| 摘 要： | 用在１５８２例颈椎侧位片中发现的７６例环椎后桥进行了Ｘ线观察。环椎后桥由环枕韧带钙化、骨化形成。后格在可为单侧或双侧,并把环椎后桥分为完全型和不完全型,后者又分为前突型、后型、双突型、中央型。７６例中,临床症状与后桥孔大小无明显关系。并指出,不完全型环椎后桥在Ｘ光片上须与骨折折及软组织异物相鉴别。

| Abstract: | 76 retro-atlas bridges detected from 1582 cases of lateral cervical spine radiographs were ob-served radiologically. Retro-atlas bridges were formed by the calcification and ossification of the atlantooccipital ligament. They were unibilateral or bilateral, and divided into two types: the complete and incomplete type. The incomplete retro-atlas bridges could be subdivided into "forward process", "backward process", "double process" and "central process". No definite links were found between clinical symptoms (such as numbness in the upper extremity, dizznes) and the size of the retro-atlas bridges. The incomplete retro-atlas bridges differentiated from atlas fracture and foreign body of the soft tissue. |
