Roentgenographic criteria were utilized and only cases of frank dislocation unassociated with other disorders were included. It was found that in a child less than one year old, premanipulation traction of twenty-one days or more substantially reduces the incidence of avascular necrosis. For the child more than a year old… CONTINUE READING
