To the Editor.—In reply to Dr. Rapkin's comments, there is no question that in the majority of cases an unstable hip will become quite stable in just a short time. This was easily demonstrated by Mr. Barlow's work in 1962. There are, unfortunately, two problems that continue to bother us: (1) the uncertainty as to which of these hips will become stable on their own, and (2) the occurrence of congenital subluxation of the hip, or acetabular dysplasia. It would be tragic to neglect early treatment of a congenitally subluxed hip simply because it is indistinguishable from a "self-limited condition." It is for this reason that we feel that the treatment, indeed minimal and without complications, should not be withheld from any child with an unstable hip. Six weeks of treatment is a small price to pay for a normal hip.
