n. a sharp posterior angulation of the spine due to localized collapse or wedging of one or more vertebrae. It results in the appearance of a hump on the back (a hunchback deformity). The cause may be a congenital defect, a fracture (which may or may not be pathological), or spinal tuberculosis.
A combination of SCOLIOSIS and KYPHOSIS in which the spine (see SPINAL COLUMN) is abnormally curved sideways and forwards. The condition may be the result of several diseases affecting the spinal muscles and vertebrae, or it may happen during development for no obvious reason. Although braces may reduce the deformity, an operation may be necessary to correct it.... kyphoscoliosis
