Cubital tunnel syndrome is compression of the ulnar nerve at the inside of the elbow, producing tingling and weakness in the ring and small fingers. Symptoms can develop gradually or after a specific injury, so early evaluation matters when function starts to decline.
Mild cubital tunnel syndrome often improves with conservative care: avoiding leaning on the elbow or keeping it bent for long periods, a night splint or elbow pad that keeps the arm straighter during sleep, and nerve gliding exercises. Steroid injections are generally not used for this condition. When symptoms persist, or there is constant numbness or muscle weakness, our specialists offer the surgical options discussed below.
Below, we walk through the anatomy involved, the symptoms and causes we most often see, how we diagnose cubital tunnel syndrome, and the full range of treatment options, from the simplest to the most involved.
