Report of two cases.) | Neurenteric cysts are rare benign lesions of the central nervous system that are lined by endodermal cell-derived epithelium. Although they occur mostly in the spine, they can occur intracranially, most often in the posterior fossa.

Schmidt, Meic H. | Frameless stereotactic image-guided C1-C2 transarticular screw fixation for atlantoaxial instability: review of 20 patients | Atlantoaxial instability can result from trauma, rheumatoid arthritis, congenital malformation, or tumor invasion. The goal of treatment is stabilization of the C1-C2 complex to prevent neurologic and neurovascular compromise. First described in 1987 by Magerl and Seemann, C1-C2 transarticular screw... | Transarticular screws; Atlantoaxial instability; Frameless stereotaxy; Cervical spine; Surgical navigation; Trajectory planning | 2005 |

Dailey, Andrew T. | Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 10: Lumbar fusion for stenosis without spondylolisthesis | Lumbar stenosis is one of the more common radiographic manifestations of the aging process, leading to narrowing of the spinal canal and foramen.
