Trigger Finger

What is it?

Trigger finger is a type of tendinitis which develops in the tendons which bend the fingers. It is a common problem because of the way that the hand is made, which may be a little different than you would suspect. There are no muscles in the fingers themselves. We actually move our fingers by remote control. Muscles in the forearm are connected to the finger bones by smooth, flexible strings, called tendons. The muscles pull on the tendons, which then bend the finger joints.

This arrangement allows the fingers to be slender, yet have all the strength of the large muscles in the forearm.

What can you do to help?

Ice for five to fifteen minutes at a time on the area which is most swollen and tender.

"Over the counter" non-steroidal anti inflammatory medication (NSAID), such as aspirin, ibuprofen, naprosyn, or ketoprofen. Check with your pharmacist regarding possible side effects and drug interactions.

Avoid activities which involve a sustained grip. Hold off on the use of grip strengthening devices or exercises involving repetitive squeezing - these put stress on the irritated tendon.

If fingers bend and lock during the night and are painful to straighten in the morning, it may be helpful to wear a splint to keep them straight while sleeping. One way to do this is to use a wrist support splint as shown below: A wrist splint designed to be worn on the opposite hand may be worn with the forearm end turned out to form a palm sided support for the fingers. This may be helpful as an interim measure.

Wait and watch.

What can a therapist do to help?

Help identify aggravating activities and suggest alternative postures.

Massage, heat, ice and other treatments aimed at making the area more comfortable.

Sometimes a custom splint which limits finger bending can help.

What can a doctor do to help?

Confirm that this actually is the problem.

Prescribe stronger NSAID medication or cortisone type medication.

Prescribe hand therapy and/or a custom prescription splint.

Give a cortisone shot into the sore area. Usually, no more than two shots are given into one finger because more may lead to complications, such as tendon rupture.

Perform surgery.

How successful is treatment?

Cortisone shots usually provide relief, although this is temporary nearly half of the time.

Surgery provides permanent relief from locking and triggering in the great majority of patients.

Swelling, stiffness, aches and pains in the fingers may well be due to other problems, and may persist to some extent following any form of treatment. Many patients with trigger fingers also have a tendency to have swelling, stiffness and soreness of the moving parts of their hands, and that is not changed by surgery.

With this in mind, the great majority of patients are improved with appropriate treatment.

What happens if you have no treatment?

It depends on how much it is bothering you - it really is a quality of life issue. This is not a problem which can spread to other parts of your body. Some people have triggering which resolves over a period of months.

Other than persistent pain and stiffness, the additional problem which may develop is a permanent partial bend of the middle joint of the finger. This is more likely the longer triggering has been going on.

The main reason to do surgery is to relieve pain. Some people will have a mild problem which flares up from time to time, and treat it themselves or ignore it. Others will have a severe problem which prevents them from doing many things with their finger, and feel that they have no choice but to have surgery.
