Carpal Tunnel Syndrome: Symptoms, Treatment & When Surgery May Help

Contributing orthopaedic specialist: Nicholas Loafman, DO

Waking up with numb or tingling fingers? Finding it difficult to grip your steering wheel, hold your phone, or complete everyday tasks?

These symptoms are easy to dismiss at first. But when hand discomfort becomes persistent or begins interrupting your sleep, it may be a sign of carpal tunnel syndrome, a common condition affecting the median nerve in the wrist.

At Southwest Michigan Center for Orthopaedics & Sports Medicine (SWM Ortho), our orthopaedic specialists help patients identify the causes of hand and wrist symptoms and understand their treatment options, including carpal tunnel release surgery when appropriate.

What Is Carpal Tunnel Syndrome?

Carpal tunnel syndrome develops when the median nerve becomes compressed as it travels through a narrow passageway in the wrist known as the carpal tunnel.

The median nerve provides sensation to the thumb, index finger, middle finger, and part of the ring finger. It also helps control certain muscles near the base of the thumb.

When pressure on the nerve increases, patients may experience tingling, numbness, discomfort, or weakness that makes ordinary activities more difficult.

Symptoms may develop gradually and can become more persistent over time.

What Are the Common Symptoms of Carpal Tunnel Syndrome?

Carpal tunnel syndrome can affect people differently, but several symptoms are particularly common:

• Numbness or tingling: Often affecting the thumb, index finger, middle finger, and part of the ring finger.

• Nighttime discomfort: Symptoms may wake patients from sleep or lead them to shake their hands to find relief.

• Difficulty gripping objects: Everyday tasks such as opening containers or holding a phone may become more challenging.

• Hand weakness: In more advanced cases, weakness can affect thumb function and the ability to hold objects securely.

• Pain or discomfort: Symptoms may be felt in the wrist and hand and sometimes extend into the forearm.

Because other conditions can cause similar symptoms, an accurate diagnosis is important before beginning treatment.

What Causes Carpal Tunnel Syndrome?

Carpal tunnel syndrome develops when pressure increases around the median nerve at the wrist.

Several factors may contribute to the condition, including wrist anatomy, inflammatory conditions, diabetes, pregnancy-related fluid changes, and other medical or occupational factors.

Repetitive or sustained wrist positions may aggravate symptoms, although carpal tunnel syndrome is not always caused by repetitive activity.

An orthopaedic evaluation can help determine whether the median nerve is involved and identify other possible causes of hand numbness or weakness.

Can Carpal Tunnel Syndrome Be Treated Without Surgery?

Surgery is not always the first treatment option.

Depending on the severity of symptoms and the extent of nerve compression, an orthopaedic specialist may recommend conservative measures such as:

• Wearing a wrist splint, particularly at night

• Modifying activities that aggravate symptoms

• Addressing contributing medical conditions

• Considering corticosteroid injections when appropriate

Treatment begins with understanding the cause and severity of your symptoms. Learn more about the nonsurgical orthopaedic treatment options available at SWM Ortho.

The effectiveness of nonsurgical treatment varies. If symptoms continue, worsen, or involve significant nerve dysfunction, surgical treatment may become an important consideration.

How Does Carpal Tunnel Release Surgery Work?

Carpal tunnel release surgery is designed to reduce pressure on the median nerve.

During the procedure, the surgeon divides the transverse carpal ligament, which forms the roof of the carpal tunnel. Releasing this ligament creates more space for the compressed nerve.

The goal is to prevent continued nerve compression and help reduce symptoms such as numbness, tingling, and weakness.

Carpal tunnel release can be performed through different surgical approaches. Your surgeon will determine which technique is appropriate based on your condition and individual needs.
