	Spinal stenosis
		Cervical spinal stenosis is a narrowing of the vertebrae of the neck (cervical vertebrae).
		Spinal stenosis causes pain in the buttocks, thigh, and calf and increasing weakness in the legs.
		Spinal stenosis can be a progressive disease, however, and the source of pressure may have to be surgically removed (surgical decompression) if the patient is losing control over bladder and bowel functions.

	Spinal stenosis symptoms, diagnosis and treatment
		In lumbar spinal stenosis, the spinal cord or spinal nerve roots are compressed, or choked, and this can produce symptoms of pain, tingling, weakness or numbness that radiates into the buttocks and legs.
		Spinal stenosis is related to degeneration in the spine and usually will become significant in the 5th decade of life and extend throughout every subsequent age group.
		Central spinal stenosis is more common at the second lowest lumbar spinal level and above and is largely caused by redundancy of a ligament (ligamentum flavum) which is associated with protecting the dura and arises from the inside part of the facet joint.

	Spinal Stenosis - Causes, Symptoms & Treatment
		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.
		Other researchers are exploring why spinal cord changes lead to a decreased pain threshold or an increased sensitivity to pain, and how fractures of the spine and their repair affect the spinal canal and intervertebral foramen.

	Spinal cord injury: 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.
		Since patients affected by spinal stenosis are usually elderly, treatment must carefully consider not only the disease in the spine but also the risks and benefits of treatment in each individual.

	Patient Education - Spinal Stenosis
		Spinal stenosis (or narrowing) is a common condition that occurs when the small spinal canal that contains the nerve roots and spinal cord becomes restricted.
		Spinal stenosis is typically the result of osteoarthritis causing a pinching of the spinal cord.
		This “acquired spinal stenosis” can occur from the narrowing of the space around the spinal cord due to bony overgrowth from osteoarthritis combined with thickening of one of the ligaments in the back, and a bulge of the intervertebral discs.

	Lumbar Spinal Stenosis-Topic Overview
		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.
		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).
		A diagnosis of lumbar spinal stenosis usually is based on your history of symptoms, a physical examination, and imaging tests, such as magnetic resonance imaging (MRI), computed tomography (CT) scanning, and sometimes X-rays.

		Lateral spinal stenosis generally results in symptoms that are directly related to compression of the nerve roots at the level of the stenosis.
		In the central cervical spinal region, hypertrophy of the ligamentum flavum, bony spondylitic hypertrophy, and bulging of the disc annulus contribute to development of central spinal stenosis.
		Spinal stenosis is demonstrated at several levels (white and yellow arrows) resulting from a combination of disc annulus bulging (white arrow) and epidural soft tissue thickening (yellow arrow).

		Spinal stenosis refers to narrowing of the spinal canal which causes pressure on the spinal nerves or cord.
		The congenital form of spinal stenosis is seen in individuals who are born with a narrow spinal canal.
		The more common acquired form of stenosis is caused by progressive changes in different spinal elements (such as the discs, joints, ligaments, etc.) As people age, all these different elements sag or bulge and form arthritis that narrows the spinal canal.

	Spinal stenosis
		The main cause of spinal degeneration is osteoarthritis, an arthritic condition that affects the cartilage that cushions the ends of bones in your joints.
		Spinal stenosis is especially likely if you have leg pain that gets worse when you walk and improves when you sit or bend forward.
		Spinal stenosis can be difficult to diagnose because its signs and symptoms are often intermittent and because they resemble those of many age-related conditions.

		Spinal stenosis is like the lime build-up on the inside of a garden hose.
		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 Stenosis - Lumbar and Cervical
		Spinal stenosis is a narrowing of the spinal canal, which places pressure on the spinal cord.

		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.
		Although not a common cause of spinal stenosis, damage to ligaments, bones, and joints that begins as synovitis (inflammation of the synovial membrane which lines the inside of the joint) has a severe and disrupting effect on joint function.
		In many cases, the conditions causing spinal stenosis cannot be permanently altered by nonsurgical treatment, even though these measures may relieve pain for a period of time.

	Dr. Spine: What is Spinal Stenosis?
		Stenosis is derived from the Greek meaning, ''narrowing of a normally larger opening.'' The term 'stenosis' is widely used in medicine for different parts of the body.
		The end result in many of these problems is spinal stenosis on the left, right, central, or all of the above, at any one given joint segment, primarily in the lumbar spine.
		This leads us to ask, ''what does spinal stenosis effect, or what effects does spinal stenosis have?'' Primarily we are looking at the central part of the dural sac and/or the right and left nerve roots that exit between the two vertebral bodies.

		Spinal stenosis is a narrowing of one or more areas in your spine — most often in your upper or lower back.
		In general, spinal stenosis can cause cramping, pain or numbness in your legs, back, neck, shoulders or arms; a loss of sensation in your extremities; and sometimes problems with bladder or bowel function.
		Mild symptoms of spinal stenosis are often helped by pain relievers, physical therapy or a supportive brace.

		Lumbar spinal stenosis is a narrowing of the spinal canal in the lumbar area (low back).
		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.
		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.

		Spinal stenosis refers to narrowing of the spinal canal, nerve root canals, or intervertebral foramina due to spondylosis and degenerative disk disease.
		The compressed disks result in shortening of the spinal column, which causes the ligamentum flavum to buckle inward and compress the spinal sac and nerve roots.
		If the stenosis is severe enough, or if it is positioned centrally in the spine, patients may present with signs and symptoms of myelopathy (spinal cord dysfunction).
