World Osteoporosis Day: World Osteoporosis Day is observed annually on 20 October, and launches a year-long campaign dedicated to raising global awareness of the prevention, diagnosis and treatment of osteoporosis and metabolic bone disease. Organized by the International Osteoporosis Foundation (IOF), World Osteoporosis Day involves campaigns by national osteoporosis patient societies from around the world with activities in over 90 countries.DenosumabQuantitative computed tomographyFRAX: FRAX is a diagnostic tool used to evaluate the 10-year probability of bone fracture risk. It was developed by the World Health Organization Collaborating Centre for Metabolic Bone Diseases at Sheffield University.Chalkstick fracture: Chalkstick fractures are fractures, typically of long bones, in which the fracture is transverse to the long axis of the bone, like a broken stick of chalk. A healthy long bone typically breaks like a hard woody stick as the collagen in the matrix adds remarkable flexibility to the mineral and the energy can run up and down the growth rings of bone.Zoledronic acidAlendronic acidCancellous bone: Cancellous bone, synonymous with trabecular bone or spongy bone, is one of two types of osseous tissue that form bones. The other osseous tissue type is cortical bone also called compact bone.TeriparatideSpinal fractureRisedronic acidDeoxypyridinolineFemoral neck targeting: Femoral neck targeting is the process of calculating the centre of the femoral neck during hip resurfacing surgery.Comis MIHR operative technique This can be done by hand or using electronic aides.Hip fractureOsteoclastCalcaneal fractureCalcium deficiency (plant disorder): Calcium (Ca) deficiency is a plant disorder that can be caused by insufficient calcium in the growing medium, but is more frequently a product of low transpiration of the whole plant or more commonly the affected tissue. Plants are susceptible to such localized calcium deficiencies in low or nontranspiring tissues because calcium is not transported in the phloem.OsteoblastVitamin DSelective estrogen-receptor modulator: Selective estrogen receptor modulators (SERMs) are a class of compounds that act on the estrogen receptor. A characteristic that distinguishes these substances from pure receptor agonists and antagonists is that their action is different in various tissues, thereby granting the possibility to selectively inhibit or stimulate estrogen-like action in various tissues.OssificationProcalcitonin: Procalcitonin (PCT) is a peptide precursor of the hormone calcitonin, the latter being involved with calcium homeostasis. It is composed of 116 amino acids and is produced by parafollicular cells (C cells) of the thyroid and by the neuroendocrine cells of the lung and the intestine.QRISK: QRISK2 (the most recent version of QRISK) is a prediction algorithm for cardiovascular disease (CVD) that uses traditional risk factors (age, systolic blood pressure, smoking status and ratio of total serum cholesterol to high-density lipoprotein cholesterol) together with body mass index, ethnicity, measures of deprivation, family history, chronic kidney disease, rheumatoid arthritis, atrial fibrillation, diabetes mellitus, and antihypertensive treatment.EstrogenParathyroid hormone family: The parathyroid hormone family is a family of structurally and functionally related proteins. Parathyroid hormone (PTH) is a polypeptidic hormone primarily involved in calcium metabolism.Bone pathology: Bone pathology, also known as orthopedic pathology is a subspecialty of surgical pathology which deals with the diagnosis and feature of many bone diseases. It uses gross and microscopic findings along with the findings of in vivo radiological studies, and occasionally, specimen radiographs to diagnose diseases of the bones.Osteoprotegerin: Osteoprotegerin (OPG), also known as osteoclastogenesis inhibitory factor (OCIF), or tumor necrosis factor receptor superfamily member 11B (TNFRSF11B), is a protein that in humans is encoded by the TNFRSF11B gene. Osteoprotegerin is a cytokine receptor, and a member of the tumor necrosis factor (TNF) receptor superfamily.Microdensitometer: A microdensitometer is an optical instrument used to measure optical densities in the microscopic domain.J.Inguinal ligament: The inguinal ligament (Poupart's ligament) is a band running from the pubic tubercle to the anterior superior iliac spine. Its anatomy is very important for operating on hernia patients.Elevated alkaline phosphataseSquittenN-terminal telopeptide: In bone physiology, the N-terminal telopeptide (or more formally, amino-terminal collagen