These initial events set off a complex secondary cascade that causes the lesion to expand in size, over a long distance and over a long period of time.Download EndNote 21 - Software manager reference not only frees you from work in collecting and managing research material EndNote:ĮndNote X9 as a researcher, you constantly carry the different roles, addressing the competing demands on your time and coordinate not only the activities of the own in study published that all your collaborators on the whole and on the whole world. White matter axons may also be directly lesioned with the primary injury. There is frank hemorrhage at the injury site and small petechial hemorrhages away from the injury over the next couple of hours. In most cases, the primary injury begins in the gray matter of the cord, when the blood vessels shear and rupture, directly damaging neurons. Commonly, the fractured or dislocated bone compresses the cord or only partially pierces it. It is important to note that the spinal cord is rarely completely severed some spinal cord tissue is usually spared. This direct damage to the spinal cord is called the primary injury. The damaged bony segments impinge the spinal cord and immediately cause a lesion. In fact, fracture, dislocation, and/or subluxation of the vertebrae are the most common causes of SCI. The spinal cord is protected by the surrounding bone of the vertebrae, but in severe trauma, the vertebrae fracture or dislocate.
