Carpal Tunnel Surgery

Carpal tunnel syndrome is a common condition that affects millions of people worldwide. It can cause pain, numbness, and tingling in the hand and wrist, making everyday activities challenging. While there are various treatments available for carpal tunnel syndrome, carpal tunnel surgery is often recommended when conservative measures fail to provide relief. In this comprehensive guide, we will explore everything you need to know about carpal tunnel surgery, including its types, procedures, recovery, risks, and alternatives.

What Is Carpal Tunnel Syndrome?

Before diving into the details of carpal tunnel surgery, let’s first understand what carpal tunnel syndrome (CTS) is. CTS is a medical condition characterized by compression of the median nerve as it passes through the carpal tunnel—a narrow passageway located on the palm side of your wrist. The carpal tunnel is formed by the carpal bones in your wrist and the transverse carpal ligament.

The median nerve is responsible for providing sensation to the thumb, index finger, middle finger, and half of the ring finger. It also controls the muscles at the base of the thumb. When this nerve gets compressed or irritated due to various reasons, it can lead to a range of uncomfortable symptoms, including:

  • Numbness: Individuals with CTS often experience numbness or tingling in their fingers, particularly at night.
  • Weakness: Weakness in the hand, especially in gripping objects, is a common symptom of CTS.
  • Pain: Many people with CTS complain of aching or shooting pain in the hand and wrist.
  • Burning Sensation: Some individuals describe a burning sensation in the affected area.
  • Difficulty with Fine Motor Skills: Tasks that require precise movements, such as buttoning a shirt or holding a pencil, can become challenging.

Non-Surgical Treatments for Carpal Tunnel Syndrome

Carpal tunnel surgery is usually considered when conservative treatments fail to provide relief from CTS symptoms. Before opting for surgery, healthcare providers typically recommend various non-surgical approaches, which may include:

  1. Wrist Splinting: Wearing a wrist splint at night can help keep the wrist in a neutral position, relieving pressure on the median nerve.
  2. Medications: Over-the-counter pain relievers or anti-inflammatory drugs can help alleviate pain and swelling.
  3. Corticosteroid Injections: A healthcare provider may inject corticosteroids into the carpal tunnel to reduce inflammation and relieve symptoms.
  4. Physical Therapy: Physical therapists can teach you exercises and techniques to strengthen your wrist and improve flexibility.
  5. Activity Modification: Adjusting your activities to reduce repetitive motions and wrist strain can also be beneficial.
  6. Ergonomic Changes: Making changes to your workspace or using ergonomic tools can reduce strain on your wrists during work.
  7. Alternative Therapies: Some people find relief from CTS symptoms through alternative therapies like acupuncture and chiropractic care.

While these non-surgical treatments can be effective for some individuals, they may not provide long-term relief for everyone. In such cases, carpal tunnel surgery may be recommended.

Types of Carpal Tunnel Surgery

Carpal tunnel surgery, also known as carpal tunnel release surgery, aims to relieve pressure on the median nerve by cutting the transverse carpal ligament. There are two main types of carpal tunnel surgery:

  1. Open Carpal Tunnel Surgery: This traditional approach involves making a small incision in the palm of the hand near the base of the wrist. The surgeon then cuts the transverse carpal ligament to release pressure on the median nerve. Open surgery allows for direct visualization of the ligament and nerve.
  2. Endoscopic Carpal Tunnel Surgery: In this minimally invasive procedure, the surgeon makes one or two small incisions in the wrist or palm. A tiny camera called an endoscope is inserted through one of the incisions, allowing the surgeon to see inside the wrist. Specialized instruments are then used to cut the ligament. Endoscopic surgery typically results in smaller scars and a shorter recovery period compared to open surgery.

Your healthcare provider will determine the most suitable surgical approach based on the severity of your condition, your overall health, and other individual factors.

The Carpal Tunnel Surgery Procedure

Open Carpal Tunnel Surgery

If you and your healthcare provider decide that open carpal tunnel surgery is the best option for you, here’s what you can expect during the procedure:

1. Preparation: Before the surgery, you will receive local anesthesia to numb the area. In some cases, a sedative may also be given to help you relax.

2. Incision: The surgeon will make a small incision at the base of your palm, usually about two inches long.

3. Accessing the Carpal Tunnel: The surgeon will carefully dissect the tissues to access the carpal tunnel and the transverse carpal ligament.

4. Cutting the Ligament: Using surgical instruments, the surgeon will cut the transverse carpal ligament. This release of pressure on the median nerve is the primary goal of the surgery.

5. Closing the Incision: After the ligament is cut, the surgeon will close the incision with stitches or surgical staples.

6. Bandaging and Recovery: A bandage or dressing will be applied to the incision site, and your hand may be placed in a splint or soft cast for support.

Endoscopic Carpal Tunnel Surgery

If you opt for endoscopic carpal tunnel surgery, the procedure will be slightly different:

1. Anesthesia: As with open surgery, you will receive local anesthesia to numb the area.

2. Small Incisions: Instead of a single larger incision, the surgeon will make one or two small incisions in your wrist or palm.

3. Inserting the Endoscope: The surgeon will insert an endoscope through one of the incisions to visualize the carpal tunnel.

4. Cutting the Ligament: Specialized instruments are inserted through the other incision to cut the transverse carpal ligament.

5. Closing the Incisions: After the ligament is cut, the surgeon will close the small incisions with stitches or surgical tape.

6. Bandaging and Recovery: Similar to open surgery, your hand may be bandaged and placed in a splint for support.

Both open and endoscopic carpal tunnel surgeries are typically performed as outpatient procedures, meaning you can go home on the same day as the surgery.

Recovery After Carpal Tunnel Surgery

Recovery after carpal tunnel surgery varies from person to person, but here is a general timeline of what you can expect:

  • Immediate Post-Op: After the surgery, you may experience some pain, swelling, and discomfort. Your healthcare provider may prescribe pain medication to manage these symptoms.
  • Stitches or Staples Removal: If stitches or staples were used to close the incision, they are usually removed within 10 to 14 days.
  • Hand and Wrist Mobility: You will be encouraged to start moving your fingers and wrist gently shortly after surgery to prevent stiffness.
  • Return to Normal Activities: The time it takes to return to normal activities varies but is typically within a few weeks. However, strenuous activities should be avoided for a more extended period.
  • Physical Therapy: In some cases, your healthcare provider may recommend physical therapy to help you regain strength and range of
