Overuse of the elbow or prolonged positioning of the elbow in flexed position can lead to cubital tunnel syndrome. Simply bending the elbow causes stretching of the ulnar nerve and narrows the diameter of the cubital tunnel which can potentially lead to irritation. As a reference, this area is known as the “funny bone”, and a blow to the ulnar nerve here produces a painful, shock-like jolt.Ĭubital Tunnel Syndrome is a result of entrapment, pressure, or irritation of the ulnar nerve at the elbow. As the ulnar nerve passes through this cubital tunnel it is extremely close to the skin’s surface, and prone to trauma. The tunnel is located behind the bony protuberance of the medial epicondyle. The cubital tunnel is an anatomic space formed by the humerus, the medial collateral ligament, and its retinaculum. It also gives motor control to many of the small muscles of the hand responsible for dexterity and some of the larger muscles of the forearm responsible for grip strength.

Its sensory functions include sensation in the pinky finger and one half of the ring finger.
