Spinal cord concussion in a professional ice hockey player.

Spinal cord concussion (SCC) is an uncommon injury resulting in transient quadriplegia. The pathophysiology of SCC has been related to underlying spinal canal stenosis in many cases, yet is not always identified. The authors present the case of a professional ice hockey player, without evidence of canal compromise, who sustained an SCC during a regulation game after being struck by a puck in the upper cervical spine. The unusual mechanism of injury is discussed along with a comprehensive review of the literature.
