		The spinal dura mater is attached to the circumference of the foramen magnum, and to the second and third cervical vertebræ; it is also connected to the posterior longitudinal ligament, especially near the lower end of the vertebral canal, by fibrous slips.
		The spinal part of the subarachnoid cavity is a very wide interval, and is the largest at the lower part of the vertebral canal, where the arachnoid encloses the nerves which form the cauda equina.

	DISEASES OF SPINE (Site not responding. Last check: 2007-11-01)
		Central cavitation is commonly seen with spinal cord tumours, this may be caused by the presence of a high protein content of the cerebral spinal fluid and the expansion of the spinal cord causing reduction in the subarachnoid space and pressure differential.
		The fatty lump infiltrates the parenchyma of the spinal cord.
		Ultrasound of the lumbar region delineates the lump and its attachment to the spinal cord.

		The pedicle was removed and a cavity was created in the vertebral body adjacent to the disk space to curette the disk material away from the spinal cord.
		If the spinal curvature is approached on the concave surface, the disk spaces are narrowed and inaccessible, and the spine is farther away from the chest wall.
		The multisegmental torsional, distractive, and compressive loads that are required during the reduction of severe spinal deformities mandate that fixation be achieved from a posterior approach for complex spinal deformities.

	RSD and Concomitant Neuropathies - Part I
		Edwards and LaRocca[16] reported that a narrow spinal canal in association with a dorsal osteophyte in the spinal canal is a mechanical factor of major clinical significance in CSM.
		These include a herniated intervertebral disc, degenerated hypertrophic facet and uncovertebral joints, and a hypertrophic or calcified ligamentum flavum that may invaginate the spinal canal.[36,54] Of note is that the disc and the ligamentum flavum in the human spine are at approximately the same vertical coordinate level.
		If both are protruding into the spinal canal at the same level, as with extension of the neck, there is a likelihood of significant spinal cord compression.

		It is usually caused by pressure on the sciatic nerve somewhere along its course from the spinal cord in the lower back though the buttocks to the back-and-outer side of the thigh, leg and foot.
		Occasionally, sciatica is caused by bony abnormalities of the vertebrae pressing on the sciatic nerve or narrowing of spinal cavity, called spinal stenosis, that occurs with aging.
		Sciatic caused by spinal stenosis is usually worse when bending backwards or when walking more that 50 to 100 yards.

		Chiari in 1895 postulated that the syringomielia was the persistence of the central conduit of the spinal cord in presence of hydrocephalic.
		The secondary spinal cord cavities, the traumatic hematomielia, the LCR's flow blockade due to compression, glial damage and aracnoídea adherence progression are postulated as pathological mechanisms.

	Dural sealing needle and method of use - Patent 5053046
		Present indications for performing a spinal puncture are the following: (1) diagnosis of bacterial meningitis; (2) diagnosis of mycobacterial and fungal meningitis; (3) diagnosis of subarachnoid hemorrhage; (4) diagnosis of neoplastic meningitis; (5) diagnosis of viral encephalitis; (6) diagnostic study of myelography; (7) diagnostic study of isotope cisternography.
		When the cerebrospinal fluid was removed from the subarachnoid space by spinal tap or subsequent dural leak, the spinal cord was compressed by the pressure gradient with physiological function cessation and/or anatomical injury.
		Another object of the present invention is the provision of an dural sealing apparatus for spinal puncture and sealing which includes a first cannula and a first stylet for performing a spinal puncture, a second cannula and a second stylet in which the second cannula is telescopically insertable into the first cannula.

	Improved cerebral circulation with trepanation
		On the left and the right of the spinal processes of the second and third lumbar vertebrae, the longitudinal muscles of the spine were cut and pulled away from the vertebrae and then an opening made in the body of the third lumbar vertebra.
		The respiratory translocations of CSF recorded on the EPG occur in opposite directions in the cavities of the cerebrum and the spine, i.e., if, during inhalation there is a decrease in electrical resistance of the cranio-cerebral cavity and simultaneously an increase in the spinal cavity.
		Since the speed of volume CSF translocations between the brain and the spine cavities is limited, rapid changes in the blood supply of the cranio-cerebral cavity are compensated for by re-redistribution between the CSF and the venous blood in the cranial cavity.

