Scoliosis axis of a person's spine. In the diagnostic sense, it is defined as a spinal curvature of more than 10° to the right or left as the examiner faces the person, i.e. in the coronal plane. Scoliosis has been described as a biomechanical deformity, the progression of which depends on asymmetric forces otherwise known as the Hueter-Volkmann Law. The traditional medical management of scoliosis is complex and is determined by the severity of the curvature and skeletal maturity, which together help predict the likelihood of progression. The conventional options for children and adolescents are: For adults, treatment usually focuses on
Supernumerary body part two or more different populations of genetically distinct cells that originated in different zygotes that have merged; anatomical structures are typically mixed depending on which cells are prevalent in different body parts, for example plants can have two different types of flowers. A mosaic is a genetic anomaly similar in nature and effects to a chimera: genetically different populations of cells within one organism, originated from some propagated mutation of a single cell rather than from outside sources. In Hindu mythology, additional limbs and heads are considered a sign of power. In Greek mythology, Artemis, the goddess of fertility, was
