Cauda equina: The cauda equina (Latin for "horse's tail") is a bundle of spinal nerves and spinal nerve roots, consisting of the second through fifth lumbar nerve pairs, the first through fifth sacral nerve pairs, and the coccygeal nerve, all of which arise from the lumbar enlargement and the conus medullaris of the spinal cord. The cauda equina occupies the lumbar cistern, a subarachnoid space inferior to the conus medullaris.Spinal tumorLaminectomyCurrarino syndrome: The Currarino syndrome (also Currarino triad) is an inherited congenital disorder where (1) the sacrum (the fused vertebrae forming the back of the pelvis) is not formed properly, (2) there is a mass in the presacral space in front of the sacrum, and (3) there are malformations of the anus or rectum. It can also cause an anterior meningocele or a presacral teratoma.Sacral anterior root stimulator: An implantable medical device enabling patients with a spinal cord lesion to empty their bladders.EpendymomaSpinal decompression: Spinal decompression is the relief of pressure on one or many pinched nerves (neural impingement) of the spinal column.Spinal stenosis: Spinal stenosis is an abnormal narrowing (stenosis) of the spinal canal that may occur in any of the regions of the spine. This narrowing causes a restriction to the spinal canal, resulting in a neurological deficit.Transitional ballistics: Transitional ballistics, also known as intermediate ballistics,Ballistics at Encyclopædia Britannica Online, Accessed April 27, 2009 is the study of a projectile's behavior from the time it leaves the muzzle until the pressure behind the projectile is equalized,Physics 001 The Science of Ballistics accessed Apr 27, 2009 so it lies between internal ballistics and external ballistics.RadiculopathyElectrodiagnosis: Electrodiagnosis is a method of obtaining information about diseases by passively recording the electrical activity of body parts or by measuring their response to external electrical stimulus.Cervical spine disorder: Cervical Spine Disorders are illnesses that are relatively detrimental to ones physical health. These ailments exist in the cervical spine which is made up of the upper first seven vertebrae, encasing and shielding the Spinal cord.Antoni Jan GoetzFalx cerebri: The falx cerebri is also known as the cerebral falx, named from its sickle-like form. It is a large, crescent-shaped fold of meningeal layer of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres.Pseudomeningocele: A pseudomeningocele is an abnormal collection of cerebrospinal fluid (CSF) that communicates with the CSF space around the brain or spinal cord. In contrast to a meningocele, in which the fluid is surrounded and confined by dura mater, in a pseudomeningocele, the fluid has no surrounding membrane but is contained in a cavity within the soft tissues.Gangliocytic paraganglioma: A gangliocytic paraganglioma, abbreviated GP, is a rare tumour that is typically found in the duodenum and consists of three components: (1) ganglion cells, (2) epithelioid cells (paraganglioma-like) and, (3) spindle cells (schwannoma-like).Ballistic traumaLumbar disc disease: Lumbar disc disease is the drying out of the spongy interior matrix of an intervertebral disc in the spine. Many physicians and patients use the term lumbar disc disease to encompass several different causes of back pain or sciatica.HyperintensityUpper motor neuron lesion: An upper motor neuron lesion (also known as pyramidal insufficiency) is a lesion of the neural pathway above the anterior horn cell of the spinal cord or motor nuclei of the cranial nerves. This is in contrast to a lower motor neuron lesion, which affects nerve fibers traveling from the anterior horn of the spinal cord or the cranial motor nuclei to the relevant muscle(s).Diffuse idiopathic skeletal hyperostosisReplantation: Replantation has been defined by the American Society for Surgery of the Hand as "the surgical reattachment of a body part, most commonly a finger, hand or arm, that has been completely cut from a person's body".http://www.ArachnoiditisDysesthesia: Dysesthesia (dysaesthesia) comes from the Greek word "dys", meaning "not-normal" and "aesthesis", which means "sensation" (abnormal sensation). It is defined as an unpleasant, abnormal sense of touch.
