Trigger finger

Overview

Trigger finger is a condition that affects the tendons in the fingers, causing them to become stuck in a bent position. This can be a painful and frustrating experience, but with the right treatment, it is possible to alleviate the symptoms. Trigger finger is more common in women over the age of 50, and it is often associated with conditions such as diabetes, low thyroid function, and rheumatoid arthritis.

Types of Trigger finger

There are several types of trigger finger, including:

• Classical trigger finger: This is the most common type of trigger finger, characterized by a sudden snapping or locking of the finger in a bent position.
• Multiplex trigger finger: This type of trigger finger affects multiple fingers simultaneously.
• Persistent trigger finger: This type of trigger finger is characterized by persistent pain and stiffness in the affected finger.

Causes of Trigger finger

Trigger finger occurs when the tendon that controls the finger becomes stuck or inflamed in the tendon sheath. This can happen due to a variety of factors, including:

• Swelling or inflammation in the tendon sheath.
• A small lump or nodule on the tendon.
• Repetitive strain or overuse of the affected finger.
• Underlying medical conditions, such as diabetes or rheumatoid arthritis.

Risk Factors of Trigger finger

Several factors may increase the risk of developing trigger finger, including:

• Age: Trigger finger is more common in people over the age of 50.
• Gender: Women are more likely to develop trigger finger than men.
• Underlying medical conditions: Conditions such as diabetes, low thyroid function, and rheumatoid arthritis may increase the risk of developing trigger finger.
• Repetitive strain: Repeatedly straining or overusing the affected finger may increase the risk of developing trigger finger.

Preventions of Trigger finger

While there is no surefire way to prevent trigger finger, there are several steps you can take to reduce your risk of developing the condition. These include:

• Wearing gloves or using protective gear when engaging in activities that may put repetitive strain on your fingers.
• Taking regular breaks to rest your fingers and hands.
• Maintaining proper posture and alignment when performing activities that may put strain on your fingers.

Complications

If left untreated, trigger finger can lead to several complications, including:

• Chronic pain and stiffness.
• Permanent damage to the affected tendon.
• Difficulty performing daily activities due to limited range of motion.

Diagnosis of Trigger finger

Diagnosing trigger finger typically involves a combination of physical examination, medical history, and imaging tests. A healthcare provider may perform the following tests to diagnose trigger finger:

• Physical examination: A physical examination may be performed to assess any visible signs of inflammation or swelling in the affected finger.
• Medical history: A healthcare provider may take a detailed medical history to assess any underlying medical conditions that may be contributing to trigger finger.
• Imaging tests: Imaging tests such as X-rays or MRI scans may be used to assess any structural damage or inflammation in the affected tendon.

Treatment for Trigger finger

There are several treatment options available for trigger finger, including:

• Splinting: Wearing a splint or immobilizing device to help maintain proper alignment and reduce strain on the affected tendon.
• Steroid injections: Injecting steroids into the affected tendon sheath to reduce inflammation and relieve pain.
• Surgery: Surgical procedures such as tenoscopy or tendon release may be performed to relieve pressure on the affected tendon and restore normal function.
