Cubital Tunnel syndrome (CTS) can affect anyone. In most cases the cause remains unknown but a number of medical conditions such as pregnancy rheumatoid arthritis, thyroid disease, and wrist injuries can increase the risk of CTS occurrence.If the ulnar nerve, which is passing through a tunnel of the inner side of the elbow joint known as cubital tunnel, is pressed at that location, resulting pressure will initiate appearance of symptoms of CTS.


Typical sensation triggered by pressure on the ulnar nerve can be described as pricking in the little and ring finger and in the inner side of the forearm, which is usually relieved by shaking the arm. Severe CTS cases may cause deterioration of certain muscles in the palm thus affecting position and strength of thumb and little finger.

Clinical procedures carried out during the examination of the patient used for triggering a CTS syndrome are a minute-long Flexing of the elbow or tapping on the nerve in the cubital tunnel. More complex cases may require a nerve conduction study.


CTS treatment may be nonoperative, as in mild cases, and include therapy by painkillers and resting splints. Most patients whose symptoms are harsher will undergo surgery. It is a single day procedure and the surgery itself takes less than half an hour and requires only local anesthesia. Effects of the anesthesia wear off in about six hours and pain control by analgesia should begin before the effects of anesthesia are gone.

Patient is released home soon after operation, and surgery follow-up procedures given by the physician should be followed. It is generally advised to exercise bending and stretching of fingers immediately, to keep the arm elevated (held above the heart level) in order to prevent swelling of the hand and fingers, and to avoid straining of muscles on the treated hand for two to three weeks.

Improvement may be observed within a week and complete recovery after up to three months. Return period to unhampered normal daily activities, such as driving, work and manual labor may vary and physician should be consulted. Putting too much strain on a newly healed wound can cause complications.

Complications after surgery

A minor percentage of treated patients may experience complications. Majority of these complications are comprised of infections, numbness, neuroma and bad reaction of the organism to surgery. More specific complications are unresolved symptoms, which is usually the case if the nerve has been scarred by pressure prior to surgery, numbness at the tip of the elbow and tendency of the nerve to jump out of its position when the elbow is moved.
