The carpal tunnel syndrome. A retrospective study of 400 operated patients

Carpal tunnel syndrome is a common cause of pain, often combined with hypaesthesia in the median distribution of the hand and atrophy of the thenar. We describe pre-, per-, and post-operative findings in 400 patients. Venous stasis is a good diagnostic method in establishing the syndrome. Operative treatment generally gives freedom from pain and normalization of sensibility.
