Endoscopic Cubital Tunnel Release in Leprosy Neuritis of the Ulnar Nerve

Objectives  To better characterize the role of endoscopic cubital tunnel release in leprosy neuritis and determine whether there is an improvement in pain, sensitivity, and strength with the use of this minimally invasive technique. Methods  A total of 44 endoscopic procedures for ulnar nerve decompression at the elbow were performed in patients who were previously diagnosed with leprosy neuritis. The inclusion criteria were surgical indication for ulnar nerve release and clinical treatment failure for 4 weeks in patients with cubital tunnel syndrome who had their ulnar nerve function, whether motor or sensitive, deteriorated progressively despite the treatment with prednisone 1 mg/kg/day and physiotherapy. For endoscopic release, the CTS Relief Kit (Linvatec. Largo, FL, USA) and a standard 4mm 30° arthroscope were used. Results  The study included 39 patients, 29 (74.4%) males and 10 (25.6%) females. The age of the patients ranged from 12 to 64 years (33 ± 14.97). Five patients underwent bilateral release. The release demonstrated a statistically significant improvement in pain ( p 0.002), in sensitivity ( p  < 0.001), and in strength ( p  < 0.001). The best results were obtained when ulnar release was performed less than 6 months after surgery indication. None of the procedures were converted from endoscopic to open. No major complications (infection, vascular injury, and nervous injury) were reported. One patient had ulnar nerve subluxation. Conclusion  The endoscopic release of the ulnar nerve at the elbow in leprosy neuritis entails true and safe benefits for the patient, such as improvement in pain, sensitivity and strength.
