The common causes responsible for cubital tunnel syndrome, include:įrequent pressure on the elbow for extended periods due to sitting posture Muscle wasting in the hand and permanent nerve damage, if left untreated. Weakness in hand with diminished grip strengthĭiminished sensation and fine motor control in the hand causing the person to drop objects or have difficulty in handling small objects. These symptoms occur more frequently at night, and with elbow bending or prolonged resting on the elbow. Intermittent numbness, tingling, and pain to the little finger, ring finger, and the inside of the hand. Commonly reported symptoms associated with Cubital Tunnel Syndrome include: Left untreated, Cubital Tunnel Syndrome can lead to permanent nerve damage in the hand. In general, signs and symptoms of Cubital Tunnel Syndrome arise gradually, progressing to the point where the patient seeks medical attention. When the ulnar nerve is compressed or entrapped, the nerve can tear and become inflamed leading to a variety of symptoms, called cubital tunnel syndrome. When the elbow is bent, the ulnar nerve can stretch and catch on the bony bump. The roof of the cubital tunnel is covered with a soft tissue called fascia. The cubital tunnel is a narrow passageway on the inside of the elbow formed by bone, muscle, and ligaments with the ulnar nerve passing through its center. The ulnar nerve travels down the back of the elbow behind the bony bump called the medial epicondyle, and through a passageway called the cubital tunnel. Evans recommends using a headset instead of holding your phone to your ear.Cubital Tunnel Syndrome is a condition characterized by compression of the ulnar nerve in an area of the elbow called the cubital tunnel. Other things to avoid include resting your elbow on armrests, keeping your elbow bent for extended periods of time, leaning on your elbow, or sitting in a low chair while using a computer. Wearing an elbow splint at night will prevent you from bending your elbow while you’re asleep. “Cubital tunnel syndrome is treated by avoiding elbow flexion during activities and while sleeping,” says Dr. ![]() ![]() X-rays may be taken to detect visible causes of compression, such as bone spurs or elbow arthritis. Your doctor will perform a physical exam and may order nerve conduction studies to identify where the nerve is being compressed. If you think that you may have cubital tunnel syndrome, see your doctor. However, cubital tunnel syndrome is a very late occurrence in the course of arthritis, which is uncommon at the elbow. Evans.Ĭubital tunnel syndrome can also be caused by joint damage from arthritis. “ Diabetes is probably the most commonly associated disease,” says Dr. People who have fractured or dislocated their elbow or who have bone spurs or swelling in the elbow are at increased risk of ulnar nerve compression. Bending your elbow repeatedly, sleeping with your elbow bent, or prolonged leaning on your elbow can also cause cubital tunnel syndrome. Ulnar nerve compression can occur in people who hold their elbow bent more than 90 degrees for long periods of time. “Carpal tunnel syndrome involves the median nerve and affects your thumb, index and long finger,” explains Dr. Severe or long-term compression can lead to muscle wasting, which can’t be reversed.ĭon’t confuse cubital tunnel syndrome with the more common nerve entrapment syndrome, carpal tunnel syndrome. More severe cases of ulnar nerve compression can cause weakness of grip and difficulty with finger coordination. Ulnar nerve compression may also cause tingling, numbness, burning or aching in the forearm. The nerve can become compressed at this region because the tunnel is very narrow, and there is little soft tissue to shelter it. Evans, MD, PhD, who specializes in hand, elbow and shoulder problems. “Cubital tunnel syndrome is a condition where your ulnar nerve gets progressively compressed (or has too much pressure on it),” says orthopaedic surgeon Peter J. This nerve passes through an opening at the elbow called the cubital tunnel. It connects to small muscles in the hand that are critical for power grip. ![]() The ulnar nerve, commonly called the “funny bone,” runs from the neck down to the hand and provides sensation to the ring and little fingers.
