Although rare, traumatic lumbosacral (L/S) Grade I spondylolisthesis (i.e., Lumbar locked facet syndrome) is characterized by unilateral or bilateral facet dislocations.
A 25-year-old male presented following a high velocity road traffic accident with back pain and tenderness at the L/S junction. His radiologic images showed bilateral locked facets at the L5/S1 level with Grade 1 spondylolisthesis, bilateral pars fractures, acute traumatic L5/S1 disc herniation, and disruption of the anterior and posterior longitudinal ligaments. After undergoing a L4-S1 laminectomy with pedicle screw fixation, he became asymptomatic and remained neurologically stable.
L5/S1 facet dislocation whether unilateral or bilateral needs to be diagnosed early and treated with realignment and instrumented stabilization.
创伤性腰骶部I度椎体滑脱（即腰椎小关节交锁综合征）虽然罕见，但特征为单侧或双侧小关节脱位。
一名25岁男性在高速道路交通事故后出现腰骶部交界区疼痛和压痛。其影像学图像显示L5/S1水平双侧小关节交锁伴I度椎体滑脱、双侧椎弓根骨折、急性创伤性L5/S1椎间盘突出以及前后纵韧带断裂。在接受L4-S1椎板切除术并进行椎弓根螺钉固定后，他症状消失且神经功能保持稳定。
L5/S1小关节脱位无论单侧或双侧均需早期诊断，并通过复位和器械稳定治疗。
