		Quadriplegia is a Spinal injury that impairs a person from the neck down which impairs a person's ability to breathe, and paralyzes his arms, legs and torso.
		The spinal column is held in alignment by ligaments, cartilage and muscles that surround and protect the spinal cord.
		At times, surgery may be necessary to reduce pressure on the spinal cord or a nerve root when pain is caused by a herniated disk or bony narrowing of the spinal canal.

	Back.com - FAQs - What is spinal stenosis?
		Spinal stenosis is a degenerative arthritic spinal condition that causes pressure on the spinal nerves from a buildup of bone-spurs or spinal ligaments.
		This causes thickening the ligamentum flavum and narrowing of the spinal canal.
		Spinal stenosis is the narrowing of the spinal canal.

	Spinal canal - Wikipedia, the free encyclopedia
		The spinal canal (or vertebral canal) is the space in vertebrae through which the spinal cord passes.
		In the intervertebral spaces, the canal is protected by the ligamentum flavum posteriorly and the posterior longitudinal ligament anteriorly.
		The outermost layer of the meninges, the dura mater, divides the spinal canal into epidural and subdural regions.

	Spinal cord injury: Spinal Stenosis
		A set of symptoms related to narrowing of the spinal canal seen with aging and degeneration is called spinal stenosis.
		These symptoms are related to the irritation of the nerves in the spinal canal which is worsened with standing or walking due to mechanical compression or stretching of the nerves.
		Spinal stenosis refers to the condition of neurologic problems associated with narrowing of the spinal canal due to degenerative changes in the spine.

	Back pain causes - Mechanical Disorders - Stenosis
		Lumbar spinal stenosis is a disease that is caused by a gradual narrowing of the spinal canal.
		Spinal stenosis may be caused by a number of processes that decrease the amount of space in the spinal canal available for the neural elements.
		The presentation and severity of the symptoms of spinal stenosis depends on the several factors, including the original width of the spinal canal, the susceptibility of the nerves involved, and the unique functional demands of the patient and the pain tolerance of each individual patient.

	Congenital Stenosis of the Cervical Spinal Canal
		Congenital stenosis of the cervical spinal canal is the narrowing of the spinal canal in the neck (Fig.
		Spinal cord injury can occur when the neck is forced to bend too far forward or backward or is com-pressed through a blow to the top of the head.
		Athletes who have cervical spinal stenosis and participate in contact sports (e.g., football, martial arts, basketball) are at risk for serious nerve injuries due to pinching within the spinal canal.

	The Physician and Sportsmedicine: Degenerative Lumbar Spinal Stenosis
		Lumbar spinal stenosis is characterized by narrowing of the spinal canal and/or the intervertebral foramina that decreases space for the neural elements.
		The lateral borders of the spinal canal are composed of the pedicles, the bony attachments of the posterior arches to the vertebrae anteriorly.
		CT is used to determine canal dimensions and configuration and to identify disk abnormalities and herniation, facet degeneration and hypertrophy, ligamentous hypertrophy and redundancy, and spondylosis or occult fractures.

	Questions and Answers About Spinal Stenosis (Site not responding. Last check: 2007-10-20)
		Spinal stenosis is a narrowing of spaces in the spine (backbone) that results in pressure on the spinal cord and/or nerve roots.
		Spinal cord/nerve roots—a major part of the central nervous system that extends from the base of the brain down to the lower back and that is encased by the vertebral column.
		The purpose of surgery is to relieve pressure on the spinal cord or nerves and restore and maintain alignment and strength of the spine.
	www.niams.nih.gov /hi/topics/spinalstenosis/spinal_sten.htm (3561 words)

	Spinal Canal Stenosis
		Spinal canal stenosis results from the compression of nerve roots in the spinal canal and develops as a result of a combination of narrowing of the disc space, bulging of the disc into the spinal canal and degeneration of the facet joints.
		The presence of degeneration, a bulging disc or spinal canal stenosis on an X-Ray, CAT scan, MRI scan or myelogram is not an indication to undergo surgery unless these features are shown to be the cause of symptoms that are severe enough to warrant surgical treatment.
		A spinal decompression removes pressure from the nerves by taking away thickened tissue and undercutting the bony structures to enlarge the spinal canal.

