Discitis
Discitis, or diskitis, is an infection in the intervertebral disc space that affects different age groups. Symptoms include severe back pain, leading to lack of mobility. In adults, it can lead to severe consequences, such as sepsis or epidural abscess, but it can also spontaneously resolve, especially in children under 8 years of age. Discitis occurs post-surgically in approximately 1–2 percent of patients after spinal surgery. There is debate as to the cause. Diagnosis is usually apparent on MRI, although plain X-rays and CT examinations can be suggestive. Treatment is difficult and usually includes antibiotics. Reducing the mobility of the affected region is an occasionally recommended solution, but changes from case to case. Description Discitis is an infection in the intervertebral disc space. It affects different age groups. Signs and symptoms Symptoms include severe back pain, leading to lack of mobility. In adults, it can lead to severe consequences, such as sepsi ...

Spondylodiscitis
Spondylodiscitis is a combination of discitis (inflammation of one or more intervertebral disc spaces) and spondylitis (inflammation of one or more vertebrae), the latter generally involving the areas adjacent to the intervertebral disc space. Causes Spondylodiscitis is the most common complication of sepsis or local infection, usually in the form of an abscess. The main causative organisms are staphylococci, but potential organisms include a large number of bacteria, fungi, zoonoses. Spondylodiscitis frequently develops in immunocompromised individuals, such as by a cancer, infection, or by immunosuppressive drugs used for organ transplantations. Diagnosis The main methods to diagnose a spondylodiscitis are magnetic resonance imaging Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intervertebral Disc Space
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 ...

Infection
An infection is the invasion of tissue (biology), tissues by pathogens, their multiplication, and the reaction of host (biology), host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an Disease#Terminology, illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently pathogenic bacteria, bacteria and viruses. Hosts can fight infections using their immune systems. Mammalian hosts react to infections with an Innate immune system, innate response, often involving inflammation, followed by an Adaptive immune system, adaptive response. Treatment for infections depends on the type of pathogen involved. Common medications include: * Antibiotics for bacterial infections. * Antivirals for viral infections. * Antifungals for fungal infections. * Antiprotozoals for protozoan infections. * Antihelminthics for infections caused by parasi ...

Ciprofloxacin
Ciprofloxacin is a fluoroquinolone antibiotic used to treat a number of bacterial infections. This includes bone and joint infections, intra-abdominal infections, certain types of infectious diarrhea, respiratory tract infections, skin infections, typhoid fever, and urinary tract infections, among others. For some infections it is used in addition to other antibiotics. It can be taken by mouth, as eye drops, as ear drops, or intravenously. Common side effects include nausea, vomiting, and diarrhea. Severe side effects include tendon rupture, hallucinations, and nerve damage. In people with myasthenia gravis, there is worsening muscle weakness. Rates of side effects appear to be higher than some groups of antibiotics such as cephalosporins but lower than others such as clindamycin. Studies in other animals raise concerns regarding use in pregnancy. No problems were identified, however, in the children of a small number of women who took the medication. It appear ...

Vascularity
Vascularity, in bodybuilding, is the condition of having many highly visible, prominent, and often extensively-ramified superficial veins. The skin appears "thin"—sometimes virtually transparent—due to an extreme reduction of subcutaneous fat, allowing for maximum muscle definition. Vascularity is enhanced by extremely low body fat (usually below 10%) and low retained water, as well as the muscle engorgement ("pump") and venous distension accentuated by the vigorous flexing and potentially hazardous Valsalva effect which characterize competitive posing. Genetics and androgenic hormones will affect vascularity, as will ambient temperature. Additionally, although some bodybuilders develop arterial hypertension from performance-enhancing substances and practices, "high" venous pressure—being an order of magnitude lower than that of arteries— neither causes nor is caused by vascularity. Some bodybuilders use topical vasodilators to increase blood flow to the skin as well. Al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abscess
An abscess is a collection of pus that has built up within the tissue of the body, usually caused by bacterial infection. Signs and symptoms of abscesses include redness, pain, warmth, and swelling. The swelling may feel fluid-filled when pressed. The area of redness often extends beyond the swelling. Carbuncles and boils are types of abscess that often involve hair follicles, with carbuncles being larger. A cyst is related to an abscess, but it contains a material other than pus, and a cyst has a clearly defined wall. Abscesses can also form internally on internal organs and after surgery. They are usually caused by a bacterial infection. Often many different types of bacteria are involved in a single infection. In many areas of the world, the most common bacteria present is ''methicillin-resistant Staphylococcus aureus''. Rarely, parasites can cause abscesses; this is more common in the developing world. Diagnosis of a skin abscess is usually made based on what it looks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plaster Cast
A plaster cast is a copy made in plaster of another 3-dimensional form. The original from which the cast is taken may be a sculpture, building, a face, a pregnant belly, a fossil or other remains such as fresh or fossilised footprints – particularly in palaeontology (a track of dinosaur footprints made in this way can be seen outside the Oxford University Museum of Natural History). Sometimes a blank block of plaster itself was carved to produce mock-ups or first drafts of sculptures (usually relief sculptures) that would ultimately be sculpted in stone, by measuring exactly from the cast, for example by using a pointing machine. These are still described as plaster casts. Examples of these by John Flaxman may be found in the central rotunda of the library at University College London, and elsewhere in the university's collections. It may also describe a finished original sculpture made out of plaster, though these are rarer. Method Plaster is applied to the original ...

