[Idiopathic scoliosis in the sagittal plane].

Experimental investigations in animals allow seeing the primary lesion of idiopathic scoliosis in it's lordotic tendency. Modified x-rays in sagittal plane show the lordsification more distinct than conventional lateral views. Lordosification of the scoliotic spine is linked with restricted anteflexion. The disturbance of bending forward is to measure in x-rays. The incidence of disturbed anteflexion is found significant greater in patients than in controls. The contracture of Mm. spinales explains this feature and also the deficit of growth in posterior vertebral column suggested at neuromuscular imbalance. There are conclusions for an early treatment and providence.
