Cubital Tunnel Syndrome.

Cubital tunnel syndrome is the most common cause of symptomatic ulnar neuropathy. The unique anatomic course of the ulnar nerve around the elbow makes it particularly vulnerable at a location far from its terminal destination. The natural progression of cubital tunnel syndrome allows patients who have mild symptoms to be adequately treated nonsurgically. Minor changes in activity combined with appropriate splinting may acceptably alleviate symptoms. Surgical intervention is recommended for patients who have more severe symptoms. Current data confirm that in situ ulnar nerve decompression, partial medial epicondylectomy, and anterior transposition result in equal success rates; however, more invasive techniques may increase the risk for complications. If primary surgical intervention fails, revision surgery can provide good results. Modern techniques for revision surgery incorporate the placement of a protective circumferential barrier around the pathologic nerve to mitigate cicatrix formation. Although several attractive options are currently available for the management of cubital tunnel syndrome, further research is necessary to guide treatment.
