Prime factors in the etiology of congenital dislocation of the hip and talipes equinovarus in Riyadh

ABSTRACT

This paper reports a prospective controlled study over a period of two years. One hundred thirty-seven patients [79 with congenital dislocation of the hip [CDH] and 58 with talipes equinovarus [TEV] and 144 controls were studied t find out if there is any association between several possible etiologic factors and CDH or TEV deformities in Riyadh. The study demonstrated a strong association between CDH and breech presentation, younger age of the mother, and prematurity, and TEV and low birth weight of the newborn. On the other hand, there was no significant association between TEV and breech presentation or prematurity, and neither CDH nor TEV and disease of pregnancy, consanguinity of parents, parental history of malformation, X-ray exposure, or rubella infection during pregnancy. No single theory can explain the etiology of all idiopathic TEV and CDH. Different causative factors can produce the same deformity. Both mechanical and genetic factors appear to combine in variable digress to cause TEV. In the case of CDH, in uteri conditions appear to play an important role
