What is Brachioradialis Release?

Brachioradialis release is a surgical procedure used to alleviate compression or entrapment of nerves—most commonly the radial nerve—caused by the brachioradialis muscle in the forearm. In some cases, the muscle itself or associated scar tissue may compress nearby neurovascular structures, leading to pain, numbness, or functional limitations.

At Katranji Hand Center, brachioradialis release is performed using precision microsurgical techniques to restore function and relieve nerve compression.

Causes

This procedure is typically performed in cases where the brachioradialis muscle or surrounding fascia causes:

• Radial nerve entrapment near the elbow

• Chronic overuse or strain (common in athletes or manual laborers)

• Post-traumatic scarring or fibrosis

• Compartment syndrome or forearm tightness

• Failed conservative treatment for lateral forearm or elbow pain

Signs & Symptoms

Symptoms that may indicate the need for brachioradialis release include:

• Pain or tightness in the lateral forearm

• Weak grip or forearm fatigue

• Numbness or tingling along the radial nerve distribution (back of hand, thumb, index finger)

• Worsening symptoms with repetitive forearm movement

• Tenderness over the brachioradialis muscle belly or near its insertion

Diagnosis

At Katranji Hand Center, diagnosis includes:

• Detailed physical examination – including provocative tests and palpation

• Tinel’s sign or nerve tap test at the lateral forearm

• Nerve conduction studies or EMG – to assess radial nerve function

• Ultrasound or MRI – to visualize muscular or fascial compression

We ensure accurate diagnosis to differentiate from other conditions like lateral epicondylitis (“tennis elbow”) or radial tunnel syndrome.

Treatment Options

Non-Surgical Management

• Activity modification

• Splinting or bracing

• Physical therapy

• NSAIDs or corticosteroid injections

If conservative treatment fails after several weeks to months, surgery may be recommended.

Surgical Release

• Performed under regional or general anesthesia

• A small incision is made along the lateral forearm

• The brachioradialis muscle fascia is carefully incised

• Any compressive scar tissue or thickened bands are released

• The radial nerve is inspected to ensure free gliding

Surgical release helps decompress the nerve and restore normal muscle and tendon mechanics.

Postoperative Care

• Mild dressing and splinting for comfort

• Gradual return to movement within 1–2 weeks

• Physical therapy for strengthening and range of motion

• Full recovery typically expected within 6 to 10 weeks

Associated Risks

As with any surgery, potential risks include:

• Nerve irritation or damage (rare with microsurgical technique)

• Scar sensitivity

• Recurrence of tightness or symptoms

• Infection or wound healing issues

Prognosis

With skilled surgical intervention and proper rehabilitation, the prognosis is excellent. Most patients regain full function and resolution of symptoms. At Katranji Hand Center, we focus on minimally invasive techniques and personalized therapy plans to ensure the best possible outcomes.
