Structural scoliosis
Marfan syndrome (an inherited connective tissue disorder); other connective tissue disorders; neuromuscular diseases (such as cerebral palsy, poliomyelitis, or muscular dystrophy); birth defects (such as hemivertebra, in which one side of a vertebra fails to form normally before birth); injury; certain infections of the spine; tumors (such as those caused by neurofibromatosis, an hereditary disease associated with benign tumors on the spinal column); metabolic (biochemical) diseases; or some arthritic diseases.
Structural scoliosis is different than nonstructural (functional) scoliosis in which the spine appears to have a lateral curve (scoliosis) but it is structurally normal.
