Cubital tunnel syndrome
Cubital Tunnel Syndrome is a condition that involves pressure or stretching of the ulnar nerve (also known as the "funny bone" nerve), which can cause numbness or tingling in the ring and small fingers, pain in the forearm, and/or weakness in the hand. The ulnar nerve runs in a groove on the inner side of the elbow.
Causes[edit | edit source]
Cubital Tunnel Syndrome is caused by increased pressure on the ulnar nerve, which can happen for a variety of reasons. The nerve can be compressed at several places along its course, but it is most commonly compressed behind the elbow. This can occur when the elbow is bent for extended periods, such as during sleep or while talking on a mobile phone. Some people are born with an unusually narrow cubital tunnel, which can also cause this condition.
Symptoms[edit | edit source]
Symptoms of Cubital Tunnel Syndrome may include:
- Pain and numbness in the elbow
- Tingling, especially in the ring and little fingers
- Weakness affecting the ring and little fingers
- Decreased ability to pinch the thumb and little finger
- Decreased overall hand grip
- Muscle wasting in the hand
- Deformity of the hand (in severe or long-term cases)
Diagnosis[edit | edit source]
Diagnosis of Cubital Tunnel Syndrome typically involves a physical examination and a medical history. During the physical examination, the doctor may perform a Tinel's sign test, in which the doctor taps over the nerve to see if it produces a tingling sensation in the fingers. Other tests may include an electromyography (EMG) and nerve conduction studies.
Treatment[edit | edit source]
Treatment for Cubital Tunnel Syndrome depends on the severity of the symptoms and the nature of any underlying conditions. Non-surgical treatments may include avoiding activities that cause symptoms, wearing a splint or brace, and physical therapy. If these treatments do not relieve the symptoms, surgery may be necessary to reduce pressure on the nerve.
