Summary
This guide details posterior C1 lateral mass and C2 pars/pedicle screw fixation for atlantoaxial joint instability. It offers a step-by-step surgical approach with anatomical and radiographic insights for surgeons.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
Background:
- Atlantoaxial surgical fixation is a common treatment for atlantoaxial joint instability.
- The posterior approach using C1 lateral mass screws and C2 pars or pedicle screws is frequently employed in adults and children.
Purpose of the Study:
- To provide a detailed, step-by-step technical guide for posterior atlantoaxial fixation.
- To illustrate the procedure using cadaveric dissections and fluoroscopic images.
Main Methods:
- Utilized an embalmed human cadaveric specimen for dissection and technique demonstration.
- Incorporated intraoperative fluoroscopic images from a patient undergoing C1/C2 fixation.
- Documented each step with photographs, highlighting critical aspects and anatomical-radiographic correlations.
Main Results:
- Presented photographic and radiographic illustrations of pertinent anatomy and surgical technique.
- Detailed the nuances of each procedural step.
- Included strategies for avoiding common complications.
Conclusions:
- The provided step-by-step guide is a valuable resource for surgeons and trainees performing posterior C1/C2 fixation.
- This technical note addresses the widespread use of this surgical technique.
