Conditions Covered Under This Heading

• Carpal tunnel syndrome — night numbness, loss of dexterity in fine tasks
• Trigger finger — catching and locking of the finger
• Tennis elbow — outer elbow pain increased by gripping
• Wrist fractures and non-union — see Trauma and Fracture Care
• Problems within the wrist joint and cartilage injuries — see Wrist Arthroscopy
• Ganglion cysts, tendon sheath problems and wrist osteoarthritis

Finding the Source of Numbness

The most common error with hand numbness is to assume every picture is carpal tunnel syndrome. Which fingers are numb points the way:

• Thumb, index and middle fingers: the median nerve — carpal tunnel syndrome
• Outer half of the ring finger and the little finger: the ulnar nerve — usually compression at the elbow
• Widespread numbness across the hand that changes with neck movement: nerve compression arising from the neck

In some patients compression is present at more than one level; the examination therefore covers the whole path from the neck to the fingertips. Nerve conduction studies clarify the distinction where needed.

Assessment

1. History: distribution of symptoms, waking at night, occupational hand use, history of injury, accompanying conditions (diabetes, thyroid, rheumatological disease).
2. Examination: sensation, grip and pinch strength, tendon movements, range of joint movement, nerve compression tests.
3. X-ray: for fracture, osteoarthritis and alignment.
4. Nerve conduction studies: to determine the site and degree of nerve compression; ultrasound / MRI for tendon, cyst and soft tissue problems.

Treatment Approach

For a significant proportion of hand problems treatment begins without surgery: activity modification, splinting, targeted exercise and pain management. Injection treatments are used in selected cases.

Surgery is considered where non-surgical treatment has not worked, where advanced nerve compression is found, or where there is muscle wasting or a risk of permanent loss of function. Two points determine the outcome in hand surgery:

• Early movement: hand tissues are prone to adhesion; starting the movements the physician permits on time prevents stiffness
• Swelling management: keeping the hand above heart level and moving the fingers reduces swelling and stiffness

Outcomes vary from person to person; no guarantee of a specific result or timeframe is given.

When Should You Seek Assessment?

• If you wake at night with numb hands
• If your finger catches or locks
• If your dexterity in fine tasks has decreased or you drop things
• If you have noticed thinning at the base of the thumb or in the hand
• If pain and swelling persist after a wrist injury

When to Seek Medical Help Without Delay

• Inability to bend or straighten a finger after a cut (this may be a tendon injury)
• Coldness, pallor, loss of sensation or absence of a pulse in the hand
• Redness, widespread swelling, severe pain and fever in the hand (suspected infection)
• High-pressure injection injuries (paint, grease gun) — an emergency even if they look minor
• Obvious deformity after injury with inability to move the wrist

These findings require urgent assessment. Outside office hours, go to the nearest emergency department.

Frequently Asked Questions

Is the numbness in my hand coming from my neck?

It may be. Which fingers are numb, and whether the numbness changes with neck movement, points the way. The examination covers the whole path from the neck to the fingertips; nerve conduction studies clarify the distinction where needed.

Does a ganglion cyst need surgery?

Not always. Cysts that cause no pain and do not limit function can be observed, and some shrink on their own. If there is pain, growth or loss of function, treatment is considered.

Will wearing a splint weaken my muscles?

Prolonged and unnecessary use can lead to weakness. A splint is therefore generally used for defined periods (for example at night) and on medical advice, together with an exercise programme.

When can I work after hand surgery?

The timeframe varies with the procedure, how much your work involves the hand, and your recovery. Light use is generally resumed early; return to work requiring heavy gripping is planned gradually.

Why does my hand still swell after surgery?

Swelling is a natural part of healing and can last for weeks. Keeping the hand above heart level and moving the fingers regularly reduces swelling and the stiffness that follows it.

I have diabetes — why are hand problems more common?

Diabetes is associated with carpal tunnel syndrome, trigger finger and thickening of the hand tissues. Blood glucose control is assessed as part of the treatment plan.
