[Aetiopathogenesis of scoliosis, hip dysplasia and torticollis in infancy (author's transl)].

The special risk of the newborn to acquire, skeletal deformities is based on the increased plasticity, intensity of growth and extrapyramidal activity of reflexes which influence each other. These 3 factors may lead to structural growth- and weight bearing deformities in the presence of shrinking contractures and a unilateral oblique habitual position of the trunk. Considering the "Seventh Syndrome" the dual pathogenesis of scoliosis in infancy is discussed from our present point of view (including scoliosis due to oblique body position - moulded baby syndrome - and its deterioration as against true idiopathic infantile or advanced juvenile scoliosis respectively. Similarly is discussed the relation of hip dysplasia due to oblique habitual trunk position in regard to hip dysplasia in connection with CDH as well as the habitual oblique position of the head as against true muscular torticollis.
