The presented video explains the technique of posterior fixation of the atlantoaxial joints in patients with atlantoaxial instability. Prof. Atul Goel has pioneered the method and is the gold standard used to fix the craniovertebral junction. The technique consists of opening the C1 C2 joint, denuding the joint’s articular cartilage, putting bone chips into the joint, and performing a plate and screw fixation of the region. The C1 screw is through the lateral mass of C1, and the C2 screw engages the C2 pedicle. It demonstrates the nuances to perform a solid atlantoaxial fixation. The targeted audience includes neurosurgeons and spine surgeons. The viewer will learn the tricks for performing an ideal C1-C2 fixation.

This video demonstrate Goel’s Technique of C1-C2 Fixation. Basically, it’s posterior fixation of the atlantoaxial joint. As we all know, the atlantoaxial joint is the most mobile joint of the entire spine. And it is potentially the most liable to become unstable. Hence, learning the technique of fixing the atlantoaxial joint forms an important armamentarium for a neurosurgeon.
The treatment of patients with atlantoaxial dislocation is a surgical challenge. And once you achieve a successful outcome for these patients, this surgical outcome is extremely gratifying. However, at the same time, the complications of surgery can be potentially lethal. Whilst a successful surgery has a great potential to give a new life to the patient and to their families, any complication can be devastating. Hence, it is absolutely mandatory to understand the anatomy of the craniovertebral junction before embarking upon its surgery.
Now, what are the key points while performing a posterior atlantoaxial fixation? The key points involve opening of the atlantoaxial joint, denuding of the articular cartilage, stuffing of bone graft chips into the joint cavity, and direct insertion of screws into the facets of atlas and axis. These steps form the basis of Goel and Laheri technique of atlantoaxial stabilization.
The position of the patient while performing this surgery is a head high position under cervical traction. This position provides a stabilization of the head in an optimum surgical position. It actually keeps the head floating and avoids pressure over the face and eyeballs during surgery.
The next important step is a sectioning of the C2 ganglion. This sectioning is 100% safe and can be done whenever the exposure of the atlantoaxial facetal articulation is less than complete.
When done properly, a sectioning of the C2 ganglion provides a window to the atlantoaxial joint. The next important step is obtaining of the bone graft. We always use an autograft that is derived from the iliac crest.
After the procedure is performed, all the muscles attached to the C2 spinous process are sectioned to avoid movements in the region. This is another key step while performing the C1-C2 fixation.
Direct handling of the facets and their manual manipulation enhances the scope of use of atlantoaxial fixation for cases with atlantoaxial instability, basilar invagination, irreducible atlantoaxial dislocation, rotatory atlantoaxial dislocation, and for cases with extensive trauma to the region that results in displacement of facets.
Now let’s go ahead and see the surgical technique of Goel’s technique of C1-C2 fixation.
