Tips for Treating Trigger Finger Without Surgery
Has one of your fingers ever become stuck in a bent position, becoming painful and difficult to straighten after holding your cup of coffee? Or, does your finger click when you are holding a knife and fork? If so, then you may be experiencing trigger finger. Read on to learn more about this condition as well as and tips for .
What is , or ?
Stenosing tenosynovitis, commonly known as trigger finger, is a condition where the lining of the flexor tendon becomes thick or swollen. The increased thickness and swelling compress the tendon preventing it from gliding smoothly. This can cause the tendon to click or get stuck and locked. Prolonged irritation through repetitive use of the hand may cause scarring and the formation of nodules. The average age of onset is 50 or older, and evidence suggests the ring finger is most commonly affected, followed by the thumb, but all fingers can be affected.
Let’s review the basic anatomy of trigger finger. Each finger has tendons that run on the palm side of the finger that is responsible for flexing or bending the finger. These tendons are surrounded by a protective sheath and run through a system of pulleys that help to keep the tendon in place. In most cases, the most common location for developing trigger finger is at the base of the finger on the palm side of the hand at the large knuckle called the metacarpophalangeal joint (MCP). This is the area of the A1 pulley. You can think of the A1 pulley as the eye of a sewing needle and the flexor tendon in its sheath is a piece of thread. When the tendon sheath becomes swollen and irritated, it would be like trying to thread twine through a sewing needle; it would become stuck.
Signs and Symptoms
Trigger finger symptoms can look like:
- Stiffness in your finger
- Tenderness and/or a nodule at the base of the finger
- Locking of your finger in a bent position
- Popping or clicking when you move your finger
Causes and Risk Factors
The exact cause of trigger finger is not known. There are several factors that could contribute to trigger finger, including:
- Repetitive use of the hand
- Prolonged use of hand-held tools
- Local trauma to the hand/finger
- Degenerative forces and stress to the hand
How do you release a trigger finger at home?
is not always necessary and can include release at home. If you find your finger locks or “gets stuck” at home, a trigger finger can be released at home in a few, simple steps. First, place your fingers or entire hand in warm water for approximately 5-10 minutes. This will allow the tissues to relax and promote increased movement in the hand.
A heating pad could also be used. Once the hand is warmed up, gently try to make a fist and then straighten the fingers. Repeat this several times until the finger loosens. You may need to apply gentle pressure to the affected finger to assist in straightening the finger out.
Another technique to release a trigger finger is to locate the nodule in the palm in the area of the affected finger. Gently massage the area using a circular motion to gently release the tissues and attempt to straighten your fingers.
Can trigger finger be treated with therapy?
Yes, another option for trigger finger without surgery can be with therapy. There are several options when it comes to treating trigger fingers, including conservative treatment options or non-surgical management. An occupational therapist or hand therapist can guide you through the process of decreasing your trigger finger symptoms and improving how your hand works.
Heating treatments, such as a moist heating pad or paraffin wax can be applied to your hand to alleviate stiffness and prepare your hand for therapy. Your therapist will use various manual therapy techniques including stretching your fingers to improve your range of motion, and soft tissue massage to decrease stiffness and increase circulation to the area for healing.
Another option for treatment is using a small finger splint that can be made by your therapist. These small splints limit the affected finger from flexing or bending repetitively at the MCP joint or the large knuckle of the finger. By allowing the tendon to rest, the inflammation will decrease, and the triggering or locking of the finger should lessen. The finger splint is typically worn during times of activity during the day and can be used at nighttime as well.
In addition to techniques provided in therapy, your therapist will provide you with an exercise program to complete at home to maximize your range of motion and function of the hand.
What happens if trigger finger goes untreated?
Trigger finger and trigger thumb symptoms need to be addressed to maximize hand function and decrease pain. Inflammation, stiffness, and pain typically get worse when a trigger finger is left untreated, and you may find the affected finger is locking more frequently. This can impact your hand function and your quality of life.
Occupational Therapy Can Help
Trigger finger can have a significant impact on the use of your hand and your daily routine. Recognizing and addressing symptoms early is a key factor in treating trigger finger. Occupational therapy is an excellent avenue for conservative or non-surgical management of trigger finger and can help in the following ways:
- Providing a comprehensive home exercise program to encourage a range of motion and increased hand function.
- Fabricating a splint to promote the rest of the inflamed finger or thumb.
- Providing education on activity modification, including rest, to reduce irritation to the involved finger while maintaining the ability to participate in your daily activities.
- Using heating treatments and manual therapy techniques, including stretching and massage, maximize the function of your hand.
