Trigger finger, also known as stenosing tenosynovitis, is a condition that makes it painful to bend and straighten the fingers, often accompanied by a popping or clicking sensation similar to pulling and releasing a trigger. This is caused by inflammation and narrowing of the A1 pulley, a band of tissue in the finger responsible for smooth finger movement.

Causes of Trigger Finger

Trigger finger occurs when the tendon controlling finger movement gets stuck due to inflammation in the A1 pulley, making it difficult for the tendon to slide through smoothly. The condition is more common in women between the ages of 40 and 60, and those with underlying conditions such as diabetes, rheumatoid arthritis, or carpal tunnel syndrome. It is also associated with repetitive hand movements, such as gripping tools or playing instruments. The ring finger and thumb are most commonly affected.

Symptoms of Trigger Finger

• Symptoms often begin with mild clicking or stiffness in the affected finger, progressing over time. Common symptoms include:
• Painful popping or locking sensation when bending or straightening the finger
• Stiffness, especially in the morning
• A tender bump or nodule at the base of the finger
• In severe cases, the finger may become stuck in a bent position and require force to straighten

 Diagnosing Trigger Finger

Trigger finger is typically diagnosed based on a patient’s symptoms, particularly the clicking or locking feeling. Physical examination is often enough for diagnosis, though imaging tests such as X-rays may be used to rule out other conditions.                                                                                                              

Several conditions can mimic the symptoms of trigger finger, including:

• De Quervain’s Tenosynovitis: Inflammation of the tendons at the base of the thumb, causing pain and difficulty moving the thumb, similar to trigger finger.
• Dupuytren’s Contracture: A thickening of the tissue beneath the skin of the palm, causing fingers to curl inward. Unlike trigger finger, there’s no popping or locking sensation.
• Carpal Tunnel Syndrome: Compression of the median nerve in the wrist, causing finger stiffness, tingling, and pain, which may resemble early symptoms of trigger finger.
• Arthritis: Osteoarthritis or rheumatoid arthritis can cause joint stiffness, swelling, and pain in the fingers, sometimes mimicking trigger finger.
• Flexor Tendon Injury: Trauma or injury to the tendons in the hand can lead to symptoms like pain and limited finger movement, similar to trigger finger.
• Ganglion Cyst: A fluid-filled bump on a tendon or joint in the hand can cause pain and restrict finger movement.

 Treatment Options for Trigger Finger

Both non-surgical and surgical options exist for treating trigger finger, depending on the severity of symptoms.

Conservative Treatments:

• Rest and Activity Modification: Avoiding activities that strain the finger can help reduce inflammation.
• Splinting: A splint can be worn at night to keep the finger straight, reducing stiffness and preventing the triggering sensation.
• Anti-Inflammatory Medications: Over-the-counter NSAIDs like ibuprofen can help reduce pain and swelling.
• Corticosteroid Injections: Steroid injections into the tendon sheath can reduce inflammation and alleviate symptoms, with success rates as high as 93% in non-diabetics. However, the relief may be temporary.

Shockwave Therapy: An Innovative Non-Surgical Option

At Aesthetics and Medical Lasers of Colorado, we offer shockwave therapy as an effective non-invasive treatment. This therapy uses acoustic waves to promote healing and tissue regeneration in the affected tendon, offering several benefits:

• Pain Relief: Reduces inflammation and improves blood flow, promoting faster healing.
• Non-Surgical: No incisions or injections, minimizing risks and recovery time.
• Long-Term Results: Stimulates tendon healing and regeneration for lasting recovery.
• Quick Improvement: Many patients experience improvement after just a few sessions.

Physical Therapy

Physical therapy can also be helpful, with exercises designed to strengthen the tendon and improve finger flexibility.

Surgical Treatment

If non-invasive treatments are ineffective or symptoms persist for over six months, surgery may be recommended. The most common procedure involves releasing the A1 pulley through a small incision, allowing the tendon to move more smoothly. While surgery is highly successful, it involves longer recovery times and potential complications.

Why Choose Shockwave Therapy?

Shockwave therapy offers a safe, effective alternative to surgery or repeated corticosteroid injections, by promoting the body’s natural healing process.
