Trigger Finger

Overview

Trigger finger, medically known as stenosing tenosynovitis, is a common condition characterized by the locking or catching of a finger or thumb during movement. This occurs due to inflammation and narrowing of the tendon sheath, particularly affecting the flexor tendons that allow fingers to bend. Trigger finger can significantly impair hand function and quality of life, making it essential to understand its symptoms, causes, and treatment options.

Introduction

Trigger finger predominantly affects adults, especially women aged 40-60, though it can also occur in children. The condition often manifests in the thumb or ring finger and is caused by repetitive hand movements or underlying health conditions such as diabetes, rheumatoid arthritis, and hypothyroidism. In India, the prevalence of trigger finger is rising due to increased use of digital devices and repetitive manual tasks in various occupations.

Symptoms

Common symptoms of trigger finger include:
– Snapping or Clicking Sensation: A painful clicking sound when bending or straightening the affected finger.
– Stiffness: Particularly noticeable in the morning or after periods of inactivity.
– Nodule Formation: A small bump at the base of the affected finger, often tender to touch.
– Locked Finger: In severe cases, the finger may become stuck in a bent position.

Symptoms typically worsen over time and may interfere with daily activities such as gripping or holding objects.

Causes

The exact cause of the trigger finger is multifactorial. Key contributors include:
– Repetitive Hand Use: Frequent gripping or repetitive motions can irritate the tendon sheath.
– Comorbid Conditions: Diseases such as diabetes, gout, and rheumatoid arthritis increase susceptibility.
– Anatomical Variations: Some individuals may have structural differences in their tendons or sheaths that predispose them to this condition.

In children, the trigger finger may result from developmental issues where the tendon does not fit properly within its sheath.

Treatment

Treatment for trigger finger varies based on severity:
– Conservative Approaches:
– Rest and Activity Modification: Reducing activities that exacerbate symptoms.
– Splinting: Using a splint to immobilize the affected finger can help alleviate symptoms.
– Corticosteroid Injections: These can reduce inflammation and swelling around the tendon.

– Surgical Options:
– If conservative treatments fail, surgery may be necessary. The procedure involves releasing the constricted tendon sheath through a small incision in the palm. Recovery is typically quick, allowing patients to resume normal activities shortly after surgery.

In India, access to these treatments varies widely; however, awareness about trigger finger is increasing among healthcare providers.

Prevention and Risk Factors

Preventive measures include:

– Ergonomic Adjustments: Modifying workspaces to reduce strain on hands.
– Regular Breaks: Taking breaks during repetitive tasks can help prevent overuse injuries.
– Strengthening Exercises: Engaging in hand exercises to maintain flexibility and strength.

Risk factors for developing trigger finger include:

– Age (most common in individuals aged 40-60)
– Gender (more prevalent in women)
– Pre-existing health conditions (e.g., diabetes, rheumatoid arthritis)
