Improvement After Surgery in a Patient With Prolonged Tetraplegia Due to Cervical Spinal Cord Injury Without Bone Injury.

Treatment strategies for patients with cervical spinal cord injury (CSCI) without major bone injury in the acute phase are under debate. For CSCI without major bone injury, conservative treatment is often the first choice owing to the absence of fractures and spinal column instability. However, treatment of CSCI without major bone injury by either surgery or conservative measures remains controversial. We described a case of a 48-year-old man with cervical American Spinal Cord Injury Association Impairment Scale (AIS) grade C tetraplegia as a result of a fall. Computed tomography scan and magnetic resonance imaging revealed no fractures and widespread T2-hyperintense signal changes in the cord centered on C3-4. The paralyzed condition of his lower extremities remained unchanged with conservative treatment for eight months after the injury. Therefore, he underwent decompression surgery eight months after the injury. At two weeks postoperatively, he could transfer and walk using a walker. After discharge, he underwent regular home-visit rehabilitation and gradually improved his physical functions, including gait ability one year postoperatively. We encountered a case in which surgery and intensive rehabilitation eight months after the injury improved motor function. The combination of surgery in the chronic phase and postoperative rehabilitation can therefore improve the outcomes. The message in this paper is by no means a recommendation for "late surgery." However, we suggested that surgical treatment might be an option if the functional improvement is poor, as even quite late surgery can provide functional improvement.
