Three patients fulfilling criteria for Sudeck’s atrophy (reflex sympathetic dystrophy syndrome–RSDS) are described and etiological, pathogenetic and clinical features of the disease are reviewed. RSDS is associated with a wide variety of precipitating factors, each of whom, often in concomitance with metabolic diseases and psychiatric disturbances, may cause the same clinical syndrome, which continues in a "vicious circle" of feed-back mechanisms, correlated with sympathetic hyperactivity. The symptoms may begin gradually and the disorder progresses in stages lasting from weeks to months. The management has not yet been established. Generally, the earlier the syndrome is recognized, the better the results of treatment will be. Analgesics, salmon calcitonin and physiokinesitherapy are recommended. Psychological support is advisable. In more severe patients sympathetic blockade and surgical sympathectomy may be necessary. The effects of hyperbaric oxygen treatment must still be assessed.
