The foot in juvenile chronic arthritis

The authors have analysed 100 files of children suffering from JRA treated in Nancy Children's Hospital. JRA is frequent and early in the foot. It is mainly located int the hind foot. Its evolution is pernicious and difficult to assess clinically. Conventional X'Rays show classic signs (often late) of the inflammatory attack. Anomalies of bone growth are early and show persistance of inflammatory process. IRM could give some essential information about location of inflammation.
