[Sequelae of post-reduction osteochondritis of the hip and their treatment in adults].

In 71 adult patients who had suffered from osteochondritis after reduction of congenital dislocation of the hip, the authors made a comparative study of the natural evolution (22 cases) and of post-operative evolution after conservative surgery (49 cases), after a minimal period of ten years of observation with a follow-up until fifty or sixty years of age. This led the authors to establish a morphological classification in three types. For each, the natural evolution differed, and the authors were thus able to propose indications for conservative surgery according to the age of the patient and the degree of degenerative changes.
