Subjects and methods: 89 patients with thoracolumbar and lumbar spine injury have been taken X-ray spine and computer tomography scanner spine. The cases of neurogical injuries will be taken clinical examination and injuries ligament will be operated. Results: The rate of fracture based on Denis’s classification included compression fracture: ; burst fracture ; distraction fracture 0%; dislocation fracture . Neurological deficit was listed such as compression fractures ; burst fracture ; dislocation fracture 60%. Ligament injuries consisted of compression fracture ; burst fracture ; dislocation fracture 100%. Narrow spinal canal comprised compression fracture and 0%; burst fracture and ; dislocation fracture 40% and 60%). Position of narrow spinal canal: 1/2 upper ; 1/2 lower ; wholes . Conclusion: The fracture at L1 and burst fracture are the most common. The ratio of narrow spinal canal and neurological deficit are high in burst fracture and dislocation fracture types. The position of narrow spinal canal at 1/2 upper accounted for high percentage. * Keywords: Vertebral injury; Thoracolumbar lumbar spinal injuries; Neurogical injuries. INTRODUCTION Thoracolumbar and lumbar spine injuries are the most common types of trauma to the spine, accounting for 90%. According to Mark S. Greenberg, the incidence of thoracolumbar junction spinal injuries was 64% [1]. Diagnosis and treatment depends on many factors such as types of fracture, surgical instruments and surgical qualifications. Therefore, studying and mastering the
