Traumatic nucleus pulposus prolapsus (TNPP) are usually carried severe spinal injuries, such as spinal fractures and dislocations[1].It usually triggered a disastrous nerve injury. However, due to the biomechanical characteristics of disc, shearing and torsion stress could also give rise to nucleus pulposus prolapsus and subtle fracture[2-3].Under these circumstances, TNPP is easily neglected and missed .Here, we experienced a case combined with a thoracolumbar slight fracture and severe neurological symptom，and our case is the absence of dislocation.
