Abstract
RATIONALE: Traumatic nucleus pulposus sequestration (TNPS) usually occurs concurrently with severe destruction of bone. TNPS combined with a slight thoracolumbar flexion- distraction fracture, triggering a disastrous nerve injury, has rarely been reported. Due to the atypical radiologic manifestations, such a patient can easily be overlooked. PATIENT CONCERNS: Hereby, we present a TNPS patient as well as a slight thoracolumbar flexion-distraction fracture and serious neurologic symptoms. DIAGNOSES: T12 spinous process fracture, L1 flexion distraction fracture, thoracolumbar traumatic nucleus pulposuse sequestration and lower limbs incomplete paralysis INTERVENTIONS:: To avoid further neurologic compromise, an urgent laminectomy and exploration of the spinal canal was performed. OUTCOMES: After decompression OR and 4 months rehabilitation, the patient's neurologic function improved remarkably. LESSONS: A slight flexion-distraction fracture following injury is liable to eclipse the concurrence of TPNS. For this patient, a high-resolution MRI was needed to make a definitive diagnosis and guide surgery. Once TPNS has been diagnosed, sufficient decompression and discectomy surgery should be performed without delay.
