Cubital Tunnel Syndrome

Cubital tunnel syndrome occurs when the ulnar nerve—often called the "funny bone" nerve—becomes compressed, stretched, or irritated as it passes through the cubital tunnel on the inside of the elbow.

Symptoms

• Numbness, tingling, or a "falling asleep" sensation in the ring and little fingers.
• Weakened grip strength and difficulty with fine motor coordination.
• Aching pain along the inner elbow and forearm.

Causes

Frequent or prolonged elbow bending, direct pressure on the inner elbow, repetitive motion, or anatomical variations that cause the ulnar nerve to slide out of place.

Risk Factors

• Prior elbow fractures, dislocations, or bone spurs.
• Repetitive occupational or athletic elbow use.
• Underlying conditions such as diabetes or arthritis.

Diagnosis

A specialized physician evaluates symptoms through a physical exam, nerve provocative tests, and, when necessary, electromyography (EMG) or nerve conduction studies.

Treatment

• Non-Surgical: Activity modification, night splinting to keep the elbow straight, anti-inflammatory medications, and targeted physical therapy.
• Surgical: Nerve decompression or anterior transposition for persistent or severe compression.
