Carpal tunnel syndrome is a condition caused by pressure on the median nerve at the wrist. This nerve is responsible for sensation and movement of parts of the hand. The syndrome can cause pain, numbness, tingling and weakness in the hands and fingers.
Causes of this syndrome include anatomical factors, such as a narrow carpal tunnel, wrist lesions, or conditions that increase pressure on the median nerve and tendons in the carpal tunnel, such as edema. Repetitive hand and wrist activities, such as typing or using hand tools, can also contribute to its development.
The diagnosis of carpal tunnel syndrome is often based on symptoms, and can be confirmed by physical tests and examinations such as electromyography (EMG) or nerve conduction. These tests measure the ability of the nerves to send electrical impulses and respond to these stimuli.
Treatment options vary according to the severity of symptoms. Non-surgical treatments may include wearing splints at night, corticosteroid injections to reduce inflammation, and modifications to daily activities to relieve pressure on the nerve. If these methods are not effective, surgery may be required to relieve pressure by cutting the ligament that forms the roof of the carpal tunnel.
Prevention can include ergonomic adjustments, such as adjusting desk height, using an ergonomic keyboard or mouse, and taking regular breaks to stretch hands and wrists. Specific exercises can also help maintain wrist flexibility and strength.
Yes, it is possible for carpal tunnel syndrome to recur, particularly if the necessary modifications to the work environment or lifestyle are not implemented. After surgery, proper rehabilitation is essential to maximize recovery and minimize the chances of recurrence.
Early symptoms of carpal tunnel syndrome often include tingling or numbness in the fingers, particularly the thumb, index and middle fingers. Some people may also feel a burning sensation or weakness in these fingers and palm. These symptoms may initially appear during the night or on waking.
Although medical treatments are recommended for carpal tunnel syndrome, some natural remedies can complement the treatment. These include the use of ice to reduce inflammation, or supplements such as vitamin B6, which has been associated with symptom reduction. However, it is crucial to consult a healthcare professional before embarking on any new therapeutic approach.
Carpal tunnel surgery, also known as carpal tunnel release, is usually performed under local anaesthetic. The procedure involves cutting the ligament that forms the roof of the carpal tunnel to relieve pressure on the median nerve. The procedure can be carried out using traditional or endoscopic techniques, which are less invasive and enable faster recovery.
Recovery time after carpal tunnel surgery can vary. Most patients start using their hand immediately after surgery for light tasks, although full recovery can take from a few weeks to several months. Physiotherapy is often recommended to restore strength and flexibility to the wrist and hand.
Carpal tunnel syndrome can significantly affect quality of life, making it difficult to perform simple daily tasks such as writing, using a telephone, or holding objects. Without appropriate treatment, symptoms can worsen, leading to persistent pain and reduced hand function, affecting work capacity and personal activities.
