Cubital Tunnel Syndrome

What is Cubital Tunnel Syndrome and what causes it?

The cubital tunnel is the passageway between the prominence of bone on the inner side of the elbow which the ulnar nerve passes, commonly called the “funny bone”. At this site, the ulnar nerve lies directly next to the bone and when there is an increase in pressure, cubital tunnel syndrome can occur as a result.

Causes of Cubital Tunnel

• Chronic compression to this area, such as resting on the elbow, may produce swelling, irritating the nerve. 
• Chronic stretching of the nerve may occur when static postures are maintained for extended periods e.g. sleeping with a bent elbow or whilst holding a phone to the ear. 
• Fractures of the elbow may cause a deformity, which stretches the nerve or narrows the tunnel. 
• Osteoarthritis, Rheumatoid Arthritis or swelling of the joint may narrow the tunnel. 
• Tumors such as ganglion cysts may compress the nerve. 

Signs and Symptoms

• Numbness in the ring and little finger.
• Pain on the inside of the elbow and forearm.
• Hand weakness with gripping.
• Generalised fatigue.
• In its advanced form, muscle wasting and hand contractures can occur.
