The treatment of Sudeck's atrophy in the upper limb by sympathetic blockade.

The incidence of Sudeck's atrophy as a sequel to injury in the upper limb has been estimated in relation to casualty attendances in a 3-year period. Seventeen patients were treated at varying intervals after the onset of the condition either by stellate ganglion block or by regional intravenous guanethidine. The results are compared and the advantages of each method are discussed.
