Therapy with vitamin B6 with and without surgery for treatment of patients having the idiopathic carpal tunnel syndrome.


Blood samples from four patients at the time of surgery to relieve the compression of the carpal tunnel syndrome, which was diagnosed by clinical and electromyographic evaluation, were differentially assayed to determine the specific activities and the % deficiencies of the erythrocyte glutamic oxaloacetic transaminase (EGOT). The data from these assays revealed that these four patients had a severe deficiency of vitamin B6. These data, in conjunction with previous biochemical and clinical results over five years, underscore the desirability, and even necessity, of testing by the EGOT analysis for the presence of a severe deficiency of vitamin B6 in all such patients before surgery. Treatment with vitamin B6 (pyridoxine) for a minimum period of 12 weeks, depending upon the duration and severity of the symptoms, has been effective without exception. Surgery may relieve compression, but does not correct a deficiency of vitamin B6. Surgery in addition to therapy with vitamin B6 should be reserved for those patients who have had the deficiency for so many years that much tissue damage is irreversible by pyridoxine, and additional relief from pain can be achieved through the surgery.
