Cubital tunnel release with endoscopic assistance: Results of a new technique☆☆☆★★★

Abstract 

We evaluated the results of cubital tunnel release with endoscopic assistance. The study included 76 patients (85 elbows); 47 women and 29 men. Nine patients had bilateral procedures. Patients were excluded if they had less than 1 year of follow-up, associated pathology at the elbow to account for the nerve compression, or recurrent cubital tunnel syndrome. Before surgery, cases were categorized by stage of cubital tunnel syndrome according to Dellon's classification: 33 (39%) elbows were classified as mild, 35 (41%) moderate, and 17 (20%) severe. Surgical results were assessed according to a modified Bishop rating system. The mean follow-up period was 32 months (range, 12–52 months). Results were excellent in 42% of the elbows, good in 45%, fair in 11%, and poor in 2%. Recurrence occurred in 3 elbows. There were no serious complications. The results of this study support our recommendation of cubital tunnel release with endoscopic assistance as a safe and reliable technique for the treatment of cubital tunnel syndrome, especially in patients with mild to moderate symptoms.
