Amputations/Pain

What is Trigger Finger?

Trigger finger is a condition in which one of the fingers becomes “stuck” in a bent position and often needs to be “popped” back out. Trigger finger occurs when the affected fingers tendon sheath becomes irritated and inflamed.   

This inflammation narrows the space around the tendon which interferes with the normal gliding motion 
of the tendon through the sheath.   

If trigger finger is severe, the finger may become locked in a bent position. Prolonged irritation of the tendon sheath can produce scarring, thickening and the formation of bumps (nodules) that impede the tendon’s motion even more.  

Trigger finger may start with a discomfort felt at the base of the affected finger, where the finger joins the palm of the hand. Often the area is sensitive to pressure along with the trademark painful «popping» and «catching» movement.   

Triggering of the finger is usually more pronounced in the morning, while firmly grasping an object or when straightening the finger.

Who is Susceptible to Trigger Finger?

People whose work or hobbies that require repetitive actions and strong gripping are at higher risk for developing trigger finger.   

Examples of such occupations include: 

receptionists or office positions
construction or manual laborers
assembly line workers
trucker drivers

While the cause is not always known, trigger fingers are commonly found in patients with conditions such as rheumatoid arthritis, gout and diabetes. Trigger finger is also more common in women than men.

About Trigger Finger Surgery

The goal of trigger finger treatment is to eliminate the swelling and catching/locking to allow for painless movement of the finger or thumb. Dr. Barbour will assess your unique symptoms to provide the best treatment for you. Non-surgical treatments can include anti-inflammatory medications or steroid injections. If your symptoms are severe or if conservative treatments haven’t helped, Dr. Barbour may suggest the following:

Percutaneous Trigger Release

In the comfort of our office Dr. Barbour will numb your hand completely. Once comfortable, he will insert a needle into the tissue around the affected tendon. Moving the needle and the finger beneath the skin helps break apart the constriction that’s blocking the smooth motion of the tendon.  

Percutaneous release is highly effective in most patients. Typically, patients experience immediate relief from the clicking and popping and have minimal soreness in the 24-48 hours following the procedure.

Trigger Finger Release Surgery

Working through a small incision near the base of the affected finger, Dr. Barbour can completely divide the constricted section of the tendon sheath. This procedure is performed in an operating room to maximize patient comfort and assure the entire restrictive band is released.  

This incision heals very well in most patients and is generally hidden in one of the creases of the palm. Sutures in the skin are usually removed in 2 weeks following the surgery. Occasionally, hand therapy is suggested to help patients regain strength and use of the finger after surgery.
