What Is Triggering Fingers?

Trigger finger, also known as stenosing tenosynovitis, is a common hand condition that can significantly impact hand function. It occurs due to irritation and thickening of the sheath surrounding the flexor tendons in the finger.

This thickening, particularly at the A1 pulley located where the finger meets the palm, obstructs the smooth movement of the tendon, leading to pain, catching, or a snapping sensation when you move your finger. In severe cases, the affected finger can become locked in a bent position.

Common Causes of Triggering Fingers

The exact cause of trigger finger is often unclear, but it is frequently linked to repetitive gripping or squeezing hand motions. Certain medical conditions, such as diabetes, rheumatoid arthritis, gout, pseudogout, sarcoidosis, and hypothyroidism, are associated with an increased risk. Some people may also have a genetic predisposition.

Trigger finger is most common in individuals between 40 and 60 years old and affects women more often than men. People whose work or hobbies involve frequent or intense gripping are also at higher risk. Any finger or the thumb can be affected, and it can occur in multiple digits on one or both hands at the same time

Treatment Options for Trigger Finger

The main goal of treating trigger finger is to eliminate catching or locking and restore comfortable, full range of motion. Most cases can be effectively managed without surgery using conservative methods. These include:

  • Activity modification: Reducing activities that involve making a fist can help rest the affected tendon.
  • Splinting: Immobilizing the affected finger in a straightened position, often overnight with a splint, can be helpful.
  • Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation.
  • Corticosteroid injections: These injections are considered a very safe and effective treatment for many patients with trigger finger. However, repeated injections (more than two or three) in the same finger should be avoided due to potential complications.
  • Physiotherapy: A physiotherapist can provide guidance on appropriate exercises, such as wrist stretches and fingertip bends, and recommend assistive devices to perform daily activities without straining the tendon. Physiotherapy techniques like heat, massage, finger stretches, and manual joint therapy may also be used.

If conservative treatments are not successful, surgical intervention may be necessary. This procedure, known as trigger finger release or A1 pulley release, is a quick procedure that can be performed with local anaesthesia or sedation. Surgery is generally preferred for children when conservative methods are ineffective, or the condition affects hand function.

While some mild cases of trigger finger may resolve on their own, cases with recurring or continuous pain, limited mobility, or a chronically bent finger will require treatment. Early diagnosis and treatment are important to prevent chronic inflammation and permanent changes to the tendon.
