[Etiology of diseases of the hip joint in children].

The rentgenometric examination of the hip joint in 165 children with a high degree of reliability of the coxitis syndrome has revealed a displastic nature of the disease in 49,5% of them. It was mainly due to non-correct orientation of the proximal end of the femur. The overstrain of such joint causes its functional incompetence, pain, restricted functioning and lameness. The investigation performed enabled the author to establish the etiology of the disease, to assess the degree of maldevelopment of the hip joint and to find new ways of pathogenetic therapy.
