What is the carpal tunnel?
The carpal tunnel could be a narrow canal within the wrist. very cheap and sides of the tunnel are shaped by a semi-circle of bones called carpal bones. a powerful tissue, called a ligament, forms the highest of the tunnel. The median nerve and tendons pass through this narrow area. (The tendons are “rope-like” structures that connect muscles within the forearm to bones within the hand.) Tendons enable the fingers and thumb to bend and straighten. Conditions that further narrow the carpal tunnel or cause the tendons that meet up with this tunnel to swell cause carpal tunnel syndrome by compression the median nerve.
What is carpal tunnel syndrome?
The wrist comprises of several small bones collectively known as the carpal bones. The carpal bones are interconnected via strong ligaments and connective tissue known as the flexor retinaculum. Collectively, this arrangement forms a space known as the carpal tunnel .The carpal tunnel contains numerous flexor tendons from the muscles of the forearm allowing them to attach to the wrist and fingers via the carpal tunnel. In addition, a nerve known as the median nerve lies within the carpal tunnel . The median nerve is responsible for supplying some sensation and motor control to the hand.
Occasionally, the carpal tunnel may narrow resulting in compression of the median nerve. When this occurs, the condition is known as carpal tunnel syndrome. Carpal tunnel syndrome normally occurs following damage to the flexor tendons within the carpal tunnel. This results in swelling and inflammation of the tendons, thereby reducing the dimensions of the carpal tunnel, compressing the median nerve.
Damage to the flexor tendons usually occurs due to overuse of the forearm flexors. During contraction of the forearm flexors, tension is placed through the flexor tendons within the carpal tunnel. When this tension is excessive due to too much repetition or high force, damage to the tendons may occur. This is usually due to gradual wear and tear associated with overuse, however, it may also occur traumatically due to a specific incident. Although carpal tunnel syndrome can occur at any age, it is commonly seen in patients greater than 50. Carpal tunnel syndrome is also more common in women
The Most Common Symptons of Carpal Tunnel Syndrome Include :-
- Numbness, tingling, and pain in the hand
- An electric shock-like feeling mostly in the thumb, index, and long fingers
- Strange sensations and pain traveling up the arm toward the shoulder
Symptoms usually begin gradually, without a specific injury. In most people, symptoms are more severe on the thumb side of the hand.
What are the Aims and Benefits of Carpal Tunnel Release Surgery?
- Relief from Neural Compression
- Pain Reduction
- Prevention of Further Deterioration
The chance of obtaining a significant benefit from surgery depends upon a wide variety of factors. Your neurosurgeon will give you an indication of the likelihood of success in your specific case.
