Acute Traumatic L5-S1 Spondylolisthesis: A Case Report

Acute traumatic spondylolisthesis of the lumbar spines is a rare condition. Its incidence and prevalence, thus, cannot be exactly estimated. This study was a report of this condition. A male patient was injured from falling object. Pain, deformity at lumbosacral region and paraparesis were presented. Plain radiographic study showed 75% anterior translation of L5-S1 spondylolisthesis. Operation was performed by surgical open reduction by posterior approach of lumbosacral spine and then maintained reduction using pedicular screw instrumentation. Decompressive laminectomy and posterolateral fusion were performed for nerve root decompression. Intraoperative and early postoperative complications were not reported. Postoperative plain radiographs had remained 25% of anterior translation of L5-S1. After six months, the patient was clinically improved.