Back Brace
A back brace is a device designed to limit the motion of the spine in cases of bone fracture or in post-operative spinal fusiona, as well as a preventative measure against some progressive conditions or to correct a patient's posture. Common back braces include: * Rigid (hard) braces : These braces are form-fitting plastic molds (historically leather) and rigid (typically metal) supports that significantly restrict motion by between 50 and 65% while rotation is limited by up to 70%. * Soft braces : Elastic braces that limit the forward motion of the spine and assist in setting spinal fusions or supporting the spine during occasions of stress (for example, employment requiring the lifting of heavy loads) * Semi rigid braces : Semi-rigid braces combine elements of flexible and rigid braces within one overall design. This is done by adding rigid supports or additional stiff padding and straps to the body of a flexible brace. Sometimes these added rigid supports are removable, allowin ...

Spondyloarthritis
Spondyloarthritis (SpA), also known as spondyloarthropathy, is a collection of syndromes connected by genetic predisposition and clinical symptoms. The best-known subtypes are enteropathic arthritis (EA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), and reactive arthritis (ReA). Symptoms of spondyloarthritis include back pain, arthritis, and enthesitis, inflammation at bone-adhering ligaments, tendons, or joint capsules. Spondyloarthritis is caused by a combination of genetic and environmental factors. It is associated with intestinal inflammation, with a connection between Crohn's disease and ankylosing spondylitis. Reactive arthritis is primarily caused by gastrointestinal, genitourinary, respiratory infections, and genetic factors. Spondyloarthritis is diagnosed based on symptoms and imaging. Early diagnosis criteria use genetic testing and more advanced forms of medical imaging. Spondyloarthritis is categorized into two groups based on the Assessment of Spondyl ...

Spinal 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] |
Spinal Fracture
A spinal fracture, also called a vertebral fracture or a broken back, is a bone fracture, 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 fixation, internal or external fixation. Types *Cervical fracture **Fracture of ''Atlas (anatomy), C1'', including Jefferson fracture **Fracture of ''Axis (anatomy), C2'', including Hangman's fracture **Flexion teardrop fracture – a fracture of the anteroinferior aspect of a Cervical vertebrae, 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 *Vertebral compression fracture, Comp ...

Spinal Tumor
Spinal tumors are neoplasms located in either the vertebral column or the spinal cord. There are three main types of spinal tumors classified based on their location: extradural and intradural (intradural-intramedullary and intradural-extramedullary). Extradural tumors are located outside the dura mater lining and are most commonly metastatic. Intradural tumors are located inside the dura mater lining and are further subdivided into intramedullary and extramedullary tumors. Intradural-intramedullary tumors are located within the dura and spinal cord parenchyma, while intradural-extramedullary tumors are located within the dura but outside the spinal cord parenchyma. The most common presenting symptom of spinal tumors is nocturnal back pain. Other common symptoms include muscle weakness, sensory loss, and difficulty walking. Loss of bowel and bladder control may occur during the later stages of the disease. The cause of spinal tumors is unknown. Most extradural tumors are metastati ...
