At lumbar spine level traumatic dislocation lesion realizes“traumatic spondylolisthesis or traumatic bilateral lumbar facet locked syndrome”. The aim of the present paper is to report this rare lesion and discuss its mechanism and management. A case report is followed by Literature review made on Medline and scholar google database from 2000 to 2015. The case report concerned a 33-year-old man, who refused to wear a seat belt, injured his lumbar spine following a motor vehicle accident. L4-L5 spondylolisthesis occurred after the vehicle rolled over several times. Sixteen months after the accident the patient had a favorable outcome. Literature review on Medline and scholar google database from 2000 to 2015 was carried out and five cases of traumatic spondylolisthesis were found. The Sex ratio was 3/2. Surgical treatment consisted of posterolateral interbody fusion. Traumatic lumbar spine spondylolisthesis is rare. When it occurs, it is always associated with vertebral lumbar fracture. L4-L5 traumatic spondylolisthesis was caused by a high-energy mechanism and improper use of seat belt.展开更多
