Structural Scoliosis:


This condition is characterized by abnormal curvature, rotation and twisting of the spine. Due to this, one half of the rib cage is pushed forward (creating large gaps between the ribs) and another half is pushed inward (causing compression of the ribs). The shoulder blade juts out causing differences in levels of the shoulders. Structural scoliosis has the following subtypes-

Idiopathic scoliosis : Origin or cause of this type of scoliosis is not known. 8-10 cases of scoliosis are idiopathic in nature.

Neuromuscular scoliosis: It is mainly observed in cases of muscular dystrophy and neurofibromatosis. The abnormal curvature in this condition is an outcome of disorders of the posterior muscles and nerves. 1 out of 10 cases of scoliosis belongs to this category.

Osteopathic scoliosis : It results due to some major bone defect(s).

Congenital scoliosis :This type of scoliosis occurs due to abnormal spine growth of the fetus in the womb. 1 out of 10 cases of this category is reported.