	OCR Document
		Inside cranial cavity alternating component of arterial pressure is transmitting to venous blood outflow, using CSF pressure and volume pulse fluctuations.
		Biophysical relations between liquid media inside cranial cavity are very important for intracranial blood volume compensation, which are necessary for active responses of cerebral blood vessels due to action of control mechanisms.
		With purpose of monitoring of changes in CSF movements, inside cranium and between cranial and spinal cavities, it is reasonable to use bi-mastoidal position of electrodes, which allows to observe simultaneously changes in both hemispheres.

		Factors related to initial cavity formation include liquefaction of intraparenchymal hematoma, ischemia due to tethering, arterial or venous obstruction, release of intracellular lysosomal enzymes and excitatory amino acids, and mechanical damage from cord compression.
		Tethering of the spinal cord, which results in impaired CSF circulation around the traumatized segment of spinal cord, occurs as a sequela of bleeding-induced arachnoiditis, scarring, spinal canal stenosis, or kyphotic deformity.
		CT-myelography delineates the extent of the syrinx cavity, arachnoid scarring, and tethering of the spinal cord.

	Re: Re: Re: Myelomalacia
		A contusion or bruise of the spinal cord from trauma is a very common way for this problem to happen.
		If a cyst or syrinx forms and starts affecting normal areas of the spinal cord, a small tube or shunt can be placed into the affected area to drain the cyst or syrinz and alleviate the pressure and damage it is causing.

		Pressure on the lower part of the spinal cord or on nerve roots branching out from that area may give rise to pain or numbness in the legs.
		Pressure on the upper part of the spinal cord (that is, the neck area) may produce similar symptoms in the shoulders, or even the legs.

		A spinal tap (lumbar puncture) is another procedure the doctor may order to diagnose leukemia.
		In this procedure, a small needle is inserted into the spinal cavity in the lower back to withdraw some cerebrospinal fluid and to look for leukemic cells.
		Standard imaging tests such as x rays may be used to check whether the leukemic cells have invaded other areas of the body, such as the bones, chest, kidneys, abdomen, or brain.

	Spina bifida (Site not responding. Last check: 2007-11-01)
		Spina bifida is a serious birth abnormality in which the spinal cord is malformed and lacks its usual protective skeletal and soft tissue coverings.
		In rare instances, the spinal cord malformation may occur internally, sometimes with a connection to the gastrointestinal tract.
		Subsequent surgery is often necessary to protect against excessive curvature of the spine, and in the presence of hydrocephaly, to place a mechanical shunt to decrease the pressure and amount of cerebrospinal fluid in the cavities of the brain.

	Spinal Tracts
		The spinal cord has two general functions: 1) It provides the two-way conduction routes to/from (afferent/efferent) the brain; and 2) it serves as the reflex center for all spinal reflexes.
		Each nerve has two roots connecting to the spinal cord: The posterior (dorsal) is the sensory root; the anterior (ventral) is the motor root.
		The simplest spinal reflex is the tendon reflex, a monosynaptic reflex.

	The Spinal Tap Procedure
		The definitive test for EPM is considered to be the Western Blot test or the spinal fluid test (CSF), which is where spinal fluid is tested for the antibodies that will be produced if the horse is actively infected by Sarcocystis neurona, the protozoal organism responsible for EPM.
		The spinal tap involves inserting a long needle into the horse's spinal cavity and withdrawing a sample of the spinal fluid.
		For example, if the horse appears to get better with the treatment, and has not had a spinal fluid test, the owner may decide the horse doesn't really have EPM at all and stop the treatment before it has had time to be completely effective.
