What is Cubital Tunnel Syndrome?

Cubital tunnel syndrome occurs when the ulnar nerve, which runs along the inside of the elbow, becomes compressed or irritated. This can cause numbness, tingling, and weakness in the hand, particularly in the ring and small fingers. The condition is similar to carpal tunnel syndrome but affects a different nerve.

What Causes Cubital Tunnel Syndrome?

• Frequent bending of the elbow (e.g., during work, sports, or sleeping)
• Prolonged pressure on the inside of the elbow (e.g., leaning on armrests)
• Previous elbow injuries or arthritis
• Natural narrowing of the cubital tunnel, where the nerve passes

Common Symptoms:

• Numbness and tingling in the ring and small fingers, especially when the elbow is bent
• Weak grip strength and difficulty with fine motor tasks
• Pain on the inside of the elbow
• A sensation of the fingers “falling asleep”
• In severe cases, muscle wasting in the hand

How is it Diagnosed?

Your hand surgeon will evaluate your symptoms, perform a physical exam, and assess nerve function. They may check for tenderness over the nerve, perform a Tinel’s test (tapping over the nerve to reproduce tingling), and assess grip strength. Nerve conduction studies (NCS) and electromyography (EMG) may be ordered to confirm the diagnosis and evaluate nerve function.

Treatment Options:

• Non-Surgical:
  • Activity modification to avoid prolonged elbow flexion or pressure
  • Wearing a padded elbow brace, especially at night
  • Anti-inflammatory medications (NSAIDs) for pain relief
  • Nerve gliding exercises to improve mobility
  • Corticosteroid injections may provide temporary relief
• Surgical:
  • Ulnar Nerve Release: The nerve is decompressed by removing pressure points within the cubital tunnel.
  • Ulnar Nerve Transposition: It may be necessary to move the nerve to a new position to prevent compression when the elbow bends.
  • Medial Epicondylectomy: A portion of the bone is removed to create more space for the nerve.

Recovery and Rehabilitation:

• Mild cases improve with conservative treatment over weeks to months.
• After surgery, most patients regain function with physical therapy and activity modifications.
• Full recovery can take several months, depending on nerve healing.
