[Radiological appearances in Blount's disease]

The radiological appearances in 16 Antilles patients with Blount's disease are described, and a classification is proposed according to the modifications noted during the course of the disease. Six stages can be identified during growth. A decisive stage appears to be that of stage IV when spontaneous epiphysiodesis occurs in the internal part of the epiphysial cartilage. Corrective osteotomy at this stage is always followed by recurrence of the tibia varum. The results of arthrography are defined as well as possible associated pathological affections.
