What kind of doctor treats Trigger Thumb?
An orthopedic surgeon, a doctor who treats bone, joint, and tendon problems, usually treats trigger thumb. A primary care doctor can often find it with an exam. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is trigger thumb?
Trigger thumb is trigger finger that affects the thumb. It is a condition that affects the tendons and keeps them from bending normally. The tendon slides through a tunnel called a sheath. If the tunnel swells and gets smaller, or the tendon has a bump, the tendon cannot slide smoothly. Then the thumb can catch, lock, or pop, as if you were squeezing a trigger.
Symptoms
Symptoms often start slowly and get worse over time.
- A tender lump at the base of the thumb on the palm side of the hand.
- A catching, popping, or locking feeling when you move the thumb.
- Pain when you bend or straighten the thumb.
- The thumb getting stuck in a bent position.
Stiffness and locking tend to be worse after periods of inactivity, such as when you wake up in the morning. In the worst cases, the thumb cannot be straightened at all without a doctor's help.
Causes and who gets it
Most cases have no clear cause. It is more common in women between the ages of 40 and 60. It is also more common in people with diabetes, rheumatoid arthritis, or amyloidosis. People who do repetitive gripping or pinching activities for work or fun are more likely to get it. Trigger finger is rare in children, though a condition called congenital trigger thumb can cause a child's thumb to lock in a bent position.
How doctors diagnose it
Your doctor can usually diagnose it by talking with you about your symptoms and examining your hand. X-rays or other tests are usually not needed. The doctor also looks for thickening or swelling at the base of the thumb.
Treatment
The goal of treatment is to reduce pain and help the tendon glide more freely. Most cases respond well to treatment that does not use surgery. It can sometimes get better on its own without any treatment.
- Rest your hand and avoid repetitive gripping or pinching.
- Wear a splint at night to keep the thumb straight while you sleep.
- Take anti-inflammatory medicines, such as ibuprofen or naproxen, to ease pain and swelling.
- Do gentle stretching exercises to lower stiffness and improve movement.
- Get a steroid injection, a shot of a strong anti-inflammatory medicine, given at the base of the thumb in the doctor's office.
In many cases, a steroid injection can resolve the condition. Steroid injections are less likely to work in people with trigger thumb. They may still help. People with diabetes should have their blood sugar checked closely after a steroid injection.
Surgery may be needed if symptoms are severe or do not get better with other treatments. It may also be needed if the thumb is stuck in a bent position and cannot be straightened. The surgery is called a trigger finger release. The doctor makes a small cut in the palm, or uses the tip of a needle, to open up the A1 pulley, a tunnel that holds the tendon close to the bone. Complications are rare but can include infection, stiffness, or return of symptoms. The cut usually heals within a few weeks, but it may take 4 to 6 months for swelling and stiffness to go away completely.
When to see a doctor
See a doctor if you think you have trigger thumb and your symptoms do not get better. See a doctor too if your symptoms stop you doing your usual daily activities. If your thumb stays locked in a bent position, get help, because it may not straighten without a doctor. After surgery, contact your surgeon right away if you notice signs of infection. These signs include redness, swelling, or warmth in your cut or hand, yellow or green drainage from the cut, and fever. If your trigger thumb comes back after surgery, contact your surgeon.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can examine your hand and talk with you about your symptoms. If a steroid injection or surgery is needed, they can refer you to a specialist.
Common questions
Is trigger thumb the same as trigger finger?
Yes, trigger thumb is trigger finger that affects the thumb.
Can trigger thumb go away on its own?
Yes, it can sometimes get better on its own without any treatment. If it does not, resting the thumb, wearing a splint, or getting a steroid injection may help.
Do steroid injections work for trigger thumb?
They can help, but they are less likely to work for trigger thumb than for some other cases. In many cases, a steroid injection can resolve the condition. If injections do not help, surgery is often recommended.
Does trigger thumb need surgery?
Not always, because most cases respond well to treatment that does not use surgery. Surgery may be needed if the thumb is stuck in a bent position and cannot be straightened.
