Key Points

The study aims to delineate the complexities of the cranio-cervical junction anatomy and assess effective surgical interventions.
Analyzed the anatomical structure of the craniocervical junction, focusing on muscle, ligament, and bony components.
Described the posterior midline and transcondylar fossa surgical approaches for various conditions.
Interventions targeted complex and unstable pathologies associated with the craniocervical junction.
Demonstrated that mastering the described surgical approaches allows treatment of most CCJ-related conditions.
Clarified the presence of significant vascular structures, including the vertebral artery, influencing surgical strategies.
Emphasized the importance of understanding dynamic and static anatomy to mitigate surgical risks.

Abstract

頭蓋頚椎移行部 (CCJ) は後頭骨と環軸椎の連結部であり, 強固な支持性を必要とするが, 同時に大きく複雑な可動域を有し, 日常生活においては頻繁に動作を行う場所でもある. このため, CCJは複雑な骨性構造, 多くの筋層・靱帯構造・関節で構成される. CCJの特徴として, 不安定性を有する疾患が多く発生し, 椎骨動脈の走行も複雑である. 硬膜内には延髄, 上位頚髄, 椎骨動脈という重要構造物を多く含む. 筋肉, 靱帯, 骨, 関節が関わる動的解剖と神経血管構造が関わる静的解剖の2つに分けて理解する. 手術は, 後方からの正中アプローチとtranscondylar fossa approachを習得することで大半の疾患の治療が可能である.