	Spinal Stenosis
		Once the narrowing of the spinal canal gets to a critical point, the blood supply to the nerve roots that supply sensation and motor power to the legs is cut off.
		The surgery to widen the spinal canal is termed a "decompression".
		During the procedure, the orthopaedic surgeon removes the laminae (bony arches of the spinal canal), and the ligaments between these arches which may be contributing to the stenosis.

	Penn State Orthopaedics - Spine Services, Lumbar Spinal Stenosis
		Lumbar spinal stenosis is a narrowing of the spinal canal in the lumbar area (low back).
		The surgery to widen the spinal canal is termed a "decompression." The procedure is performed posteriorly through an incision on your back.
		During the procedure the posterior bony arches of the spinal canal (laminae) are removed, as is the ligamentous tissue between these arches which may contribute to the stenosis.

	Lumbar Spinal Stenosis
		Spinal stenosis is narrowing of the spinal canal that occurs when excessive growth of bone and/or tissue reduces the size of the openings in the spinal bones.
		Lumbar spinal stenosis is most commonly caused by age-related changes in the shape and size of the spinal canal.
		These conditions contribute to deterioration of spinal discs, the development of bony growths (spurs), and damage to spinal joints, which in turn may narrow the space in the spinal canal (spinal stenosis).

	[No title]
		Spinal stenosis describes narrowing inside the spinal canal and mainly occurs from a combination of aging and degenerative changes in the spine.
		The spinal canal is a tube within the bones of the spinal column.
		The main goal of any surgical procedure used to treat spinal stenosis is to remove the pressure on the nerve roots in the lumbar spinal canal.

	Spinal cord - Wikipedia, the free encyclopedia
		The Spinal cord nested in the vertebral column.
		Like the brain, the spinal cord is covered by three meninges: the outer dura mater, the arachnoid membrane, and the innermost pia mater, with cerebrospinal fluid found in the subarachnoid space.
		It is important to note that a spinal cord segment is not always found at the same level as its corresponding vertebra, especially in the lower spinal cord segments.

		These are injections of corticosteroid into the epidural space (the area in the spinal canal surrounding the spinal nerves) or facet joints performed by a doctor with special training in this technique.
		Unless significant or progressive leg weakness develops, or bowel or bladder problems occur, the presence of spinal stenosis by itself usually does not represent a dangerous condition in the adult, Therefore, treatment is aimed at pain reduction and increasing the patient's ability to function.
		Since spinal stenosis is a narrowing of the bony canal, the goal of the surgery is to open up the bony canal to improve available space for the nerves.

	Spinal Tap definition - Medical Dictionary definitions of popular medical terms
		Spinal tap: Also known as a lumbar puncture or "LP", a spinal tap is a procedure whereby spinal fluid is removed from the spinal canal for the purpose of diagnostic testing.
		Spinal fluid is sometimes removed by LP for the purpose of decreasing spinal fluid pressure in patients with uncommon conditions (such as, for examples, normal-pressure hydrocephalus and benign intracranial hypertension).
		The values are routinely evaluated during examination of the spinal fluid obtained from the lumbar puncture.

	Spinal Canal Stenosis of the Back
		Spinal Canal Stenosis is a condition in which the canal that the spine runs through compresses narrows to compress the cord itself.
		This canal narrowing can lead to a decreased space for the nerves of the spine to exit, and thus cause a pinching and friction irritation which can lead to pain traveling along the nerve path which exits from the spine and travels down into the leg.
		Spinal canal stenosis can be caused from a congenitally narrowed canal and/or degenerative changes which add bone calcification along the canal.
