Chiari malformation type I and basilar invagination originating from atlantoaxial instability: a literature review and critical analysis.

Arthur Wagner, Lukas Grassner, Nikolaus Kögl, Sebastian Hartmann, Claudius Thomé, Maria Wostrack, Bernhard Meyer,

INTRODUCTION:Recently, a novel hypothesis has been proposed concerning the origin of craniovertebral junction (CVJ) abnormalities. Commonly found in patients with these entities, atlantoaxial instability has been suspected to cause both Chiari malformation type I and basilar invagination, which renders the tried and tested surgical decompression strategy ineffective. In turn, C1-2 ... Read more >>

Relationship between the atlantodental interval and T1 slope after atlantoaxial fusion in patients with rheumatoid arthritis

Byeong Jin Ha, Yu Deok Won, Jeil Ryu, Myung-Hoon Han, Jin Hwan Cheong, Jae Min Kim, Hyoung-Joon Chun, Koang-Hum Bak, In-Suk Bae,

Abstract 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 cervical kyphosis are observed. We investigated various factors under the hypothesis that the atlantodental interval (ADI) ... Read more >>
