Spinal decompression: Spinal decompression is the relief of pressure on one or many pinched nerves (neural impingement) of the spinal column.Decompression (diving): The decompression of a diver is the reduction in ambient pressure experienced during ascent from depth. It is also the process of elimination of dissolved inert gases from the diver's body, which occurs during the ascent, during pauses in the ascent known as decompression stops, and after surfacing until the gas concentrations reach equilibrium.In-water recompression: In-water recompression (IWR) or underwater oxygen treatment is the emergency treatment of decompression sickness (DCS) of sending the diver back underwater to allow the gas bubbles in the tissues, which are causing the symptoms, to resolve. It is a risky procedure that should only ever be used when the time to travel to the nearest recompression chamber is too long to save the victim's life.Saturation diving: Saturation diving is a diving technique that allows divers to reduce the risk of decompression sickness ("the bends") when they work at great depths for long periods of time.LaminectomyMicrovascular decompression: Microvascular decompression (MVD), also known as the Jannetta procedure,http://neurosurgery.ucsf.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.Arnold–Chiari malformationInterbody fusion cage: An interbody fusion cage (colloquially known as a "spine cage") is a prosthesis used in spinal fusion procedures to maintain foraminal height and decompression. They are cylindrical or square-shaped devices, and usually threaded.Cervical fractureSyringomyeliaAir embolismNoble gas compoundLumbar 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.SpondylosisC14 Timberwolf: The C14 Timberwolf MRSWS (Medium Range Sniper Weapon System) is a bolt action sniper rifle built by the Canadian arms company PGW Defence Technologies Inc. In 2005 they won the contract to supply the Canadian Forces Land Command with the C14 Timberwolf MRSWS for $4.DiscectomyClay-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.Richard A Neubauer: Richard Allen Neubauer (16 January 1924–11 June 2007), was a physician known for his work in the use of hyperbaric oxygen therapy.ExophthalmosInfiltrative ophthalmopathy: Infiltrative ophthalmopathy is found in Graves disease and resembles exophthalmos, except that the blurry or double vision is acquired because of weakness in the ocular muscles of the eye. In addition, there is no known correlation with the patient's thyroid levels.Superior orbital fissure: The superior orbital fissure is a foramen in the skull, although strictly it is more of a cleft, lying between the lesser and greater wings of the sphenoid bone.Non-progressive late-onset linear hemifacial lipoatrophy: Non-progressive late-onset linear hemifacial lipoatrophy is a cutaneous condition that occurs on the malar cheek, mostly in the elderly population.RadiculopathyChen Zhongwei: Chen Zhongwei (Chinese:陈中伟, 1929–2004) was an expert of orthopedic surgery and microsurgery, one of the pioneers of the process of reattaching severed limbs.Traumatic spondylopathyArcoCanine 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.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.Currarino 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.Atmospheric-pressure laser ionization: Atmospheric pressure laser ionization is an atmospheric pressure ionization method for mass spectrometry (MS). Laser light in the UV range is used to ionize molecules in a resonance-enhanced multiphoton ionization (REMPI) process.PlatybasiaSpondylolisthesisAbdominal compartment syndrome: (non-traumatic); (traumatic)Helium-3Adson's signClivus (anatomy): The clivus (Latin for "slope") is a part of the cranium at the skull base, a shallow depression behind the dorsum sellæ that slopes obliquely backward. It forms a gradual sloping process at the anterior most portion of the basilar occipital bone at its junction with the sphenoid bone.ParamethasoneBalloonSubmarine Escape Immersion Equipment: Submarine Escape Immersion Equipment (SEIE), also known as Submarine Escape and Immersion Equipment, is a whole-body suit and one-man life raft, designed by British company RFD Beaufort Limited, that allows submariners to escape from a sunken submarine. The suit provides protection against hypothermia and is rapidly replacing the Steinke hood rescue device.Physical Therapy/Occupational therapy in carpal tunnel syndromeEndoscopy 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.Cubital tunnel: The cubital tunnel is a channel which allows the ulnar nerve to travel over the elbow. It is bordered by the medial epicondyle of the humerus, the olecranon process of the ulna and the tendinous arch joining the humeral and ulnar heads of the flexor carpi ulnaris.HyperintensityFalx 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.Bifrontal craniotomy: a bifrontal craniotomy is a surgical process which is used to target different tumors or malfunctioning areas of the brain.http://www.United Airlines Flight 811Journal of Minimal Access Surgery: Journal of Minimal Access Surgery (ISSN: Print - 0972-9941, Online - 1998-3921) is peer-reviewed open access journal published on behalf of the Indian Association of Gastrointestinal Endo Surgeons. The journal publishes articles on the subject of Laparoscopic and thoracoscopic surgery, laparoscopic urology and gastrointestinal endoscopy.Impingement syndromeAnterior atlantooccipital membrane: The anterior atlantooccipital membrane (anterior atlantooccipital ligament) is broad and composed of densely woven fibers, which pass between the anterior margin of the foramen magnum above, and the upper border of the anterior arch of the atlas below.List of people with paraplegia: This is a list of people who have or had paraplegia.Demineralized freeze dried bone allograft: Demineralized freeze dried bone allograft, referred to as DFDBA, is a bone graft material known for its [novo] bone formation properties.Bowers, GM, et al.Divisions of the American Psychological Association: The American Psychological Association offers 54 active divisions, based upon popular areas of expertise within psychology. These divisions are:ArthroscopySulcus sign: The Sulcus sign is an orthopedic evaluation test for glenohumeral instability of the shoulder. With the arm straight and relaxed to the side of the patient, the elbow is grasped and traction is applied in an inferior direction.Herbert screw: The Herbert screw (invented by Timothy Herbert) is a variable pitch cannulated screw typically made from titanium for its stainless properties as the screw is normally intended to remain in the patient indefinitely. It became generally available in 1978.Dense 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.Spinal fractureTarsal tunnel: The tarsal tunnel is found along the inner leg posterior to the medial malleolus.Waldeyer's fascia: The Waldeyer's fascia is synonymous with the presacral fascia and is more commonly described in surgery textbooks, rather than in anatomy textbooks. Although Waldeyer himself did not actually describe this exact anatomy, it is credited to him as he was the first to describe the anatomy of pelvic fascia in detail.Ambesh maneuver: Ambesh maneuver is a technique that involves the simple external compression of internal jugular vein in supraclavicular fossa to prevent and diagnose misplacement of the subclavian vein catheter into the internal jugular vein (IJV). The subclavian vein is a big vessel that drains the blood from the hand, forearm and the upper arm into the right side of the heart through superior vena cava.Volumetric heat capacity: Volumetric heat capacity (VHC), also termed volume-specific heat capacity, describes the ability of a given volume of a substance to store internal energy while undergoing a given temperature change, but without undergoing a phase transition. It is different from specific heat capacity in that the VHC is a 'per unit volume' measure of the relationship between thermal energy and temperature of a material, while the specific heat is a 'per unit mass' measure (or occasionally per molar quantity of the material).Pulmonary volutrauma: Pulmonary volutrauma — Volutrauma is essentially damage to the lung caused by overdistention by a mechanical ventilator set for an excessively high tidal volume; resulting in a syndrome similar to adult respiratory distress syndrome. Volutrauma is separate from Pulmonary barotrauma because the mechanism of injury is excessive volume (volutrauma), instead of pressure (barotrauma).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.Transpulmonary pressure: Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the lungs. During human ventilation, air flows because of pressure gradients.Cholecystostomy
