Microdiscectomy
A discectomy (also called open discectomy, if done through a 1/2 inch or larger skin opening) is the surgical removal of abnormal disc material that presses on a nerve root or the spinal cord. The procedure involves removing a portion of an intervertebral disc, which causes pain, weakness or numbness by stressing the spinal cord or radiating nerves. The traditional open discectomy, or Love's technique, was published by Ross and Love in 1971. Advances have produced visualization improvements to traditional discectomy procedures (e.g. microdiscectomy, an open discectomy using an external microscope typically done through a 1-inch or larger skin opening), or endoscopic discectomy (the scope passes internally and typically done through a 2 mm skin opening or larger, up to 12 mm). In conjunction with the traditional discectomy or microdiscectomy, a laminotomy is often involved to permit access to the intervertebral disc. Laminotomy means a significant amount of typically nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Disc Herniation
A disc herniation or spinal disc herniation is an injury to the intervertebral disc between two vertebrae, usually caused by excessive strain or trauma to the spine. It may result in back pain, pain or sensation in different parts of the body, and physical disability. The most conclusive diagnostic tool for disc herniation is MRI, and treatments may range from painkillers to surgery. Protection from disc herniation is best provided by core strength and an awareness of body mechanics including good posture. When a tear in the outer, fibrous ring of an intervertebral disc allows the soft, central portion to bulge out beyond the damaged outer rings, the disc is said to be herniated. Disc herniation is frequently associated with age-related degeneration of the outer ring, known as the '' annulus fibrosus'', but is normally triggered by trauma or straining by lifting or twisting. Tears are almost always posterolateral (on the back sides) owing to relative narrowness of the post ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Failed Back Surgery Syndrome
Failed back syndrome (abbreviated as FBS) is a condition characterized by chronic pain following back surgeries. The term "post-laminectomy syndrome" is sometimes used by doctors to indicate the same condition as failed back syndrome. Many factors can contribute to the onset or development of FBS, including residual or recurrent spinal disc herniation, persistent post-operative pressure on a spinal nerve, altered joint mobility, joint hypermobility with instability, scar tissue (fibrosis), depression, anxiety, sleeplessness, spinal muscular deconditioning and ''Cutibacterium acnes'' infection. An individual may be predisposed to the development of FBS due to systemic disorders such as diabetes, autoimmune disease and peripheral vascular disease. Signs and symptoms Common symptoms of failed back syndrome include diffuse, dull, and aching pain in the back or legs, often accompanied by abnormal sensations such as sharp, pricking, or stabbing pain in the extremities. Patients ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intervertebral Disc
An intervertebral disc (British English), also spelled intervertebral disk (American English), lies between adjacent vertebrae in the vertebral column. Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine. Structure Intervertebral discs consist of an outer fibrous ring, the ''anulus (or annulus) fibrosus disci intervertebralis'', which surrounds an inner gel-like center, the ''nucleus pulposus''. The ''anulus fibrosus'' consists of several layers (laminae) of fibrocartilage made up of both type I and type II collagen. Type I is concentrated toward the edge of the ring, where it provides greater strength. The stiff laminae can withstand compressive forces. The fibrous intervertebral disc contains the ''nucleus pulposus'' and this helps to distribute pressure evenly across the disc. This prevents the development of stress conc ...

Degenerative Disc Disease
Degenerative disc disease (DDD) is a medical condition typically brought on by the aging process in which there are anatomic changes and possibly a loss of function of one or more intervertebral discs of the vertebral column, spine. DDD can take place with or without symptoms, but is typically identified once symptoms arise. The root cause is thought to be loss of soluble proteins within the fluid contained in the disc with resultant reduction of the oncotic pressure, which in turn causes loss of fluid volume. Normal downward forces cause the affected disc to lose height, and the distance between vertebrae is reduced. The Intervertebral disc, anulus fibrosus, the tough outer layers of a disc, also weakens. This loss of height causes laxity of the longitudinal ligaments, which may allow anterior, posterior, or lateral shifting of the vertebral bodies, causing facet joint malalignment and arthritis; scoliosis; Cervical vertebrae, cervical hyperlordosis; thoracic hyperkyphosis; lumbar ...

Neurosurgery
Neurosurgery or neurological surgery, known in common parlance as brain surgery, is the specialty (medicine), medical specialty that focuses on the surgical treatment or rehabilitation of disorders which affect any portion of the nervous system including the Human brain, brain, spinal cord, peripheral nervous system, and cerebrovascular system. Neurosurgery as a medical specialty also includes non-surgical management of some neurological conditions. Education and context In different countries, there are different requirements for an individual to legally practice neurosurgery, and there are varying methods through which they must be educated. In most countries, neurosurgeon training requires a minimum period of seven years after graduating from medical school. United Kingdom In the United Kingdom, students must gain entry into medical school. The MBBS qualification (Bachelor of Medicine, Bachelor of Surgery) takes four to six years depending on the student's route. The newly qu ...

Contraindication
In medicine, a contraindication is a condition (a situation or factor) that serves as a reason not to take a certain medical treatment due to the harm that it would cause the patient. Contraindication is the opposite of indication, which is a reason to use a certain treatment. Absolute contraindications are contraindications for which there are no reasonable circumstances for undertaking a course of action (that is, overriding the prohibition). For example: * Children and teenagers with viral infections should not be given aspirin because of the risk of Reye syndrome. * A person with an anaphylactic food allergy should never eat the food to which they are allergic. * A person with hemochromatosis should not be administered iron preparations. * Some medications are so teratogenic that they are absolutely contraindicated in pregnancy; examples include thalidomide and isotretinoin. Relative contraindications are contraindications for circumstances in which the patient is at hig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
