Commonly known by some as the cubital tunnel syndrome, the syndrome of the flexor carpi ulnaris muscle includes ulnar nerve compression, since it courses not only in its sulcus behind the medial humeral epicondyle, but also between the two heads of the flexor carpi ulnaris muscle. However, Fiendel and Stratford

described ulnar nerve compression in the latter situation as the cubital tunnel syndrome. To avoid confusion, this book will use the more inclusive definition to pinpoint accurately the region in question.
