Trigger Finger, also known as stenosing tenosynovitis, is a common condition that affects the tendons responsible for bending the fingers or thumb. It occurs when inflammation narrows the space within the tendon sheath, making finger movement difficult and sometimes causing the finger to lock or catch during motion.
This condition can interfere with daily activities such as gripping objects, typing, or opening jars. Dr. Alejandro Badia specializes in minimally invasive treatments for Trigger Finger, helping patients restore comfort, mobility, and hand function with personalized care.
Patient Success Stories
Many patients suffering from Trigger Finger experience frustration due to pain, stiffness, and fingers that become stuck in a bent position. Through advanced treatment options and minimally invasive techniques, Dr. Badia has helped patients regain smooth hand movement and return to their normal activities with confidence.

Understanding Trigger Finger
Trigger Finger develops when the flexor tendon that bends the finger becomes irritated or inflamed. Over time, the tendon may thicken, making it difficult to glide smoothly through the protective pulley system inside the finger.
As the condition progresses, patients may notice clicking sensations, stiffness, or locking of the finger during movement. In severe cases, the finger can become temporarily stuck in a bent position and may require assistance to straighten.
Trigger Finger most commonly affects the thumb, ring finger, or middle finger, although any finger can be involved.
Common Symptoms
Patients with Trigger Finger may experience symptoms that gradually worsen over time, including:
Catching or Popping Sensation
Patients commonly experience a locking, catching, or popping sensation in the finger or thumb joints when trying to straighten the digit.
Morning Stiffness
Stiffness or catching tends to be worse after periods of inactivity, particularly when waking up in the morning, and often loosens with movement.
Pain and Tender Lump
Pain often occurs when bending or straightening the affected finger, and a tender lump may develop in the palm at the base of the digit.
Swelling
Swelling in the affected finger or thumb is a common symptom, sometimes following a period of heavy or repetitive hand use.
Causes and Risk Factors
Trigger Finger is often caused by repetitive gripping motions or activities that place strain on the hand and fingers. Inflammation within the tendon sheath can limit normal tendon movement and lead to mechanical catching.
Several factors may increase the risk of developing Trigger Finger, including:
- Repetitive hand use or gripping activities
- Diabetes
- Rheumatoid arthritis
- Previous hand injuries
- Occupations requiring prolonged hand strain
- Age, especially between 40 and 60 years old
- More common occurrence in women
Certain hobbies, sports, or work-related activities may also contribute to tendon irritation over time.
How It Is Diagnosed
Trigger Finger is typically diagnosed through a physical examination and evaluation of symptoms. Dr. Badia carefully assesses finger movement, areas of tenderness, and whether the tendon catches or locks during motion.
In most cases, imaging studies are not necessary. However, X-rays or ultrasound imaging may occasionally be used to rule out other hand conditions or evaluate associated inflammation.
Early diagnosis can help prevent worsening symptoms and improve treatment outcomes.
Treatment Options for Trigger Finger
Trigger finger is not a dangerous condition, and the decision to have surgery is a personal one based on how severe your symptoms are and whether nonsurgical options have failed.
Non-Surgical Treatment
If symptoms are mild, conservative treatment options can be very effective and may include:
- Resting the affected finger
- Over-the-counter medications (NSAIDs or acetaminophen) to relieve pain
Steroid Injections
Dr. Badia may choose to inject a corticosteroid—a powerful anti-inflammatory medication—around the irritated tendon. In some cases, a second injection is needed.
Injections are less likely to provide permanent relief if you have had the triggering for a long time or if you have associated medical problems, like diabetes.
Surgical Treatment
If injections fail or the finger is stuck bent, surgery can prevent permanent stiffness. The goal is to widen the tendon sheath tunnel.
Performed as an outpatient procedure under local anesthesia, the tunnel is cut through a small incision or with the tip of a needle. Patients are encouraged to move their fingers immediately after surgery.
