Carpal Tunnel Syndrome Treatment & Surgery

What is Carpal Tunnel Syndrome?

Carpal Tunnel Syndrome (CTS) is a common condition that affects the hand and wrist, caused by compression of the median nerve as it travels through the carpal tunnel, a narrow passageway in the wrist. This nerve is responsible for providing sensation to the thumb, index, middle, and part of the ring finger, as well as controlling some of the muscles at the base of the thumb. When the median nerve is compressed, it can lead to symptoms such as numbness, tingling, pain, and weakness in the hand and fingers.

What Causes Carpal Tunnel Syndrome?

Carpal Tunnel Syndrome can result from various factors, including:

• Repetitive Hand Movements: Repetitive tasks that involve flexing the wrist, such as typing, using a mouse, or assembly line work, can cause swelling and inflammation in the wrist, leading to compression of the median nerve.
• Medical Conditions: Conditions such as diabetes, rheumatoid arthritis, thyroid disorders, and obesity can increase the risk of developing CTS by causing swelling or changes in the tissues around the carpal tunnel.
• Wrist Injuries: Fractures, sprains, or other injuries to the wrist can lead to swelling and compression of the median nerve.
• Genetics: Some individuals may have a naturally smaller carpal tunnel, making them more prone to developing CTS.
• Pregnancy: Hormonal changes during pregnancy can cause swelling in the wrist, which may compress the median nerve and lead to temporary CTS symptoms.

Signs and Symptoms of Carpal Tunnel Syndrome

The symptoms of Carpal Tunnel Syndrome can vary in intensity and may worsen over time. Common signs and symptoms include:

• Numbness or Tingling: A sensation of numbness or tingling in the thumb, index, middle, and ring fingers, often described as a “pins and needles” feeling.
• Pain: Pain in the hand, wrist, or forearm, which may radiate up the arm and worsen at night or with repetitive use.
• Weakness: Weakness in the hand, making it difficult to grasp objects, hold onto items, or perform fine motor tasks.
• Fingers “Falling Asleep”: A sensation that the fingers have “fallen asleep,” particularly during activities that involve bending the wrist or holding objects for extended periods.

Diagnosis of Carpal Tunnel Syndrome

To diagnose Carpal Tunnel Syndrome, a healthcare provider will perform a thorough physical examination, assessing the hand and wrist for signs of numbness, tingling, weakness, and pain. They may conduct specific tests, such as the Tinel’s sign or Phalen’s maneuver, to evaluate the presence of CTS. In some cases, nerve conduction studies or electromyography (EMG) may be used to assess the function of the median nerve and confirm the diagnosis.

Treatment for Carpal Tunnel Syndrome

Treatment for Carpal Tunnel Syndrome focuses on relieving symptoms, reducing nerve compression, and preventing further damage. Options include:

• Rest and Activity Modification: Avoiding activities that exacerbate symptoms and allowing the wrist to rest can help reduce inflammation and relieve pressure on the median nerve.
• Wrist Splinting: Wearing a wrist splint at night or during activities can help keep the wrist in a neutral position, reducing nerve compression and alleviating symptoms.
• Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to help manage pain and reduce inflammation. In some cases, corticosteroid injections may be recommended to provide temporary relief from symptoms.
• Physical Therapy: A structured rehabilitation program focusing on stretching and strengthening exercises for the hand and wrist can help improve flexibility and reduce pressure on the median nerve.
• Surgery: In severe cases where conservative treatments are ineffective, surgical intervention may be necessary. Carpal tunnel release surgery involves cutting the ligament that forms the roof of the carpal tunnel, relieving pressure on the median nerve.
