Abstract
RECOMMENDATIONS
STANDARDS:
There is insufficient evidence to support treatment standards.
GUIDELINES:
There is insufficient evidence to support treatment guidelines.
OPTIONS:
Treatment options in the management of isolated fractures of the atlas are based on the specific atlas fracture type. It is recommended that isolated fractures of the atlas with an intact transverse atlantal ligament be treated with cervical immobilization alone. It is recommended that isolated fractures of the atlas with disruption of the transverse atlantal ligament be treated with either cervical immobilization alone or surgical fixation and fusion.
Abstract
An unusual fracture/dislocation of the atlas that defies classification is reported. Posterior dislocation of the left occipital condyle resulted in loss of articulation with the superior articular surface of the atlas. It could be considered a unilateral atlanto-occipital dislocation or possibly a Jefferson fracture variant. The patient suffered only a mild, temporary neurological deficit and was treated conservatively.
