[Algodystrophy of the foot].

The foot is one of the most frequent site of the reflex sympathetic dystrophies, and clinical data associate pain and vasomotor disturbances. Hyperfixation as revealed by bone scan appears early but is nonspecific. X-ray data show demineralization that is typically spotty, and sometimes diffuse. Therapeutic management associates drug treatment (calcitonin) and rehabilitation based on specific rules, in particular, that of "no pain". In the case of failure, regional sympathetic blocks are indicated. The etiologies of the reflex sympathetic dystrophies vary, but are dominated by trauma.
