Summary
Cervical pedicle screw fixation effectively corrects cervical kyphosis, with significant improvement in alignment and solid fusion achieved in 30 patients. This spinal surgery technique offers a safe and advantageous solution for kyphosis correction.
Area of Science:
- Spinal Surgery
- Orthopedics
- Neurosurgery
Background:
- Cervical kyphosis correction presents significant challenges in spinal surgery.
- Limited detailed reports exist on using pedicle screw fixation for cervical kyphosis.
Purpose of the Study:
- To evaluate the effectiveness of cervical pedicle screw fixation for correcting cervical kyphosis.
- To analyze clinical outcomes in patients treated with this surgical technique.
Main Methods:
- Retrospective analysis of 30 patients with cervical kyphosis treated with cervical pedicle screw fixation.
- Patients were divided into two groups: flexible kyphosis (posterior procedure alone) and rigid kyphosis (combined anterior and posterior procedure).
Main Results:
- Average cervical kyphosis improved from 29.4 degrees preoperatively to 2.3 degrees postoperatively.
- Solid fusion was achieved in all patients, with only two transient nerve root complications.
- Both flexible and rigid kyphosis showed significant correction, with rigid cases benefiting from combined procedures.
Conclusions:
- Cervical pedicle screw fixation is an effective and safe method for correcting cervical kyphosis.
- Posterior procedures suffice for flexible kyphosis, while rigid kyphosis requires combined anterior and posterior approaches for optimal bony union.
- Cervical pedicle screw fixation is the most advantageous instrumentation for this condition.
