Spinal injury

Spinal cord injury; SCI

The spinal cord contains the nerves that carry messages between your brain and the rest of the body. The cord passes through your neck and back. A spinal cord injury is very serious because it can cause loss of movement (paralysis), function, and sensation below the site of the injury.

    When you get up from a chair or take a walk, do you feel pain in your back, legs, shoulders, or arms? Do your arms or legs feel weaker than usual? If so, believe it or not, the problem could be in your spine, and the cause, a condition known as condition called spinal stenosis. Your spine is the column of bones that runs up the center of your back. It not only helps you stay upright but also flexes to allow you to bend and twist. These bones are called vertebrae, which are separated by spongy disks that cushion the bones so they don't rub against each other. As you get older, these spongy disks start to shrink, while the ligaments of your spine may swell up, due to arthritis. Together, these two actions narrow and put pressure on your spinal cord, or its exiting nerves, which is called spinal stenosis. You can also get spinal stenosis if you've had an injury like a slipped disk. So, how is spinal stenosis diagnosed?During an exam, your doctor will try to find the source of your pain or weakness by having you go through different motions. You'll sit, stand, walk, bend forward and backward, and lift your legs. The doctor will probably also test your reflexes with a rubber hammer, and use a feather or pin to see whether you've lost any feeling in feet and legs. Although there are surgical procedures to relieve the pressure on your spinal cord, trying a few measures at home first can help you avoid surgery. Physical therapy will teach you exercises and stretches to strengthen your muscles and improve your range of motion. Massage and acupuncture can be helpful for relieving back and neck pain. Putting heat or ice on a painful area can also help. Or, your doctor may recommend taking anti-inflammatory or pain-relieving medications. You can probably stay active with spinal stenosis, if you follow your doctor's recommendations and don't try to overdo it. Maybe you need to walk instead of jog, or play fewer holes on the golf course. If treatments at home don't work, surgery can often help relieve your symptoms, although it doesn't cure the condition and your pain may come back afterward. One of the biggest worries with spinal stenosis is numbness. If you can't feel pain in your legs or feet, you may get injured and not even realize it. An untreated injury can lead to an infection. Make sure to call your doctor if you have any numbness, pain, or other symptoms of spinal stenosis, especially trouble balancing or difficulty urinating or having a bowel movement. Take care of your spine. It's the only one you've got.

    Spinal cord injury

    A severe spinal cord injury often causes loss of feeling and paralysis, the loss of movement and voluntary control over the muscles in the body. Spinal cord damage also causes loss of reflex function below the point of injury interrupting bodily functions such as breathing, bowel control, and bladder control. In the event of a spinal injury prompt medical attention can help to minimize further spinal cord damage.

    Lumbar puncture (spinal tap)

    A lumbar puncture, or spinal tap, is a procedure to collect cerebrospinal fluid to check for the presence of disease or injury. A spinal needle is inserted, usually between the third and fourth lumbar vertebrae in the lower spine. Once the needle is properly positioned in the subarachnoid space (the space between the spinal cord and its covering, the meninges), pressures can be measured and fluid can be collected for testing.

    Central nervous system

    The central nervous system is made up of the brain and spinal cord. The brain functions to receive nerve impulses from the spinal cord and cranial nerves. The spinal cord contains the nerves that carry messages between the brain and the body. Spinal cord injury can occur when there is damage to the cells within the spinal cord or when the tracts of nerves that run up and down the spinal cord are severed.

    Cerebral spinal fluid (CSF) is a clear fluid that circulates in the space surrounding the spinal cord and brain. CSF protects the brain and spinal cord from injury by acting like a liquid cushion. CSF is usually obtained through a lumbar puncture (spinal tap). During the procedure, a needle is inserted usually between the 3rd and 4th lumbar vertebrae and the CSF fluid is collected for testing.

    Peripheral Neuropathy is not a distinct disease, but the manifestation of many conditions that damage the peripheral nerves (nervous tissue other than the brain and spinal cord). Symptoms depend on whether sensory nerves (the nerves that transmit sensory information from the body to the brain and spinal cord) or motor nerves (the nerves that transmit impulses from the brain and spinal cord to the body) are affected. If the sensory nerves are damaged, sensation may be diminished, lacking or abnormal. Damaged motor nerves impair movement or function. Peripheral neuropathy may be caused by direct or indirect injury, or by a systemic cause such as a metabolic disorder.
