IDET2007 StB Steam Envelope Opener
The term intervertebral disc annuloplasty indicates any procedure aimed at repairing the annulus of a bulging intervertebral disc before it herniates. Intradiscal electrothermal annuloplasty IDET ("Intradiscal Electrothermal Annuloplasty") is a recently developed minimally invasive form of annuloplasty consisting of the insertion in the affected disc of a hollow needle, through which a heating wire is passed; once this has reached the disc, the wire is heated to 90 °C for approximately fifteen minutes. The heat is intended to seal any ruptures in the disc wall and may also burn nerve endings, which can make the area less sensitive to pain. See also *Disc biacuplasty Disk biacuplasty is a medical procedure that applies heat to the annulus of disks that separate the vertebra of the back with the goal of ablating the neurons that generate pain sensations. The procedure is designed to reduce chronic back pai ... References Neurosurgery {{surgery-stub ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Annulus Fibrosus Disci Intervertebralis
An intervertebral disc (or intervertebral fibrocartilage) 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 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 collagen, 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 concentrations which could cause damage to the under ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Spinal Disc Herniation
Spinal disc herniation is an injury to the cushioning and connective tissue between 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 treatment may range from painkillers to surgery. Protection from disc herniation is best provided by core strength and an awareness of body mechanics including 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 posterior longitudinal lig ...

Minimally Invasive Procedure
Minimally invasive procedures (also known as minimally invasive surgeries) encompass surgical techniques that limit the size of incisions needed, thereby reducing wound healing time, associated pain, and risk of infection. Surgery by definition is invasive and many operations requiring incisions of some size are referred to as ''open surgery''. Incisions made during open surgery can sometimes leave large wounds that may be painful and take a long time to heal. Advancements in medical technologies have enabled the development and regular use of minimally invasive procedures. For example, endovascular aneurysm repair, a minimally invasive surgery, has become the most common method of repairing abdominal aortic aneurysms in the US as of 2003. The procedure involves much smaller incisions than the corresponding open surgery procedure of open aortic surgery. Interventional radiologists were the forerunners of minimally invasive procedures. Using imaging techniques, radiologists wer ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Disc Biacuplasty
Disk biacuplasty is a medical procedure that applies heat to the annulus of disks that separate the vertebra of the back with the goal of ablating the neurons that generate pain sensations. The procedure is designed to reduce chronic back pain caused by the intervertebral discs. The procedure is in the early stages of testing with some evidence of efficacy. As possible advantages to conventional techniques, the developers of the procedure cite its ease of use and a lack of artificial concentric fissures. The procedure may destroy pain nerves without damaging nearby tissues, though evidence for this comes only from studies with cadavers. Testing on pigs suggested it heats the desired area without damaging the dorsal root ganglia or spinal nerve roots, though the cells of the disc demonstrate histological Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the m ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
