Title: Carpal Tunnel Syndrome
1Carpal Tunnel Syndrome Carpal tunnel syndrome is
a common disorder that causes pain, numbness,
tingling, and weakness in the hand and wrist. It
occurs when there is a high amount of pressure
within the wrist on a nerve called the median
nerve. This median nerve provides sensation to
the thumb, index, and middle fingers, and half of
the ring finger. The little finger (the pinky)
is typically not affected. This median nerve also
provides strength to few muscles at the base of
the thumb and index finger. Carpal tunnel -
Carpal tunnel is a narrow passage in the wrist.
The bottom and sides of the tunnel are formed by
small semi-circular bones called carpal bones. A
tissue called ligament forms in the top of the
tunnel. The median nerve and tendons pass
through this space. These tendons connect muscles
in the forearm to bones in the hand. These help
the finger and thumb to bend and
straighten. Who is at risk? Women are three
times more possible to have carpal tunnel
syndrome than men. Carpal tunnel syndrome is
mostly diagnosed between the ages of 30 and 60.
Jobs that involve repetitive finger use, mainly
those associated with high force, extreme wrist
motions may develop this disorder. Many factors
contribute to the development of carpal tunnel
syndromes such as high salt intake, sedentary
lifestyle and, obesity. People who work in
professions like Manufacturing, Assembly line
work, Keyboarding occupations, and Construction
work are at greater risk. Causes The carpal
tunnel is a narrow passage in the wrist it is
surrounded by bones and ligaments. Tendons run
through the carpal tunnel and help the fingers
and the median nerve move, which is responsible
for both sensation and movement in the hand,
thumb,
2- index finger, middle finger, and ring finger.
Any condition that causes swelling of the
membranes of the carpal tunnel can lead to the
carpel tunnel syndrome. When the tissues of the
carpal tunnel become swollen, it will cause the
median nerve to be compressed, which is known as
nerve entrapment. - Conditions related to carpal tunnel syndrome are
- Diabetes
- Thyroid dysfunction
- Fluid retention from pregnancy or menopause
- High blood pressure
- Autoimmune disorders such as rheumatoid arthritis
- Fractures or trauma to the wrist
- Wrist fracture or dislocation
- Wrist Deformity
- Tumor in the carpel tunnel
- Older age
- Placing of your wrists while using your keyboard
or mouse - Continuous exposure to vibrations from using
hand-tools or power-tools - playing the piano or typing
- Symptoms
- Symptoms begin slowly, early symptoms occur along
the nerve path because of compression of the
median nerve. Your hand may asleep often and drop
objects.
3Diagnosis
- Your doctor will check your medical history and
examine you. Later tests are performed, that
include- - Tinels sign- In this test, the doctor will tap
over the median nerve at the wrist to check if it
produces a tingling sensation in the fingers. - Wrist flexion test- in this test, the patient
rests his elbow on a table and allows the wrist
to fall forward freely. People with carpal
tunnel syndrome will experience numbness and
tingling in the fingers within 60 seconds. The
severity of the carpal tunnel syndrome is
diagnosed based on how quickly symptoms appear. - X-rays X-rays of the wrist is done if there is
limited wrist motion, or to exclude if any other
causes such as arthritis or fracture. - Electromyography (EMG) This test is conducted to
know the health of the muscles and the nerve
cells that control them. A thin needle electrode
is inserted into specific muscles to evaluate the
electrical activity when muscles contract and
rest this is to find out if there is any muscle
damage. - Nerve conduction study. In this test, two
electrodes are taped to the skin and a small
shock is passed through the median nerve to
check if electrical impulses are slowed in the
carpal tunnel. This method is done to check your
condition and to rule out other conditions.
Treatments for CTS given are
- If the Carpal tunnel syndrome is diagnosed at an
early stage then non-surgical treatments are
given first such as - Avoid continuous movement of your hand
- Wrist splints that hold your hand in a neutral
position - Medication for mild pain and to reduce
inflammation - Treatment of any underlying conditions you may
have, such as diabetes or arthritis - Steroid injections into your carpal tunnel area
to reduce inflammation - Physiotherapy
- If swelling occurs, use a cold pack to reduce
- Surgery treatment - if non-surgical treatment
doesnt help, surgery may be recommended for
serious cases. This is done in one day by giving
local anesthesia. The surgery is known as carpal
tunnel release. This surgery has two techniques
and your doctor will suggest the ideal one for
your condition. - Open release surgery - An incision is made in
your wrist and palm and the surgeon locates the
flexor retinaculum (a strong band of tissue
within the carpal tunnel that wraps the median
nerve and the tendons that move the fingers). The
flexor retinaculum
4- is cut and released, with that, the pressure on
the median nerve is released then the skin is
stitched back together. - Endoscopic surgery- in this technique the doctor
uses a narrow telescope called an arthroscope.
This is used to see the structures of the carpal
tunnel from inside. In this procedure two small
incisions are made one in the wrist and one in
the palm and then the arthroscope is passed
through one incision and the surgical instruments
through the other. The surgeon will be able to
see the structures of the carpal tunnel on the
monitor while using the surgical instruments to
release the flexor retinaculum. The incisions are
closed either with stitches or small paper tapes
(steristrips). - Recovery - Endoscopic carpal tunnel release
usually has a quicker recovery time it has less
postoperative pain and causes less scarring than
open release surgery. - However, this endoscopic type of surgery is not
suitable for all people. - Postoperative recovery- usually the recovery
from the surgery happens very quick and have
very fewer complications. 95 of people who
undergo carpal tunnel release surgery get relief
from the symptoms. - It is very important to follow the post-operative
recovery guidelines. You will be recommended to
use a splint. This helps you to restrict hand
movement and promote healing. Gentle hand
exercises may also be recommended. - If your condition is long term (chronic) then the
symptoms may take a longer time to disappear. - Prevention
- Carpal tunnel syndrome is caused by multiple
factors, you can try to prevent carpal tunnel
syndrome by making lifestyle changes that help
decrease some of your risk factors - Try to maintain your levels of diabetes, high
blood pressure, and arthritis that may lessen
your risk of developing carpal tunnel syndrome. - Paying cautious attention to hand posture and
avoiding activities that overstretch your wrist
are also significant approaches for reducing
symptoms. - Physical therapy exercises may be co-operative as
well. - Position your wrist straight while sleeping.
5- Avoid curling your wrists repeatedly.
- Take frequent breaks while working.
- Perform exercises and warm-ups before and after
activities.
