Cubital tunnel syndrome – common signs and symptoms

Cubital tunnel syndrome occurs when the ulnar nerve, which passes through the cubital tunnel on the inside of your elbow, becomes irritated, inflamed and at times swollen.

Common symptoms of cubital tunnel syndrome include:

• Aching on the inside of the elbow, that sometimes extends into the forearm and hand
• Tingling/numbness, particularly the ring and/or little fingers
• Weak grip
• Clumsiness of the hand due to muscle weakness, such as when typing or playing an instrument

What causes cubital tunnel syndrome?

• It can occur if you have your elbow bent for a period (such as at night) or if you lean on your elbow for a prolonged period of time. It may also be the result of repetitive lifting/pulling
• Previous elbow trauma, such as a fracture or dislocation
• Arthritis around the elbow
• Often the cause is not known

How is cubital tunnel syndrome diagnosed?

• Your specialist will take a full history and perform a clinical examination
• You may be referred for nerve conduction studies to aid in making a diagnosis. These tests assess how well the ulnar nerve is working and to see where the compression is. The tests can also assess the extent of any muscle damage
• You may need X-rays to assess the bones in your elbow

How can cubital tunnel syndrome be treated?

• Non-surgical treatments may be recommended to treat cubital tunnel syndrome.
• Anti-inflammatories such as ibuprofen can help with the symptoms in the initial stages
• It may also help to avoid leaning on the elbow and to avoid bending it. A splint or the use of a rolled up towel around the elbow at night may help. This will help to keep your elbow in a straighter position, therefore alleviating any unnecessary pressure on the ulnar nerve
• Your consultant may also be able to suggest some exercises, known as nerve gliding exercises
• If your symptoms persist and/or worsen, you may need surgery called ‘cubital tunnel release’ to take the pressure off your ulnar nerve

Cubital tunnel release

• The procedure takes approximately 30-45 minutes
• An incision is made on the inside of your elbow and the ligament roof of the tunnel is cut, to release the compression on the nerve
• This surgery can be performed either under local or general anaesthetic. Your surgeon will discuss the best option for you prior to the procedure. After surgery, usually you are able to go home the same day
• Your surgeon will have a discussion with you about the benefits and risks of surgery with you prior to your surgery
• There will be bulky elbow dressing in place for a few days, which is then reduced to a smaller dressing for approximately another ten days. Your surgeon will talk to you about the usual return to activities such as driving, household tasks aswell as work duties with you prior to your surgery
• Generally, nerve recovery can take a number of months to be noticeable. If there is evidence of muscle wasting prior to surgery, it may well be that symptoms may continue despite surgery
• Your surgeon will discuss with you the expected outcome following this type of nerve decompression surgery
