Perinatal dislocation of the hip — C. D. H. — is influenced by mechanical and hormonal factors. The authors' experiments on rats confirm that persistent knee extension, ovariectomy and administration of progesterone increased the rate of dislocation, whereas division of either iliopsoas or the hamstring muscles or administration of oestrogen had a protective effect. The hormonal changes greatly influenced the collagen and elastin content of the joint capsule.

Key words

Hip Congenital dislocation of the hip 


La luxation congénitale de la hanche (C. D. H.) survient sous l'influence de facteurs mécaniques et hormonaux. L'expérimentation pratiquée par les auteurs sur le rat confirme que l'extension prolongée du genou, l'ovariectomie et l'administration de progestérone augmentent la fréquence des luxations tandis que la section de l'iliopsoas ou des ischiojambiers ainsi que l'administration d'oestrogènes ont un effet protecteur. Les modifications hormonales ont⋅une influence considérable sur la proportion de fibres collagènes et élastiques de la capsule articulaire.
