Bilateral Facet Joint Dislocation C5 6 Cervical Spineођ A bilateral facet dislocation is an unstable flexion distraction type of dislocation of the cervical spine, often a result of buckling force. occasionally, the bilateral facet dislocation has been named a 'doubly locked' vertebral injury giving the impression of stability. however, due to complete ligamentous disruption, this is, in fact, an. Summary. cervical facet dislocations and fractures represent a spectrum of traumatic injury with a varying degree of cervical instability and risk of spinal cord injury. diagnosis can be confirmed with radiographs or ct scan. an mri should be performed before surgery to identify an associated disk herniation.
Bilateral Facet Dislocation Radiology Reference Article Radiopaedia Org Facet dislocation refers to the anterior displacement of one vertebral body on another. without a fracture, the only way anterior displacement can occur is by dislocation of the facets. facet dislocation can occur to varying degrees: the injury usually results from forced flexion of the cervical spine. however, where there is a degree of. Fig. 25.1 sagittal computed tomography scan revealing bilateral facet fracture dislocation at the c5 6 level.(a) scan demonstrating the left facet fracture dislocation.(b) midline of the scan demonstrating greater than 50% anterior translation of c5 on c6 consistent with bilateral facet dislocation. The “reversed hamburger”, “naked facet” and “headphones” signs represent cervical facet joint dislocations on axial cross sectional imaging. illustrating these signs in an engaging manner facilitates pattern based recognition, which can benefit trainees and radiologists. moreover, pattern based recognition can be applied to machine. The cervical spine can be divided into two main regions: the craniocervical junction, from the occiput (c0) joint to the axis (c2), and the sub axial cervical spine, which includes injuries from c3 to c7 [ 3 ]. almost two thirds of cervical spine injuries occur within the sub axial cervical spine, with dislocations occurring most commonly at c5.

Bilateral facet dislocation occurs when a vertebra’s inferior facet dislocates anteriorly over the lower vertebra’s superior facet, locking in the intervertebral foramens, creating a severely unstable fracture. 2, 3 ct has a higher sensitivity for c spine injury and is the preferred imaging modality. 2 sagittal reconstructions best identify. Locked facet joint is a type of facet joint dislocation that results from jumping of the inferior articular process over the superior articular process of the vertebra below and becomes locked in the position. it can be unilateral or bilateral. the tip of the inferior articular process is seen anterior to the superior articular process of the.
