Relationship between the atlantodental interval and T1 slope after atlantoaxial fusion in patients with rheumatoid arthritis [PDF]
BMC Surgery, 2020 Background Atlantoaxial fusion has been widely used for the treatment of atlantoaxial instability (AAI). However, atlantoaxial fusion sacrifices the motion of atlantoaxial articulation, and postoperative loss of cervical lordosis and aggravation of ...

Influence of Atlantoaxial Fusion on Sagittal Alignment of the Occipitocervical and Subaxial spines in Os Odontoideum with Atlantoaxial Instability [PDF]
Asian Spine Journal, 2019 Study Design Retrospective case analysis. Purpose We hypothesized that larger the C1–C2 fusion angle, greater the severity of the sagittal malalignment of C0–C1 and C2–C7. Overview of Literature In our experience, instances of sagittal malalignment occur

Posterior C1–C2 screw-rod salvage for Chiari I malformation with atlantoaxial instability after failed foramen magnum decompression [PDF]
Journal of Craniovertebral Junction and SpineBackground: Chiari I malformation secondary to atlantoaxial instability requires reduction and stabilization. When initial foramen magnum decompression (FMD) is performed without recognition of this instability, subsequent salvage surgery is technically ...
