Carpal Tunnel Syndrome: A Comprehensive Guide

Carpal tunnel is one of the most common nerve-related conditions affecting the hand and wrist. It can interfere with everyday activities like typing, gripping objects, or sleeping comfortably. At Southern California Orthopedic Institute (SCOI), our board-certified hand specialists offer advanced hand care to help patients relieve their pain, restore function, and avoid long-term nerve damage.

Carpal tunnel syndrome occurs when the median nerve, which runs from the forearm into the palm, becomes compressed as it passes through the narrow carpal tunnel in the wrist. This tunnel is formed by bones and ligaments, and any swelling or thickening in this area can reduce space and pinch the nerve.

Take a look at this short video that provides an overview of carpal tunnel, its causes and risk factors, symptoms to watch for, and treatment options.

What Causes Carpal Tunnel?

Some of the most common causes of the syndrome include:

• Repetitive hand or wrist use
• Wrist fractures or trauma
• Inflammatory conditions such as rheumatoid arthritis
• Fluid retention during pregnancy
• Medical conditions such as diabetes or thyroid disorders

If left untreated, carpal tunnel can lead to permanent nerve damage, muscle loss in the hand, and numbness in the fingers.

What Are the Symptoms of Carpal Tunnel Syndrome?

Recognizing the signs of carpal tunnel syndrome early can make a significant difference in treatment outcomes. Symptoms usually begin gradually and may come and go at first, especially at night.

Common symptoms may include:

• Numbness or tingling in the thumb, index, middle, and part of the ring finger
• Pain or aching in the wrist, hand, or forearm
• Weak grip or clumsiness (dropping objects)
• Worsening symptoms during activities like typing, holding a phone, or driving
• Achiness that wakes you at night

Diagnosing Carpal Tunnel Syndrome at SCOI

At SCOI, we believe in a precise diagnosis before recommending treatment. Our orthopedic hand specialists perform a thorough evaluation that may include:

• A detailed medical history and symptom discussion
• Physical exam tests (e.g., Tinel’s sign, Phalen’s maneuver)
• Electromyography (EMG) and nerve conduction studies (NCV) to confirm nerve compression
• Diagnostic ultrasound or MRI imaging when needed

It’s important to rule out other conditions that can mimic carpal tunnel syndrome, such as cervical radiculopathy or tendonitis. Accurate diagnosis ensures the most effective care.

Carpal Tunnel Treatment Options

Nonsurgical, Conservative

Mild to moderate cases of carpal tunnel may improve with conservative care. At SCOI, we offer a full spectrum of nonsurgical options, including:

• Wrist splinting: Worn at night to keep the wrist in a neutral position
• Activity modification: Avoiding repetitive or aggravating motions
• Physical therapy: Stretching and strengthening exercises
• Anti-inflammatory medications: To reduce swelling and discomfort
• Corticosteroid injections: Temporarily reduce inflammation around the nerve

These treatments may provide symptom relief, especially if started early. However, if symptoms persist or worsen, surgical treatment may be necessary.

Surgical Treatment Options at SCOI

When symptoms don’t improve with conservative care or nerve tests show significant compression, carpal tunnel release surgery may be the best option. Carpal tunnel release involves cutting the transverse carpal ligament to relieve pressure on the median nerve. SCOI offers two advanced techniques:

Endoscopic Carpal Tunnel Release Surgery

A minimally invasive approach using a small camera and specialized instruments inserted through a small incision. Benefits include:

• Smaller incision and less scarring
• Faster recovery time
• Earlier return to daily activities

Mini-Open Carpal Tunnel Release Surgery

A traditional method using a slightly longer incision for better visibility of the ligament and nerve structures. Ideal for:

• Severe compression
• Patients with scar tissue or complex anatomy
• Those with prior wrist surgeries

Each procedure is performed on an outpatient basis and tailored to your specific condition and goals.

How To Prevent Carpal Tunnel

While not all cases of carpal tunnel are preventable, certain strategies can reduce your risk:

• Take breaks during repetitive hand activities
• Use ergonomic tools and proper wrist positioning
• Stretch your hands and wrists regularly
• Avoid prolonged pressure on the wrists
• Maintain a healthy weight and manage underlying medical conditions

If you begin to notice carpal tunnel syndrome symptoms, early intervention can help reduce the need for surgery.
