Scoliosis in an identical twin: a case report with literature review

Abstract

Scoliosis is called the lateral angulation of the vertebra more than 10 degrees. Scoliosis is divided into two groups that is congenital and idiopathic scoliosis. Congenital scoliosis was presented in one of the two 14-year-old sisters who were identical twins; while the other developed adolescent idiopathic scoliosis. The sister with congenital scoliosis has hemivertebra in the thoracic third and seventh vertebras, block vertebra in the thoracic 10th-11th vertebras, and fusion the L3-L4 vertebras. The Cobb angle of this sister was 44.4 degrees of thoracic scoliosis. In the other sister, 13.8 degrees lumbar scoliosis was detected. Scoliosis has been shown to occur not only with the genetic background but also due to low birth weight.
