Spinal cord injuries (SCI) seriously impair the quality of life, functional status, and social independence of the patients. Since the last century, a series of basic research on spinal cord injury has made us a deep understanding of its mechanisms and pathophysiology. But so far, how to repair damaged nerve functions after SCI is still a neurological problem. There are still controversies surrounding some treatment strategies for SCI, including the use of magnetic resonance imaging, type and timing of anticoagulant prevention, the timing of surgical intervention, the use of corticosteroids such as methylprednisolone sodium, as well as the type and timing of rehabilitation. For patients with SCI, early surgical intervention and neuroprotective therapy may be the best treatment. At the same time, rehabilitation and psychological intervention are equally important.
