Recently we have few chance to see the older child with untreated CDH owing to the progress of management for CDH in new-born baby or in infant. However incidence of the secondary O A. that occurs following dislocation or subluxation seems to be relatively increasing.
In our clinic we performed the Chiari's transverse pelvic osteotomy for 14 cases of subluxation with acetabular hypoplasia in these 3 years. Now we report the result of the operation with some discussions, though period of follow-up study is short.
