Biomechanical explanation of etiology of the so-called idiopathic scoliosis. Two etiopathological groups-important for treatment and neo-prophylaxis

ABSTRACT

This paper gave basic information of the biomechanical explanation of the etiology of the so-called idiopathic scoliosis. In all children with adolescent idiopathic scoliosis [AIS], a real abduction contracture of the right hip was found to be often connected with the flexion and the out-rotation contracture or only limited range of adduction of the right hip in comparison with the left hip. It was stated that children with the real abduction contracture of the right hip constitute the first etiopathological group of the development of scoliosis. It is double S shaped scoliosis. Patients with only a difference in adduction of both hips constitute the second etiopathological group of the development of scoliosis; it is C shaped lumbar or sacro-lumbar or lumbo-thoracic left convex scoliosis. The right hip abduction contracture, structural or functional is connected with the syndrome of contractures which can be already noticed in newborns and babies