crosslinks, and known by the acronym NTX) is a [that can be used as a biomarker] to measure the rate of [[bone turnover. NTX can be measured in the urine (uNTX) or serum (serum NTX).Peripheral nerve injury classification: Classification of peripheral nerve injury assists in prognosis and determination of treatment strategy. Classification of nerve injury was described by Seddon in 1943 and by Sunderland in 1951.Eudemus (physician): Eudemus () was the name of several Greek physicians, whom it is difficult to distinguish with certainty:Calcium signaling: Calcium ions are important for cellular signalling, as once they enter the cytosol of the cytoplasm they exert allosteric regulatory effects on many enzymes and proteins. Calcium can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.Congenital estrogen deficiency: Congenital estrogen deficiency is a genetic condition by which the body is unable to produce or use estrogens.North American Menopause SocietyList of minerals (complete): Mineralogy is an active science in which minerals are discovered or recognised on a regular basis. Use of old mineral names is also discontinued, for example when a name is no longer considered valid.Vesselplasty: Vesselplasty is a surgical alternative in the treatment of vertebral compression fractures (VCFs). It is an image-guided procedure that requires conscious sedations and either general or local anesthesia.Cancer screeningOdanacatibBiomarkers of aging: Biomarkers of aging are biomarkers that better predict functional capacity at a later age than chronological age. Stated another way, biomarkers of aging would give the true "biological age", which may be different from the chronological age.Clay-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.Age adjustment: In epidemiology and demography, age adjustment, also called age standardization, is a technique used to allow populations to be compared when the age profiles of the populations are quite different.Hormone replacement therapy (menopause)Ergogenic use of anabolic steroidsBisphosphonate-associated osteonecrosis of the jaw: Bisphosphonate-associated osteonecrosis of the jaw (often abbreviated as BON, BONJ, or BON of the jaw), also called bisphosphonate-related osteonecrosis of the jaw (BRONJ) (pronounced ) or bisphosphonate-induced osteonecrosis of the jaw (BIONJ), is osteonecrosis of the jaw in a person with a history of bisphosphonate use who undergoes subsequent dental surgery. It may lead to surgical complication in the form of impaired wound healing following oral and maxillofacial surgery, periodontal surgery, or endodontic therapy.BMC Endocrine Disorders: BMC Endocrine Disorders is an open access peer-reviewed scientific journal publishing original research articles in all aspects of the prevention, diagnosis and management of endocrine disorders, as well as related molecular genetics, pathophysiology, and epidemiology.References ==Historadiography: Historadiography is a technique formerly utilized in the fields of histology and cellular biology to provide semiquantitative information regarding the density of a tissue sample. It is usually synonymous with microradiography.Benzo(c)thiopheneHip resurfacing: 155px|right|thumb|The BHRHypovitaminosis DFemoral fractureGlobal Risks Report: The Global Risks Report is an annual study published by the World Economic Forum ahead of the Forum’s Annual Meeting in Davos, Switzerland. Based on the work of the Global Risk Network, the report describes changes occurring in the global risks landscape from year to year and identifies the global risks that could play a critical role in the upcoming year.X-ray microtomography: X-ray microtomography, like tomography and x-ray computed tomography, uses x-rays to create cross-sections of a physical object that can be used to recreate a virtual model (3D model) without destroying the original object. The prefix micro- (symbol: µ) is used to indicate that the pixel sizes of the cross-sections are in the micrometre range.OsteocyteDietary Supplements (database): The PubMed Dietary Supplement Subset (PMDSS) is a joint project between the National Institutes of Health (NIH) National Library of Medicine (NLM) and the NIH Office of Dietary Supplements (ODS). PMDSS is designed to help people search for academic journal articles related to dietary supplement literature.ClomifeneCervical 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.Closed-ended question: A closed-ended question is a question format that limits respondents with a list of answer choices from which they must choose to answer the question.Dillman D.
