Carpal tunnel syndrome is a condition caused by pressure on the median nerve at the wrist joint. The carpal tunnel is a narrow passageway, on the palm side of the hand, surrounded by the wrist bones and ligaments. The median nerve runs along this narrow passageway, and compression of this nerve can cause numbness, tingling, and weakness in the hand and arm. A person’s wrist anatomy, and amount of repetitive hand motions may contribute to carpal tunnel syndrome. The median nerve runs from the forearm to the hand. It provides sensation to the palm side of the thumb and fingers and sends nerve signals to move the muscles around the base of the thumb. Several studies have evaluated an association between computer use and carpal tunnel syndrome.
The Most Common Signs & Symptoms of Carpal Tunnel Syndrome
- Numbness or tingling in the fingers or hand, usually the thumb and index, and middle finger are affected
- Sensations that travel from the wrist up the arm.
- Weakness in the hand causing difficulty holding objects
Risk Factors For Developing Carpal Tunnel Syndrome
- Wrist Fracture
- Wrist dislocation
- Wrist arthritis
- Anatomically smaller carpal tunnel that may compress the median nerve
- Sex. Carpal tunnel syndrome is generally more common in women.
- Nerve-damaging conditions such as diabetes
- Inflammatory conditions such as rheumatoid arthritis
- Medications such as anastrozole
- Obesity
- Body fluid retention especially during pregnancy and menopause
- Thyroid disorders, kidney failure and lymphedema
- Working with tools that require prolonged or repetitive flexing of the wrist
