ORTHOPEDIC CONCERN

Carpal Tunnel

Also called: carpal tunnel, wrist pain, numb fingers, hand pain

Carpal tunnel syndrome is a common condition caused by pressure on the median nerve as it passes through the wrist. It can cause numbness, tingling, pain and weakness in the hand and fingers, with symptoms often becoming particularly noticeable at night.

TYPICALLY OCCURS

Nerve compression, wrist swelling and repetitive hand use

TREATED BY

Carpal tunnel surgery, steroid injections and wrist splinting

Why it happens?

Carpal tunnel syndrome develops when the median nerve becomes compressed within a narrow passage in the wrist called the carpal tunnel. The median nerve provides sensation to the thumb, index finger, middle finger and part of the ring finger and also helps control some of the muscles around the thumb. Because the carpal tunnel has limited space, swelling or changes affecting the tissues within it can increase pressure on the nerve, interfering with normal nerve function and producing numbness, tingling or pain.

Several factors can increase the likelihood of this compression. Conditions that cause swelling or inflammation around the wrist may reduce the available space within the tunnel. Pregnancy and hormonal changes can contribute through fluid retention, while conditions such as diabetes, rheumatoid arthritis and thyroid disorders are also associated with an increased risk of carpal tunnel syndrome. Previous wrist fractures or injuries may alter the anatomy of the tunnel and place additional pressure on the median nerve. Some people may also naturally have a smaller carpal tunnel, making them more susceptible to symptoms.

Repetitive or prolonged wrist and hand activities may contribute, particularly when they involve forceful gripping, repeated wrist movements or sustained positions. However, carpal tunnel syndrome should not simply be considered a condition caused by typing or computer use, as its development is usually more complex. In some cases, no single cause can be identified. If compression continues, symptoms can become more frequent and the median nerve may gradually become impaired, potentially leading to reduced grip strength, difficulty with fine hand movements and weakness or wasting of muscles around the base of the thumb.

How far along is it?

Early

Occasional tingling or numbness develops in the thumb and fingers, commonly at night or after certain activities. Shaking or changing the position of the hand may temporarily relieve symptoms.

Moderate

Numbness, tingling or pain becomes more frequent and may occur during the day. Grip strength and fine hand movements can begin to feel less reliable, and symptoms may interfere with sleep or everyday tasks.

Advanced

Numbness may become persistent, with noticeable weakness, reduced dexterity or difficulty gripping objects. In more advanced cases, muscle wasting can develop around the base of the thumb.

Orthopaedics→

Occasional temporary tingling does not necessarily mean you have carpal tunnel syndrome. However, professional assessment is worthwhile when numbness, tingling or pain repeatedly affects the thumb and fingers, regularly wakes you at night or begins interfering with work and everyday activities.

It is particularly important to seek medical advice if numbness becomes persistent, your grip becomes weaker, you frequently drop objects or you notice muscle loss around the thumb. Prolonged or severe median nerve compression can lead to lasting nerve and muscle problems, so progressive symptoms should not be ignored.

Quick Questions:

What are the first signs of carpal tunnel syndrome?

Early symptoms commonly include tingling, pins and needles or numbness affecting the thumb, index and middle fingers and part of the ring finger. Symptoms are often worse at night and may initially come and go.

What causes carpal tunnel syndrome?

Carpal tunnel syndrome results from compression of the median nerve at the wrist. Several factors can contribute, including swelling, pregnancy, certain medical conditions, previous wrist injuries and activities involving repetitive or forceful wrist movements.

Can carpal tunnel syndrome go away on its own?

Symptoms can sometimes improve, particularly when they are mild or related to a temporary cause such as pregnancy. Persistent or worsening symptoms should be assessed because ongoing nerve compression can potentially cause lasting problems.

Does carpal tunnel syndrome always need surgery?

No. Depending on the severity and cause, initial management may include wrist splinting, activity modification or steroid injections. Surgery may be considered when symptoms are severe, other measures have not helped or there is evidence of significant nerve impairment.
