This results not only in the disconnection of the root from the cord but also in a longitudi- nal spinal cord injury. The complexity of the injury leads to degen- eration of the spinal root and a marked inflammatory response of the spinal cord followed by the formation of a glial scar （Kachra- manoglou et al., 2011）.展开更多
