From 1987 to 1992, eighty-four elbows of seventy-six patients with cubital tunnel syndrome who had surgical intervention were reviewed. Sixty-two elbows were from male patients and twenty-two were from female patients. In fifty-three elbows the right side was involved, the left side in thirty-one elbows and in eight cases both sides were affected. The average period from the onset of symptoms to the time of operation was two years and five months (range; one month to twenty years). Pre-operatively patients were graded into three groups according to symptoms and clinical examination as mild, moderate and severe into which there were 11, 63 and 10 cases respectively.
In all cases, subcutaneous translocation of the ulnar nerve was performed along with a local fat flap. The follow-up period ranged from one year to six years and four months. During follow-up patients were evaluted according to Ikuta's criteria. There were 20 excellent, 56 good and 8 fair with no poor results, which was very satisfactory. These results led us to conclude that subcutaneous translocation of the ulnar nerve with a local fat flap is an effective method for treating cubital tunnel syndrome caused by vorious mechanisms due to its ability to produce a wide visual field allowing the ulnar nerve to be observed in detail.
