About Carpal Tunnel Release Surgery

Carpal tunnel syndrome occurs when the median nerve in the wrist is compressed, leading to symptoms such as numbness, tingling, pain, and weakness in the hand. This condition can arise from repetitive movements, injuries, or underlying medical conditions. While splints, therapy, and lifestyle adjustments can help manage symptoms, surgery may be necessary for more severe cases.

Symptoms of Carpal Tunnel Syndrome

Common symptoms of carpal tunnel syndrome include:

• Numbness: Tingling or a numb sensation in the thumb, index finger, middle finger, and part of the ring finger.

• Tingling: A “pins and needles” feeling in the hand or fingers, especially during activities or after waking up.

• Pain: Discomfort in the wrist, hand, or forearm, often worsening at night or during specific tasks.

• Weakness: Reduced strength in the hand or fingers, making it difficult to grip or hold objects.

• Swelling: A sensation of fullness in the hand, even without visible swelling.

• Clumsiness: Difficulty with fine motor skills, such as typing or buttoning clothing.

Causes of Carpal Tunnel Syndrome

Carpal tunnel syndrome develops when the median nerve, which runs from the forearm to the palm, becomes compressed in the carpal tunnel—a narrow passageway in the wrist. Common causes include:

• Repetitive Movements: Engaging in activities that strain the wrist, such as typing or using a mouse.

• Injury or Trauma: Wrist injuries, like fractures or sprains, can lead to swelling that compresses the median nerve.

• Medical Conditions: Disorders such as diabetes, rheumatoid arthritis, and thyroid problems can increase inflammation and swelling around the wrist.

• Genetics: Some individuals may have a naturally smaller carpal tunnel, raising the risk of nerve compression.

• Pregnancy: Hormonal changes during pregnancy can lead to fluid retention and swelling, contributing to carpal tunnel syndrome.

Prevention of Carpal Tunnel Syndrome

To help prevent carpal tunnel syndrome, consider the following strategies:

• Take Breaks: Regularly rest your hands and wrists, especially during repetitive tasks.

• Use Proper Ergonomics: Set up your workstation to maintain a neutral wrist position while typing or using a mouse.

• Exercise: Perform wrist and hand stretches and strengthening exercises to enhance flexibility and reduce strain.

• Wear Wrist Supports: Utilize splints or braces as recommended, particularly during wrist-intensive activities.

• Adjust Hand Positions: Avoid excessive bending of the wrists and keep your hands relaxed and straight.

• Maintain a Healthy Weight: Staying active and eating a balanced diet can help reduce the risk of carpal tunnel syndrome.

Procedure of Carpal Tunnel Release Surgery

Treatment for carpal tunnel syndrome may begin with non-surgical methods, including wrist splints, medications, physical therapy, and lifestyle modifications. In severe cases, surgery is required to relieve pressure on the median nerve by cutting the compressing ligament.

Preparation: Before surgery, patients receive instructions on medication management and fasting. They may undergo preoperative assessments, including an electrocardiogram (ECG) and blood tests.

Anesthetic: On the day of surgery, patients receive anesthesia to ensure comfort and pain relief. This may involve regional anesthesia (such as a wrist block) or local anesthesia combined with sedation.

Incision: The surgeon makes a small incision in the wrist or palm to access the transverse carpal ligament, which forms the roof of the carpal tunnel.

Ligament Release: The surgeon carefully divides the transverse carpal ligament to relieve pressure on the median nerve and enlarge the carpal tunnel. This can be done through minimally invasive endoscopic techniques or traditional open surgery.

Closure: After releasing the ligament, the surgeon uses staples or sutures to close the incision and may apply a sterile dressing.

Recovery: Post-surgery, patients are monitored in a recovery room until stable and fully awake. They receive instructions on wound care, pain management, and hand usage restrictions.

Follow-up: Patients typically schedule follow-up appointments to monitor healing and assess surgical outcomes. Hand exercises or physical therapy may be recommended to support rehabilitation and restore hand function and strength.

Additional Remedies

Carpal tunnel release surgery aims to relieve pressure on the median nerve by severing the ligament that forms the roof of the carpal tunnel. Other potential treatments include steroid injections, physical therapy, wrist splinting, and lifestyle changes to minimize repetitive hand motions. Early intervention and proper ergonomic practices are crucial for effectively managing carpal tunnel syndrome.
