Arthroscopic neurolysis of the ulnar nerve at the elbow.

Cubital tunnel syndrome is a frequent form of neuropathy caused by entrapment of the upper limb. Conservative treatment and physical therapy are the treatment of choice for at least 6 months prior to any type of surgery. The surgical techniques proposed for treatment of this syndrome include simple decompression, transposition and neurolysis. It is the purpose of this study to demonstrate the advantages of arthroscopy for neurolysis of the ulnar nerve at the elbow in a specific cohort of patients. The patients were evaluated preoperatively and postoperatively based on subjective (VAS) and objective (Bishop and Dellon) scales. The degree of patient satisfaction on the average was more than 60%. The mean increase in Bishop score was 5 points (minimum 3, maximum 7). Results appeared to be good and stable at 6 and 12-month follow-up evaluation.
