Cubital tunnel syndrome is a condition that occurs when the ulnar nerve is compressed or stretched as it passes through the cubital tunnel on the inside of the elbow. This can cause pain, numbness, and other symptoms in the hand and forearm.
People often notice cubital tunnel syndrome when they’re sleeping or holding a phone for a long time, which can put the elbow in a bent position. Other causes include:
- Bending the elbows frequently
- Leaning on the elbow
- Injuries to the area
- Arthritis
- Bone spurs
- Previous elbow fractures or dislocations
If left untreated, cubital tunnel syndrome can lead to muscle wasting in the hand, which can make the hand look bony and not function as well. In extreme cases, it can even cause loss of hand function.
Treatment
The most effective treatment for cubital tunnel syndrome is stopping the activity that is causing the problem.
Treatment may include:
- Resting and stopping any activity that aggravates the condition, such as bending the elbow
- A splint or foam elbow brace worn at night (to limit movement and reduce irritation)
- Using an elbow pad (to protect against chronic irritation from hard surfaces)
- Anti-inflammatory medicines (such as ibuprofen or naproxen)
- Nerve gliding exercises
If these treatments don’t work, the healthcare provider may talk to you about surgery.
