Trigger Finger

What is trigger finger?

Trigger finger is a problem with the hand that makes it hard for you to straighten one or more fingers after you bend them.

The medical term for trigger finger is stenosing tenosynovitis.

What is the cause?

A tendon is a band of strong fibrous tissue that connects a muscle to a bone. Tendons are covered by a protective sheath and glide easily through the sheath. Trigger finger can be caused by swelling of the sheath or by a knot in the tendon that makes it catch on the sheath.

What are the symptoms?

Symptoms include:

• a snapping feeling in the finger
• not being able to straighten the finger smoothly or at all (it may lock in place when it is bent and then straighten with a sudden jerk or “triggering” motion
• tenderness to the touch over the tendon, usually at the base of the finger or palm
• soreness in the affected finger or fingers

How is it diagnosed?

Your healthcare provider will ask about your symptoms and examine you.

How is trigger finger treated?

To reduce swelling and pain in the first day or two, your provider will probably tell you to:

• Put an ice pack, gel pack, or package of frozen vegetables, wrapped in a cloth, on the injured area every 3 to 4 hours for up to 20 minutes at a time.
• Take an anti-inflammatory medicine, such as ibuprofen, or other medicine as directed by your provider. Nonsteroidal anti-inflammatory medicines (NSAIDs), such as ibuprofen, may cause stomach bleeding and other problems. These risks increase with age. Read the label and take as directed. Unless recommended by your healthcare provider, do not take for more than 10 days.

Your provider may give your finger a shot of steroid medicine to reduce inflammation and swelling so the tendon can slide more easily through the sheath. In some cases you may need surgery to remove part of the tendon sheath.

How can I take care of myself?

• Try to rest your fingers, hand, and wrist as much as possible for as long as your provider recommends.
• Follow your treatment plan.
• Keep all appointments for provider visits or tests.
• Contact your healthcare provider if you have new or worsening symptoms.

When can I return to my normal activities?

You may return to your normal activities as long as there is not too much pain.

How can I help prevent trigger finger?

Since the cause of trigger finger is not known, there is no reliable way to prevent it.
