Abstract
Introduction It is difficult to treat atlanto-axial instability in cases with high riding vertebral artery or anomalies of craniocervical junction. We report two successful cases with trans-spinal canal screwing technique because of difficulty to perform conventional fixation methods. Case presentation Case1: A 78-year-old female suffered from progressive myelopathy due to severe spinal cord compression with congenital anomaly of craniovertebral junction. Bilateral trans-spinal canal screws from axis body with spondylolisthesis to dens were inserted by retracting dural sac medially after foramen magnum decompression and cervical laminoplasty. Case2: A 20-year-old man with spinal deformity for Leys-Dietz syndrome introduced to our hospital for treatment of syringomyelia. There was no obvious neurological deficit but spinal cord compression due to right atlanto-axial rotating dislocation was observed. Screw was inserted from the vertebral body of axis to right lateral mass of atlas via spinal canal after laminectomy of atlas.
Conclusion
Trans-spinal canal screwing technique is useful to treat atlantoaxial instability with difficulty of other fixation methods.
