Vertebral Augmentation
Vertebral augmentation, including vertebroplasty and kyphoplasty, refers to similar percutaneous spinal procedures in which bone cement is injected through a small hole in the skin into a fractured vertebra in order to relieve back pain caused by a vertebral compression fracture. After decades of medical research into the efficacy and safety of vertebral augmentation, there is still a lack of consensus regarding certain aspects of vertebroplasty and kyphoplasty. Procedure Vertebroplasty and kyphoplasty are the two most common procedures for spinal augmentation. These medical terms are classical compounds of the suffix '' -plasty'' meaning "molding or shaping surgically" (from Ancient Greek '' plastós'' "molded, formed") and the prefixes '' vertebro-'' "vertebra" (from Latin ''vertebra'' "joint, joint of the spine") and ''kypho-'' "humped; stooping forward" (from Ancient Greek '' kyphos'' "crooked"). Vertebroplasty Vertebroplasty is typically performed by a spine surgeon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percutaneous
{{More citations needed, date=January 2021 In surgery, a percutaneous procedurei.e. Granger et al., 2012 is any medical procedure or method where access to inner organs or other tissue is done via needle-puncture of the skin, rather than by using an "open" approach where inner organs or tissue are exposed (typically with the use of a scalpel). The percutaneous approach is commonly used in vascular procedures such as angioplasty and stenting. This involves a needle catheter getting access to a blood vessel, followed by the introduction of a wire through the lumen (pathway) of the needle. It is over this wire that other catheters can be placed into the blood vessel. This technique is known as the modified Seldinger technique. More generally, "percutaneous", via its Latin roots means, 'by way of the skin'. An example would be percutaneous drug absorption from topical medications. More often, percutaneous is typically used in reference to placement of medical devices using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interventional Radiologist
Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices. Diagnostic IR procedures are those intended to help make a diagnosis or guide further medical treatment, and include image-guided biopsy of a tumor or injection of an imaging contrast agent into a hollow structure, such as a blood vessel or a duct. By contrast, therapeutic IR procedures provide direct treatment—they include catheter-based medicine delivery, medical device placement (e.g., stents), and angioplasty of narrowed structures. The main benefits of IR techniques are that they can reach the deep structures of the body through a body orifice or tiny incision using small needles and wires. This decreases risks, pain, and recovery compared to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extravasation
Extravasation is the leakage of a fluid out of its contained space into the surrounding area, especially blood or blood cells from vessels. In the case of inflammation, it refers to the movement of white blood cells through the capillary wall, into the surrounding tissues. This is known as leukocyte extravasation, also called diapedesis. In the case of cancer metastasis, it refers to cancer cells exiting the capillaries and entering other tissues, where secondary tumors may form. The term is commonly used in a medical context. More specifically, extravasation can refer to: * Extravasation (intravenous) * Extravasation of infusates * Extravasation of irrigation fluid * Extravasation of urine * Leukocyte extravasation * Angiopellosis (non-leukocyte cell extravastion) Irrigation fluid Extravasation of irrigation fluid is the unintended migration of irrigation fluid (e.g., saline) introduced into a human body. This may occur in several types of endoscopic surgery, such as mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Selection Bias
Selection bias is the bias introduced by the selection of individuals, groups, or data for analysis in such a way that proper randomization is not achieved, thereby failing to ensure that the sample obtained is representative of the population intended to be analyzed. It is sometimes referred to as the selection effect. The phrase "selection bias" most often refers to the distortion of a statistical analysis, resulting from the method of collecting samples. If the selection bias is not taken into account, then some conclusions of the study may be false. Types of bias Sampling bias Sampling bias is systematic error due to a non-random sample of a population, causing some members of the population to be less likely to be included than others, resulting in a biased sample, defined as a statistical sample of a statistical population, population (or non-human factors) in which all participants are not equally balanced or objectively represented. It is mostly classified as a subtype of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Lancet
''The Lancet'' is a weekly peer-reviewed general medical journal, founded in England in 1823. It is one of the world's highest-impact academic journals and also one of the oldest medical journals still in publication. The journal publishes original research articles, review articles ("seminars" and "reviews"), editorials, book reviews, correspondence, as well as news features and case reports.

Vertebral Fracture
A spinal fracture, also called a vertebral fracture or a broken back, is a fracture affecting the vertebrae of the spinal column. Most types of spinal fracture confer a significant risk of spinal cord injury. After the immediate trauma, there is a risk of spinal cord injury (or worsening of an already injured spine) if the fracture is ''unstable'', that is, likely to change alignment without internal or external fixation. Types * Cervical fracture **Fracture of '' C1'', including Jefferson fracture **Fracture of '' C2'', including Hangman's fracture ** Flexion teardrop fracture – a fracture of the anteroinferior aspect of a cervical vertebra * Clay-shoveler fracture – fracture through the spinous process of a vertebra occurring at any of the lower cervical or upper thoracic vertebrae *Burst fracture – in which a vertebra breaks from a high-energy axial load * Compression fracture – a collapse of a vertebra, often resulting in the form of a wedge-shape due to larger com ...

Kyphosis
Kyphosis () is an abnormally excessive convex curvature of the Spinal column, spine as it occurs in the Thoracic spine, thoracic and sacrum, sacral regions. Abnormal inward concave ''lordotic'' curving of the Cervical spine, cervical and Lumbar spine, lumbar regions of the spine is called lordosis. It can result from degenerative disc disease; developmental abnormalities, most commonly Scheuermann's disease; Copenhagen disease, osteoporosis with compression fractures of the vertebra; multiple myeloma; or trauma. A normal thoracic spine extends from the 1st thoracic to the 12th thoracic vertebra and should have a slight kyphotic angle, ranging from 20° to 45°. When the "roundness" of the upper spine increases past 45° it is called kyphosis or "hyperkyphosis". Scheuermann's kyphosis is the most classic form of hyperkyphosis and is the result of wedged vertebrae that develop during adolescence. The cause is not currently known and the condition appears to be multifactorial a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
