The Prevalence of Cubital Tunnel Syndrome A CrossSectional Study in a US Metropolitan Cohort

Cubital tunnel syndrome is a chronic disorder associated with pain, numbness, and weakness in the hand. It is caused by entrapment of the ulnar nerve at the level of the elbow as it passes behind the medial epicondyle of the humerus, and affected individuals frequently have impairment of work and avocational activities. Left untreated, permanent hand disability may occur1. Despite being one of the most common disorders treated by upper-extremity specialists, high-quality epidemiologic data for this condition are lacking and the general population prevalence remains unknown.
