Introduction

Cubital tunnel syndrome occurs when the ulnar nerve, commonly known as the “funny bone” nerve, becomes compressed at the inside of the elbow. This nerve controls sensation in part of the hand and helps with fine motor movements. When it becomes irritated or pinched, symptoms can affect daily activities such as gripping, typing, writing, or even sleeping comfortably. Early diagnosis and treatment can help prevent long-term nerve damage and improve overall function.

What is the Cubital Tunnel?

The cubital tunnel is a narrow space on the inner side of the elbow where the ulnar nerve travels from the upper arm into the forearm. The nerve passes through this tight channel beneath muscle, bone, and soft tissue. Because the space is small, the nerve is vulnerable to pressure or stretching, especially when the elbow is bent for long periods.

How Do I Know if I Have Cubital Tunnel Syndrome?

Common symptoms include:

Numbness or tingling in the ring and small fingers
Hand weakness or difficulty gripping objects
Pain or aching along the inside of the elbow
Symptoms that worsen when the elbow is bent, such as while driving, holding a phone, or sleeping
A feeling that the hand “falls asleep” frequently, especially in the ring and pinky fingers

In more advanced cases, the muscles in the hand may weaken or shrink. A physical exam and nerve tests can help confirm the diagnosis.

Treatments for Cubital Tunnel Syndrome

Most patients improve with non-surgical approaches, such as:

Activity modification to avoid prolonged elbow bending
Elbow padding to prevent leaning on the nerve
Nighttime bracing to keep the elbow in a straighter position
Anti-inflammatory medications to reduce irritation
Nerve-gliding exercises guided by a therapist to improve mobility

If symptoms continue or nerve damage is progressing, surgery may be recommended.

Do I Need Surgery?

Surgery may be advised when symptoms are severe, long-lasting, or not improving with conservative treatment. Surgical options include relieving pressure on the nerve or moving it to a new position where it is less likely to be compressed. The goal is to prevent further damage and improve hand and arm function.

Recovery and Rehabilitation

Recovery depends on the severity of the nerve irritation and whether surgery is performed. Many people notice improvement within weeks of starting conservative treatment. After surgery, recovery may involve a short period of rest followed by therapy to restore movement and strength. The orthopedic specialists at Premier Podiatry and Orthopedics will guide your rehabilitation and tailor your recovery plan so you can safely regain comfort, nerve function, and confidence in your daily activities.
