Traumatic L5-S1 spondylolisthesis.

We report a case of traumatic spondylolisthesis in a 31-year-old man struck by a steel I-beam. Although most reported traumatic spondylolisthesis cases are from low-energy trauma, this was a high-energy trauma case. The initial examination revealed no signs of cauda equina syndrome, and the patient's spinal injury was primarily capsuloligamentous. We present this rare case, with a review of pertinent literature and treatment mechanisms for traumatic spondylolisthesis.
