[Traumatic dislocations of the hip in children under 6. Apropos of 10 cases]. / Luxations traumatiques de la hanche de l'enfant de moins de 6 ans: A propos de 10 observations.

ABSTRACT

In a group of 11 traumatic dislocations of the hip, treated between 1962 and 1979, the authors find and study 10 cases of pure dislocation in often mild traumatism, about children between 4 and 5 and half yeard old. They remembre the classic tests the most frequent hit by the boy, frequency of the posterior dislocation, the relative geod pronostic of the hurt in the growth, at this age. In front of theses particular facts of happening, they look for predisposing bone-factors by anamnestic investigations, a coxometric study of the hip, and for 5 children, a tomodensitometric investigation. They cannot have a definitive conclusion, but the results seem to show an association of predisposing articular defects which they go to the dislocation. That would be explain the great frequency of pure dislocations and the rarety of the cephalic necrosis.
