized for guidance and assessment.
Main Results:
- 91% of pedicle screws achieved correct positioning (Grade I).
- An acceptable position (Grade II) was noted in 8% of screws.
- A 9% pedicle perforation rate occurred with no neurovascular injury or instrumentation failure; 100% fusion rate.
Conclusions:
- Cervical transpedicular fixation provides strong spinal stabilization.
- Biplanar fluoroscopy significantly reduces pedicle perforation risk.
- This technique is safe and effective for diverse cervical conditions.
