Abstract
Recalcitrant medial epicondylosis (ME) is a chronic tendinopathy affecting the common flexor-pronator tendon origin which causes significant pain and functional limitations. Recalcitrant ME is difficult to manage with non-surgical treatment options. The medial epicondylar sensory nerve (MEsn) is a small sensory nerve that travels within the medial intermuscular septum to innervate the osseous-tendinous structures of the medial epicondyle. In this report, we describe a novel technique for the treatment of recalcitrant ME via radiofrequency ablation (RFA) of the MEsn under ultrasound guidance. The MEsn is localized under ultrasound in the medial distal arm, just proximal to the medial epicondyle. Patients with a positive prognostic block of the MEsn subsequently underwent RFA of the MEsn. We have performed this procedure on two patients who have demonstrated improvement in pain and function for up to nearly one year after the procedure. The relief from pain and improvement in function of these patients warrants further investigation and comparative trials with respect to conventional treatment options, as MEsn RFA may be a viable treatment option for recalcitrant ME.
