Bilateral facet dislocation on L4-L5 without neurologic deficit.
We present a case of traumatic bilateral facet dislocation of L4-L5 without neurologic deficit in a 47-year-old woman after a motor vehicle accident. We considered that the mechanism of injury was the composition of hyperflexion, distraction, and rotation. Open reduction was easily performed when the obstacles consisting of the disrupted joint capsule and synovial membrane were completely removed. Also, posterior interbody and posterolateral fusion and pedicle screw augmentation are recommended because of surgeon familiarity, the absence of additional injury for unstable injury, and the safety of this treatment.
