OverviewWhat is ulnar nerve entrapment?Ulnar nerve entrapment is the most common ulnar nerve problem. Ulnar nerve entrapment occurs when something puts pressure on your ulnar nerve in your elbow or wrist. Nerve entrapment is a type of nerve compression syndrome. Show
Compression (a pinched nerve) may lead to inflammation causing nerve (neuropathic) pain and neuropathy (nerve damage). In some cases, this may affect your grip strength, making it difficult for you to grasp items. What is the ulnar nerve?Your ulnar nerve is a single nerve in a network known as the peripheral nervous system, which carries information to and from your brain by route of your spinal cord. Your ulnar nerve helps you bend and straighten your pinky and ring fingers so you can grasp items. The nerve also sends sensory information about touch, pain and temperature. If you bump your ulnar nerve in your elbow, you may experience a tingling “funny bone” sensation. Each arm has an ulnar nerve. What are the types of ulnar nerve entrapment?Ulnar nerve entrapment can occur at your elbow or wrist. Types include:
How common is ulnar nerve entrapment?Cubital tunnel syndrome is the second-most common peripheral neuropathy that affects your upper limbs. (Carpal tunnel syndrome, a pinched median nerve in your wrist, is the most common.) Guyon’s canal syndrome is rare. Symptoms and CausesWhat causes ulnar nerve entrapment?Activities that stretch your ulnar nerve at your elbow, or put a lot of pressure on your elbow, can lead to cubital tunnel syndrome. Sleeping with your elbows bent for long periods can cause or worsen symptoms of ulnar nerve entrapment. Ganglion cysts are noncancerous fluid-filled sacs that form near your wrist joint. These cysts cause up to 40% of Guyon’s canal syndrome. Another 45% of Guyon’s canal syndrome diagnoses occur for no apparent reason (idiopathic). Less commonly, cysts can also cause pressure on the ulnar nerve within your elbow. Other causes of ulnar nerve entrapment and damage include:
What are the risk factors for ulnar nerve entrapment?Ulnar nerve entrapment affects more men than women. People who do jobs or activities that require a lot of elbow or wrist pressure or stretching are most at risk, such as:
What are the symptoms of ulnar nerve entrapment and damage?Signs come on gradually and may come and go. Symptoms may get worse at night or when you do activities that stretch or put pressure on your elbow or wrist. Symptoms of ulnar nerve entrapment and damage include:
Diagnosis and TestsWhat physical exams can diagnose ulnar nerve entrapment?Your healthcare provider may perform several tests during your physical exam to evaluate your symptoms. These tests seem simple, but they help your healthcare provider assess finger and hand strength. They include:
What diagnostic tests can detect ulnar nerve entrapment?These tests can confirm or rule out ulnar nerve entrapment:
Management and TreatmentWhat are nonsurgical treatments for ulnar nerve entrapment?Nonsurgical treatments for ulnar nerve entrapment include:
What are surgical treatments for ulnar nerve entrapment?If nonsurgical treatments don’t help, you may need surgery. Depending on the cause of the nerve entrapment, surgery can:
PreventionHow can I prevent ulnar nerve entrapment?These steps can lower your risk of developing ulnar nerve entrapment, or ease symptoms:
Outlook / PrognosisWhat are the complications of ulnar nerve entrapment?Ulnar nerve entrapment in your elbow or wrist that’s severe can cause muscle loss in your hand. This damage may be permanent in some cases, which is why it’s important to see your healthcare provider early about symptoms. What’s the prognosis for people with ulnar nerve entrapments?About half of all people with ulnar nerve entrapment get symptom relief through nonsurgical means. When needed, surgery may eliminate nerve pain and other symptoms. But for about 1 in 8 people with cubital tunnel syndrome, symptoms may return if the procedure doesn’t fully treat the underlying cause. There’s also a risk of surgical damage to your median nerve, ulnar artery or ligaments in your elbow or wrist.

A note from Cleveland Clinic Ulnar nerve entrapment occurs when something irritates or puts pressure on your ulnar nerve that runs down your arm. Cubital tunnel syndrome affects your ulnar nerve in your elbow. It’s the most common type of ulnar nerve entrapment. Guyon’s canal syndrome, which affects the nerve in your wrist, is a rare peripheral neuropathy. Talk to your healthcare provider if you experience numbness, pain or tingling in your hands or fingers. You can take steps to prevent nerve damage. How do I get rid of numbness in my pinky and ring finger?How is finger numbness treated? Your doctor may recommend over-the-counter (OTC) medication to reduce inflammation. Examples include nonsteroidal anti-inflammatory drugs, such as ibuprofen. Another option is wearing a brace or splint.
Is ulnar nerve entrapment serious?Ulnar nerve entrapment can cause pain, numbness and tingling in the forearm and the fourth and fifth fingers. In severe cases, ulnar nerve entrapment can cause weakness in the hand and loss of muscle mass.
How do you fix ulnar nerve entrapment?Home remedies. icing the affected area for 10 to 15 minutes.. applying topical creams, such as menthol.. stopping activities that cause pain.. taking regular breaks when doing repetitive tasks.. wearing a splint or brace.. using relaxation exercises.. keeping the affected area warm.. elevating the affected area.. What does it mean when your fingers go numb on your right hand?Hand numbness can be caused by damage, irritation, or compression of one of the nerves or a branch of one of the nerves in your arm and wrist. Diseases affecting the peripheral nerves, such as diabetes, also can cause numbness, although with diabetes, similar symptoms usually occur first in your feet.
