Carpal tunnel syndrome
Definition
also called median nerve compression, is a condition that causes numbness, tingling, or weakness in your hand.
Symptoms
Weakness in your hand and trouble holding things
Shock-like feelings that move into your fingers
Tingling that moves up into your arm
numbness in your palm and thumb or your index and middle fingers
Diagnostic studies
Imaging tests. X-rays, ultrasounds, or MRI exams
Electromyogram. Your doctor puts a thin electrode into a muscle to measure its electrical activity.
Nerve conduction studies.
Risk factors
Have a family member with small carpal tunnels
Fracture or dislocate your wrist
Have a job in which you make the same motions with your arm, hand, or wrist over and over, such as an assembly line worker, sewer or knitter, baker, cashier, hairstylist, or musician
Being a woman because they have smaller carpal tunnels.
Complications
the symptoms can last a long time and get worse.
Health education
Keep your wrists straight.
Use a splint or brace that helps keep your wrist in a neutral position.
Avoid flexing and extending your wrists over and over again.
Keep your hands warm
Put your hands and wrists in the right position while you work.
Take breaks whenever you can.
Pathophysiology
It happens because of pressure on your median nerve, which runs the length of your arm, goes through a passage in your wrist called the carpal tunnel, and ends in your hand. The median controls the movement and feeling of your thumb and the movement of all your fingers except your pinky.
