Radial Tunnel Syndrome

Radial Tunnel Syndrome: Treatment in Palm Beach

Radial tunnel syndrome involves compression of the radial nerve as it passes through the radial tunnel in the outer forearm, just past the elbow. It is frequently confused with tennis elbow because both cause lateral forearm and elbow pain, but the underlying mechanism and treatment approach are fundamentally different.

Accurate differentiation of radial tunnel syndrome from lateral epicondylitis is an area where Dr. Ghattas's nerve expertise provides significant value to patients who have not responded to tennis elbow treatment. If you are suffering from this condition, contact our office today.

What Is Radial Tunnel Syndrome?

The radial nerve divides just past the elbow into the superficial radial nerve and the posterior interosseous nerve (PIN). The PIN passes through the radial tunnel, where it can become compressed at the arcade of Frohse (the leading edge of the supinator muscle), producing lateral forearm pain without the grip weakness typical of PIN palsy.

Signs and Symptoms

• Aching pain in the outer forearm and lateral elbow
• Pain worsening with resisted forearm supination or wrist extension
• Tenderness approximately 4 to 5 centimeters distal to the lateral epicondyle (distinguishes from tennis elbow tenderness directly at the epicondyle)
• No significant grip weakness in most cases
• Symptoms that persist despite appropriate tennis elbow treatment

Common Causes and Risk Factors

• Repetitive forearm rotation activities
• Fibrous bands or anomalous vessels at the radial tunnel
• Direct forearm compression
• Prior radial head fracture or elbow surgery

How It Is Diagnosed

Clinical examination with the specific resistance tests and tenderness location are the primary diagnostic tools. Electrodiagnostic studies are often normal in radial tunnel syndrome. A diagnostic ultrasound-guided injection at the radial tunnel that relieves symptoms confirms the diagnosis.

Conventional Treatment Options

• Activity modification and forearm stretching
• Physical therapy targeting the supinator and radial nerve mobility
• Ultrasound-guided injection at the radial tunnel
• Surgical decompression at the arcade of Frohse for refractory cases

The Palm Beach Regenerative Approach

Dr. Ghattas uses real-time ultrasound guidance to identify and treat the radial nerve compression at the radial tunnel with targeted nerve hydrodissection and platelet injection, addressing the perineural inflammation and freeing the nerve from compressive adhesions.

Ensuring the correct diagnosis before treatment is a hallmark of the Palm Beach Regenerative approach. Treating radial tunnel syndrome as tennis elbow will not provide relief. Request an appointment at our clinic today.

The BioMod Advantage: MLS Robotic Laser Therapy applied to the lateral elbow and proximal forearm reduces inflammation at the radial tunnel and surrounding soft tissues. Xymogen nerve support protocols provide nutritional support for radial nerve recovery from chronic compression.

Like all medical procedures, orthobiologic treatments have potential risks and benefits. Results vary by individual. Not all patients are candidates. Dr. Ghattas will discuss your specific situation, realistic expectations, and all treatment options, including when surgery or other interventions may be more appropriate.
