Quadriplegia
Medical Questions » Quadriplegia
| Name: Quadriplegia |
| Also known as: Tetraplegia |
| Complication of a neck injury that severs the spinal cord. |
Causes of Quadriplegia
All parts of the human body are capable of healing and repairing damage, except the central nervous system, which comprises the brain and spinal cord. The spinal cord runs from the base of the brain, down through the vertebrae that form the backbone, and ends just below the waist. Nerves run out from it to the muscles, skin and other tissues, with one bundle of nerves emerging from between each of the 24 vertebrae. If the spinal cord is cut by a broken neck or other injury, it is impossible for nerve signals to pass backwards and forwards from the brain to the body. Involuntary muscles which control the internal organs such as the gut and heart movements, are supplied by a different set of nerves, and are not affected by spinal injury. |
Symptoms of Quadriplegia
Paralysis from the neck down. Patients cannot feel heat or cold, hard or soft, sharp or dull, or any sensation below the level of the injury. There is no control of muscles, so patients cannot walk, move their arms or control their bowels or bladder. |
Tests for Quadriplegia
Diagnosed by X-rays, CT and MRI scans, and electrical tests on nerves and muscles. |
Treatment for Quadriplegia
The only help that can be offered is rehabilitation so patients can cope with their disability.
|
Complications of Quadriplegia of its treatment
Pressure sores on the skin, and lung and urinary infections from immobility. |
Likely Outcome of Quadriplegia
No cure. Life span often slightly shortened by lung complications. |
