Cubital Tunnel Syndrome

Cubital tunnel syndrome occurs when the ulnar nerve becomes compressed at the inside of the elbow. This compression can cause numbness, tingling, and weakness in the hand, particularly in the ring and pinky fingers. Physical therapy focuses on reducing nerve irritation and restoring arm function.

Do you experience pain on the inside of your elbow along with numbness or tingling in your ring and pinky fingers? These may be signs of cubital tunnel syndrome, a condition caused by compression of the ulnar nerve at the elbow.

At Rose Physical Therapy, with locations in Farragut North, Navy Yard, and Friendship Heights in Washington, DC, our experienced physical therapists help individuals manage nerve compression and restore comfortable arm and hand function.

What Is Cubital Tunnel Syndrome?

The cubital tunnel is a narrow passageway located on the inside of the elbow, behind the bony area commonly known as the “funny bone.”

The ulnar nerve travels through this tunnel as it moves from the neck down to the hand. When this nerve becomes compressed or irritated, symptoms of cubital tunnel syndrome can develop.

Because the ulnar nerve supplies sensation and movement to parts of the hand, compression can affect finger sensation and grip strength.

Causes of Cubital Tunnel Syndrome

Several factors can lead to irritation or compression of the ulnar nerve.

Common causes include:

• Elbow injuries such as fractures or dislocations
• Arthritis causing narrowing of the cubital tunnel
• Bone spurs around the elbow joint
• Prolonged pressure on the elbow while leaning on hard surfaces
• Extended periods with the elbow bent, such as during phone use or sleeping
• Repetitive bending and straightening of the elbow during work or sports

These factors can place pressure on the nerve or reduce space within the cubital tunnel.

Symptoms of Cubital Tunnel Syndrome

Symptoms typically involve nerve irritation in the elbow and hand.

Common symptoms include:

• Pain along the inside of the elbow
• Numbness or tingling in the ring and pinky fingers
• Weak grip or pinch strength
• Difficulty with fine motor tasks
• Coordination problems with the affected fingers
• Electric shock–like sensation when bumping the elbow

Symptoms may worsen when the elbow remains bent for extended periods.

How Cubital Tunnel Syndrome Is Diagnosed

Diagnosis often begins with a physical examination.

Your healthcare provider may also recommend additional testing, such as:

Nerve conduction studies (EMG/NCS)
These tests measure how well the ulnar nerve transmits electrical signals.

Imaging tests

• X-rays to evaluate bone structure
• MRI scans to detect structural issues such as arthritis or bone spurs

These tests help identify the severity and location of nerve compression.

Physical Therapy Treatment for Cubital Tunnel Syndrome

At Rose Physical Therapy, treatment focuses on reducing pressure on the ulnar nerve and improving arm mobility.
