Compression syndromes in reflex sympathetic dystrophy.

Over an 8-year period we treated 93 cases of reflex sympathetic dystrophy. The initial treatment consisted of long-acting intramuscular corticosteroids and active exercises. Twenty-two patients who did not respond significantly to this treatment had carpal tunnel syndrome. In addition, five had cubital tunnel syndrome, one had ulnar tunnel syndrome, and one had a herniated disk of the cervical spine. All nerves were decompressed with significant improvement in the patient's condition. Pain was relieved in all except three who had mild pain. Motion of the proximal interphalangeal joint improved from an average of 35 degrees before operation to 76 degrees after operation. Grip strength improved from an average of 4 pounds to 27 pounds.
