Intrafascicular decompression in the treatment of causalgia with special reference to the mechanism.

A new concept of the pathogenesis of causalgia is suggested in accordance with experimental and clinical work. Endoneural hypertension secondary to nerve trunk disruption is incriminated and intrafascicular decompression is used as the key therapeutic measure. In 14 patients with causalgia thus treated, all except 1 were cured. No symptomatic recurrence was noted in a 4- to 6-year follow-up study.
