Journal De Chirurgie
|December 1, 1985
Summary
A novel posterior C1-C2 screw fixation technique allows arthrodesis using a single approach. This method is suitable for patients with C1-C2 posterior arch anomalies or prior laminectomy, showing no complications in four cases.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- C1-C2 posterior screw fixation is crucial for atlantoaxial instability.
- Existing techniques may be limited by anatomical variations or prior surgeries.
Purpose of the Study:
- To describe a posterior screw fixation technique for C1-C2 vertebrae.
- To evaluate its applicability in complex cases and assess outcomes.
Main Methods:
- A posterior surgical approach for C1-C2 screw fixation and arthrodesis.
- The technique respects anatomical landmarks and uses a single incision.
- Applicable in cases with C1-C2 posterior arch anomalies or laminectomy.
Main Results:
- The described posterior fixation technique was successfully applied.
- Four patients underwent the procedure without postoperative complications.
- The method allows for C1-C2 posterior arthrodesis.
Conclusions:
- This posterior C1-C2 screw fixation technique is safe and effective.
- It offers a viable solution for patients with challenging C1-C2 anatomy.
- The single-approach method simplifies the surgical procedure.
