In German speaking countries the cubital tunnel syndrome (CUTS) is better known as sulcus nervi ulnaris syndrome. Next to the carpal tunnel syndrome, it is the second most common neuropathic compression disease in the upper limb [1]. Due to the anatomical positioning of the ulnar nerve at the dorsal area of the elbow, it is located in a vulnerable area where it is exposed to stretch and compression forces in the ulnar nerve sulcus.
