Abstract

Lumbosacral dislocations are rare disorders. We report here the case of a 66-year-old man victim of a heavy load crush with right lumbar impact point causing lumbar trauma. The examination showed a lumbar swelling corresponding to a subcutaneous hematoma. There were no signs of spinal nerves injury. Radiographic examination showed L5-S1 anterolisthesis grade II with staged breaks of the transverse processes of L2 to L5. Computed Tomography Scan confirmed these findings and also revealed a bilateral anterior and asymmetric anterior dislocation of the L5 vertebra on the sacrum without evidence of disc herniation. The patient underwent surgery within 24 hours. After L5 laminectomy, L5-S1 discectomy and segmental reduction and stabilisation by lumbo-sacro-iliac arthrodesis. After 10-month follow-up, the patient was satisfied and did not show any discomfort.
