Trigger Finger: Causes, Diagnosis, and Treatment
Overview
What Is Trigger Finger?
Trigger finger, medically known as stenosing tenosynovitis, is a condition that affects the tendons in your fingers or thumb. These tendons, which help bend and straighten your digits, pass through a protective sheath. When this sheath becomes inflamed or thickened, it narrows the space through which the tendon moves, causing the tendon to catch or “trigger” during finger movement.
This catching can cause the finger to lock in a bent position and then suddenly release, often with a painful snap. The condition can affect one or multiple fingers and is more common in people who perform repetitive gripping activities or have underlying conditions like diabetes or rheumatoid arthritis (Saldana, 1996).

Expert Analysis
Understanding Trigger Finger: Signs and Symptoms
Common symptoms of trigger finger include:
- Pain and tenderness at the base of the affected finger or thumb
- A popping or clicking sensation when moving the finger
- Finger stiffness, especially in the morning
- A noticeable bump or nodule in the palm near the base of the finger
- Finger locking or catching, which can sometimes make it difficult to straighten the finger fully
- Swelling and discomfort during finger movement (Stenosing Tenosynovitis, 2019).

What Causes Trigger Finger?
Trigger finger occurs due to inflammation or thickening of the flexor tendon sheath, often caused by:Whiplash typically results from:
- Repetitive hand use or prolonged gripping
- Direct injury or trauma to the palm or fingers
- Medical conditions such as diabetes, rheumatoid arthritis, or gout
- Age-related changes causing wear and tear of the tendons and sheath
- Genetic predisposition in some cases (Saldana, 1996).

What Happens if Trigger Finger Is Left Untreated?
If untreated, trigger finger may:
- Worsen, leading to persistent locking of the finger
- Cause permanent stiffness or decreased finger mobility
- Lead to decreased hand function and difficulty performing daily tasks
- Increase pain and swelling in the affected area
Early treatment is crucial to prevent these complications and restore hand function.

How Compass Pain and Wellness Treats Trigger Finger
Trigger finger can cause stiffness, pain, or locking of the affected finger, making gripping and hand movements difficult. These symptoms may interfere with work, daily activities, and emotional well-being, making routine tasks more challenging.
At Compass Pain and Wellness, the first treatment step is a detailed evaluation with your doctor to assess your condition. From there, our team creates a personalized plan of care tailored to your specific pathology. This may include advanced medical treatments along with supportive therapies to address pain and improve hand function.

Diagnosing Trigger Finger with Care
Our approach begins with:
- A detailed history of symptoms and hand use
- Physical examination focusing on finger movement, swelling, and tenderness
- Palpation to detect nodules or thickening near the tendon sheath
- Ultrasound imaging to assess tendon sheath inflammation and rule out other conditions if necessary (Stenosing Tenosynovitis, 2019).
Conservative Treatment Approaches for Trigger Finger
Splinting:
Immobilizing the affected finger to limit movement, reduce irritation, and allow healing.
Activity Modification:
Avoiding repetitive gripping or hand use that worsens symptoms.
Physical Therapy:
Stretching and strengthening exercises help restore mobility and reduce inflammation.
Acupuncture:
Stimulates blood flow and releases natural pain-relieving chemicals to ease discomfort.
Massage Therapy:
Focuses on reducing soft tissue tension around the affected tendons.
Shockwave and Tecar Therapy:
Promote tissue healing by improving circulation and reducing inflammation in the tendon sheath.
Chiropractic Care:
Addresses hand and wrist alignment and overall musculoskeletal health to reduce strain on tendons (Kim et al., 2019).


Advanced Treatment Approaches for Persistent Trigger Finger
Corticosteroid Injections:
Direct injection into the tendon sheath reduces inflammation and pain, often providing rapid relief.
PRP (Platelet-Rich Plasma) Therapy:
PRP injections encourage tendon healing and reduce chronic inflammation, serving as an alternative to steroids.
Surgical Release:
In refractory cases, a minimally invasive procedure can release the narrowed tendon sheath, restoring smooth tendon movement (Saldana, 1996).
