Trigger Finger and Trigger Thumb

Have you noticed your thumb or finger catching, snapping, or locking up when you try to bend or straighten it? If so, you are not alone — and more importantly, you do not have to simply live with it.

Trigger Thumb and finger occurs when the tendon sheath surrounding your thumb’s and finger’s flexor tendon becomes inflamed and narrowed, making smooth, pain-free movement a real challenge.

Whether it is struggling to button your shirt in the morning, gripping your steering wheel, or picking up everyday objects, we understand how much this condition can disrupt the life you want to be living.

That is exactly why we are here. At Complete Orthopedics, our hand and wrist specialists in New York will take the time to truly listen to your concerns, carefully evaluate your condition, and work with you to find the best path toward relief.

Many of our patients find significant improvement through simple, non-surgical treatments such as splinting, anti-inflammatory medications, or a well-placed corticosteroid injection to calm the inflammation.

If those options do not give you the lasting relief you deserve, our skilled surgeons can perform a minimally invasive trigger thumb and finger release —

A straightforward procedure with an excellent success rate that gets you back to using your thumb freely and comfortably. At Complete Orthopedics, we are not just treating your problem— we are helping you get back to the life you love.

How Common It Is and Who Gets It

Trigger finger and trigger thumb can affect individuals of all ages, but they are more common in adults, particularly those aged 40 to 60.

Women are more likely to develop these conditions, and certain medical conditions like diabetes and rheumatoid arthritis can increase the risk. Occupations that involve repetitive hand movements or excessive gripping also contribute to a higher incidence of these disorders.

Causes

Trigger finger and trigger thumb occur due to inflammation and thickening of the tendon sheath, most commonly around the A1 pulley.

This narrowing causes a restriction that prevents the tendon from sliding smoothly through the sheath, leading to pain and stiffness.

Repetitive motion, gripping, and underlying conditions such as diabetes and rheumatoid arthritis can contribute to tendon irritation and inflammation. In many cases, the exact cause of the inflammation is unknown.

How the Body Part Normally Works

The tendons in the fingers and thumb are housed in sheaths that allow for smooth movement when the digits bend and straighten. The A1 pulley, a fibrous structure, helps guide the tendons in their movement.

When inflammation causes the tendon to thicken, it cannot glide smoothly through the sheath, resulting in the “catching” or “locking” sensation typical of trigger finger and trigger thumb.

What You Might Feel

The primary symptom of trigger finger and trigger thumb is a “catching” or “locking” sensation during movement. This may start as a mild, intermittent issue but can progress to a point where the finger or thumb becomes locked in a flexed position. Additional symptoms include:

• Pain, particularly in the morning or with activities involving gripping
• A palpable nodule at the base of the affected finger or thumb
• Clicking or popping sounds when moving the affected digit
• In severe cases, permanent flexion of the finger or thumb

How Doctors Find the Problem

Trigger finger and thumb are usually diagnosed based on physical examination. The physician will assess the affected area for tenderness, swelling, and restricted movement.

Special tests such as the “triggering” or “catching” of the finger, as well as ultrasound or MRI, may be used to rule out other conditions, although these imaging studies are not typically necessary. Most diagnoses are made through clinical presentation alone.

Treatment Options

Non-Surgical Care

• Splinting: Splints are used to keep the affected finger or thumb in a neutral position, preventing movement that could aggravate the condition. Splints may be worn during the day or at night, depending on symptom severity.
• Corticosteroid Injections: For many patients, steroid injections into the tendon sheath can reduce inflammation and provide significant relief, especially in the early stages.
• Physical Therapy: Gentle exercises and stretches can improve the range of motion and reduce stiffness in the affected joint.

Surgical Care

If conservative treatments fail, surgery may be necessary. The two primary surgical options are:

• Percutaneous Release: A minimally invasive procedure that involves using a needle to cut the A1 pulley and relieve pressure on the tendon. While effective, this carries a risk of nerve damage and recurrence.
• Open Release Surgery: In more severe cases, or if percutaneous release is not suitable, open surgery may be performed. This involves removing or cutting the A1 pulley, allowing the tendon to move freely. It has a high success rate, though it carries a slightly higher risk of complications.

Recovery and What to Expect After Treatment

After surgery patient can start light activity from next day. Stitches removal after 10 days. PT for 2 weeks and back to all activity after 4 weeks.

Possible Risks or Side Effects

Complications of treatment for trigger finger and thumb include infection, nerve injury, scarring, and recurrence of symptoms.

Surgery, particularly the open release method, carries a higher risk of complications than conservative treatments, though most patients experience positive outcomes.

Long-Term Outlook

With proper treatment, the prognosis for trigger finger and thumb is generally good. Many patients achieve full recovery with nonsurgical treatments such as splinting and corticosteroid injections.

Surgical treatment has a high success rate, with most patients regaining full function. Recurrence of symptoms is rare, but it can happen, especially in more severe cases.

Summary and Takeaway

Trigger finger and trigger thumb are treatable conditions that cause pain, stiffness, and restricted movement due to tendon sheath inflammation.

While nonsurgical treatments like splinting and corticosteroid injections are often effective, surgery may be necessary in more severe cases.

With early intervention, the prognosis for both conditions is generally positive, and most patients regain full function after treatment.

Who Performs This Treatment

Orthopedic surgeons, hand surgeons, and physical therapists are typically involved in the diagnosis and treatment of trigger finger and thumb. Surgical intervention is often performed by orthopedic or hand surgeons specializing in upper extremity conditions.

When to See a Specialist

If you experience persistent pain, stiffness, or locking in your finger or thumb, it is important to see a specialist for evaluation and treatment. Early intervention can help prevent the condition from worsening.

How to Prevent It

Preventive measures include avoiding repetitive hand motions, taking breaks during activities that involve excessive gripping, and performing exercises to maintain flexibility and strength in the fingers and thumbs.

Nutrition and Bone or Joint Health

Maintaining a balanced diet rich in nutrients like calcium and vitamin D is important for joint health. Regular exercise and maintaining a healthy weight can also reduce the risk of developing trigger finger or thumb.

Activity and Lifestyle Modifications

Modifying activities to reduce strain on the hands and wrists, such as using ergonomic tools or taking frequent breaks, can help prevent the onset or progression of trigger finger and thumb.
