Falling as a part of recreational activities can<unk>  spinal cord injuries. Spinal cord injuries are most often<unk> d by physical trauma. Forces involved can be hyperflexion (forward movement of the head); hyperextension (backward movement); lateral stress (sideways movement); rotation (twisting of the head); compression (force along the axis of the spine downward from the head or upward from the pelvis); or distraction (pulling apart of the vertebrae). Traumatic SCI can result in contusion, compression, or stretch injury. It is a major risk of many types of vertebral fracture. Pre-existing asymptomatic congenital anomalies can<unk>  major neurological deficits, such as hemiparesis, to result from otherwise minor trauma. In the US, Motor vehicle accidents are the most common<unk>  of SCIs; second are falls, then violence such as gunshot wounds, then sports injuries. In some countries falls are more common, even surpassing vehicle crashes as the leading<unk>  of SCI. The rates of violence-related SCI depend heavily on place and time. Of all sports-related SCIs, shallow water dives are the most common<unk> ; winter sports and water sports have been increasing as<unk> s while association football and trampoline injuries have been declining. Hanging can<unk>  injury to the cervical spine, as may occur in attempted suicide. Military conflicts are another<unk> , and when they occur they are associated with increased rates of SCI. Another potential<unk>  of SCI is iatrogenic injury,<unk> d by an improperly done<unk>  procedure such as an injection into the spinal column. SCI can also be of a nontraumatic origin. Nontraumatic lesions<unk>  anywhere from 30 to 80% of all SCI; the percentage varies by locale, influenced by efforts to prevent trauma. Developed countries have higher percentages of SCI due to degenerative conditions and tumors than developing countries. In developed countries, the most common<unk>  of nontraumatic SCI is degenerative diseases, followed by tumors; in many developing countries the leading<unk>  is infection such as HIV and tuberculosis. SCI may occur in intervertebral disc disease, and spinal cord vascular disease. Spontaneous bleeding can occur within or outside of the protective membranes that line the cord, and intervertebral disks can herniate. Damage can result from dysfunction of the blood vessels, as in arteriovenous malformation, or when a blood clot becomes lodged in a blood vessel and cuts off blood supply to the cord. When systemic blood pressure drops, blood flow to the spinal cord may be reduced, potentially<unk> ng a loss of sensation and voluntary movement in the areas supplied by the affected level of the spinal cord. Congenital conditions and tumors that compress the cord can also<unk>  SCI, as can vertebral spondylosis and ischemia. Multiple sclerosis is a disease that can damage the spinal cord, as can infectious or inflammatory conditions such as tuberculosis, herpes zoster or herpes simplex, meningitis, myelitis, and syphilis.
