Cubital tunnel syndrome is a disease that affects the ulnar nerve where it crosses the inside part of the elbow. The signs are quite similar to the pain that results when you hit your funny bone. When your funny bone is hurt, you hit the ulnar nerve on the inner side of the elbow. At this point the nerve runs through the cubital tunnel. When this area gets irritated because of pressure, it may cause what is known as cubital tunnel syndrome.
What is the Cubital Tunnel?
The ulnar nerve begins at the side of the neck, where the specific nerve roots leave the spine. The nerve roots exit through minor openings amid the vertebrae. These openings are known as neural for amina.
The nerve roots join with each other to form three main nerves that go down to the hand and the ulnar nerve is one of them.
The ulnar nerve passes through the cubital tunnel behind the inner edge of the elbow. Muscle, ligament, and bone form the tunnel. You may feel it by straightening your arm outwards and rubbing the groove on the inner side of the elbow.
The ulnar nerve passes through the cubital tunnel and goes down the forearm into the hand. It supplies sensation to the little finger as well as half the ring finger. It works the muscle through which the thumb is pulled into the hand’s palm and controls the small muscles of the hand.
What Causes Cubital Tunnel Syndrome?
There can be a number of causes of Cubital tunnel syndrome. It may be a result of the manner in which your elbow functions. The ulnar nerve stretches numerous millimeters when the elbow is bent. Over time, the nerve will change or snap over the bonymedial epicondyle, the point on the inside part of the elbow which may lead to irritation.
A big reason is constant bending of the elbow, doing things like lifting, pulling levers or reaching. Continuous direct pressure on the elbow time and time again can cause cubital tunnel syndrome. The nerve can be irritated by leaning on the elbow when you sit at a desk or when you use the elbow to rest when you are driving for long periods of time.
The ulnar nerve can also be hurt from a blow to the cubital tunnel.
Treatment of Cubital Tunnel
Surgery is not always essential for curing the cubital tunnel. Physical therapy and a splint can provide aid.
If non-surgical treatments are not useful, surgery is an option to release the pressure on the ulnar nerve. There are numerous types of surgery for cubital tunnel syndrome such as Medial Epicondylectomy, in-situ release and Ulnar Nerve Transposition.
