Overview
This study evaluates the effect of an ultrasound-guided posterior cutaneous nerve of the forearm epicondylar branch block on pain and functional status in patients with lateral epicondylitis. The procedure is performed using ultrasound guidance. Pain and elbow function are assessed before and after the intervention to determine whether this nerve block can improve pain and functional outcomes in patients with lateral epicondylitis.
