Epidural space: In the spine, the epidural space (from Ancient Greek ἐπί, "on, upon" + dura mater also known as "epidural cavity", "extradural space" or "peridural space") is an anatomic space that is the outermost part of the spinal canal. It is the space within the canal (formed by the surrounding vertebrae) lying outside the dura mater (which encloses the arachnoid mater, subarachnoid space, the cerebrospinal fluid, and the spinal cord).Combined spinal and epidural anaesthesia: Combined spinal and epidural anaesthesia (CSE) is a regional anaesthetic technique, which combines the benefits of both spinal anaesthesia and epidural anaesthesia and analgesia. The spinal component gives a rapid onset of a predictable block.Clickfine pen needlesFalx 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.Pelvic lipomatosis: The rare disease pelvic lipomatosis is most often seen in older obese black men with hypertension. In pelvic lipomatosis, abnormally dense deposits of otherwise apparently normal fat may be observed in the spaces of the pelvic area.RadiculopathySacral anterior root stimulator: An implantable medical device enabling patients with a spinal cord lesion to empty their bladders.Coccyx fracture: A coccyx fracture is a fracture of the coccyx, commonly called a 'broken tailbone'.Clay-shoveler fracture: Clay-shoveler's fracture is a stable fracture through the spinous process of a vertebra occurring at any of the lower cervical or upper thoracic vertebrae, classically at C6 or C7. In Australia in the 1930s, men digging deep ditches tossed clay 10 to 15 feet above their heads using long handled shovels.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.Hydrogen darkening: Hydrogen darkening is a physical degradation of the optical properties of glass. Free hydrogen atoms are able to bind to the SiO2 silica glass compound forming hydroxyl (OH) - a chemical compound that interferes with the passage of light through the glass.Paracervical block: A paracervical block is an anesthetic procedure used in obstetrics and gynecology, in which a local anesthetic is injected into between two to six sites at a depth of 3–7 mm alongside the vaginal portion of the cervix in the vaginal fornices.paracervical block By Robert Nadelberg.P-adic Hodge theory: In mathematics, p-adic Hodge theory is a theory that provides a way to classify and study p-adic Galois representations of characteristic 0 local fieldsIn this article, a local field is complete discrete valuation field whose residue field is perfect. with residual characteristic p (such as Qp).Orthostatic headache: Orthostatic headache is a medical condition in which a person develops a headache while vertical and the headache is relieved when horizontal.LaminectomyNeuromere: Neuromeres are morphologically or molecularly defined transient segments of the early developing brain. Rhombomeres are such segments that make up the rhombencephalon or hindbrain.Lumbar 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.Local anesthetic: Local anesthetic (LA) is a medication that causes reversible absence of pain sensation, although other senses are often affected as well. Also, when it is used on specific nerve pathways (local anesthetic nerve block), paralysis (loss of muscle power) can be achieved as well.Anesthesia: In the practice of medicine, especially surgery, and dentistry, anesthesia (or anaesthesia) is an induced, temporary state with one or more of the following characteristics: analgesia (relief from or prevention of pain), paralysis (extreme muscle relaxation), amnesia (loss of memory), and unconsciousness. An anesthetic is an agent that causes anaesthesia.Discharge coefficient: In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge) is the ratio of the actual discharge to the theoretical discharge,Sam Mannan, Frank P. Lee, Lee's Loss Prevention in the Process Industries: Hazard Identification, Assessment and Control, Volume 1, Elsevier Butterworth Heinemann, 2005.Balloon catheter: A balloon catheter is a type of "soft" catheter with an inflatable "balloon" at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body. The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed.OhmefentanylBupivacaineCervical fractureDense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.Canine degenerative myelopathy: Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS). Onset is typically after the age of 7 years and it is seen most frequently in the German shepherd dog, Pembroke Welsh corgi, and boxer dog, though the disorder is strongly associated with a gene mutation in SOD1 that has been found in 43 breeds as of 2008, including the wire fox terrier, Chesapeake Bay retriever, Rhodesian ridgeback, and Cardigan Welsh corgi.Endoscopy unit: An endoscopy unit refers to a dedicated area where medical procedures are performed with endoscopes, which are cameras used to visualize structures within the body, such as the digestive tract and genitourinary system. Endoscopy units may be located within a hospital, incorporated within other medical care centres, or may be stand-alone in nature.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.Low back painLidocaine: lignocaineHyperintensitySteroid use in Bollywood: The use of steroids by Bollywood actors has become highlighted in a number of newspaper and web articles where actors and models with previously very thin physiques have in a short period of time developed muscular bodies.Nerve block
