Is Trigger Finger More Common in Certain Professions?

Sometimes the tools we use to build a better future end up taking a toll on us. For many professionals, repetitive movements and constant hand use are an essential part of their job. Still, over time, these actions may contribute to a common condition known as trigger finger. Whether you’re a builder, a musician, or a writer, understanding the causes, symptoms, and treatments of trigger finger is crucial for maintaining optimal hand health and preventing further damage.

This blog explores the connection between trigger finger and specific professions, guiding you on how to identify, treat, and avoid this condition.

What is Trigger Finger?

Trigger finger, medically termed "stenosing tenosynovitis," occurs when the tendons in your fingers or thumbs become irritated, inflamed, or thickened. This irritation can make it difficult for the tendon to move smoothly within its sheath, leading to a "locking" or "clicking" sensation when bending or straightening a finger. Over time, the condition can worsen, leaving the affected finger stuck in a bent position in severe cases.

Think of tendons as the ropes that pull your fingers to move. When the rope gets stuck or swollen at certain points, movement gets restricted. That’s exactly what happens in trigger finger.

What Causes Trigger Finger?

1. Repetitive Hand Movements

Repeatedly gripping, grasping, or putting pressure on your fingers can strain the tendons in your hands. Over time, this constant wear can lead to irritation and inflammation, one of the main causes of trigger finger.

2. Occupational and Recreational Activities

Many activities requiring the repetitive use of hands, such as playing a musical instrument, operating machinery, or gardening, can overburden the tendons. Even recreational activities, like knitting, can cause trigger finger if done for prolonged periods without breaks.

3. Underlying Health Conditions

Medical issues like rheumatoid arthritis and diabetes are linked to a higher risk of developing trigger finger. These conditions often cause inflammation or affect tendon health, making the hands more vulnerable to the condition.

4. Hand or Finger Injuries

Trauma or injuries to the hand can cause scarring or inflammation in the tendons, triggering similar symptoms to stenosing tenosynovitis.

Professions at Higher Risk of Trigger Finger

Some jobs or industries inherently place more strain on the tendons in our fingers. Here are a few professions most commonly affected:

1. Manual Labourers

Positions in construction, farming, and manufacturing often involve heavy use of the hands. Workers perform gripping, pulling, or repetitive tasks, which increases pressure on their tendons.

2. Musicians

Musicians, especially pianists and guitarists, are often at risk due to the repetitive finger movements required to master their instruments.

3. Hairdressers

Regular use of scissors and other styling tools limits hairdressers in terms of rest. This occupation often sees issues like trigger finger due to repeated gripping motions.

4. Office Workers

Constant typing and mouse use might seem harmless, but over time, they can cause strain, including trigger finger, particularly in people without ergonomic desk setups.

5. Athletes

Athletes like climbers or weightlifters frequently rely on grip strength, and overuse of this motion can lead to tendon inflammation. Trigger finger and other repetitive strain injuries are closely linked with intense training routines.

Identifying the connection between your profession and trigger finger can help you take preventive measures.

Recognising the Symptoms of Trigger Finger

Spotting the signs early is crucial for a better treatment outcome. Here’s what you need to look out for:

• Stiffness, particularly in the morning or after prolonged inactivity.
• Pain, especially at the base of the affected finger or thumb.
• Clicking or Popping Sensation when bending or straightening the finger.
• Swelling or Tenderness in the palm near the base of the affected digit.
• Locking or sticking in a bent or straightened position. Severe cases might leave your finger stuck entirely.

If you experience these symptoms, consider seeking professional medical advice for proper diagnosis.

Diagnosing and Common Treatments for Trigger Finger

Trigger finger is typically diagnosed during a physical examination where specialists check for stiffness, pain, or locking. If required, doctors may use ultrasound imaging for confirmation.

Treatment Options:

1. Rest and Modifications:

• • Reducing or avoiding the activity causing stress to the tendons can prevent the condition from worsening.
  • Ergonomic tools and wrist supports can help alleviate strain.

2. Splinting:

• • Splints hold the affected finger in an extended position, which can reduce pain and inflammation by allowing the tendon to rest.

3. Trigger Finger Injection:

• • Cortisone injections are a popular, non-invasive option. They reduce inflammation and allow the tendon to resume normal movement. Ultrasound-guided cortisone injections ensure pinpoint accuracy for better results with minimal discomfort.
  • Many patients experience relief within a few days after the injection.

4. Surgery:

• • For severe or persistent cases, surgery may be necessary to release the tendon sheath and restore smooth movement. However, this is usually considered a last resort when other treatments fail.

When Should You Seek Treatment?

Ignoring trigger finger can lead to worsening symptoms and potentially permanent damage. Seek professional advice if:

• You experience frequent locking or stiffness in your finger or thumb.
• Pain interferes with everyday tasks.
• Rest or over-the-counter treatments don’t provide relief.

Early diagnosis and appropriate trigger finger treatment are key to avoiding surgery and improving your quality of life.

Preventing Trigger Finger

While some risk factors may be out of your control, you can take steps to reduce your risk of developing trigger finger:

• Use ergonomic tools and adjust workstations to minimise strain.
• Take regular breaks during repetitive tasks like typing or gripping.
• Perform hand stretches and exercises to maintain tendon flexibility.
• Stay hydrated and maintain a healthy diet, particularly if you have conditions like diabetes or arthritis.

Take Action for Healthier Hands

Trigger finger can affect anyone, but knowing its causes, symptoms, and treatments puts you one step closer to protecting your hands and maintaining productivity in your profession. Professionals prone to repetitive movements must take preventive measures seriously.

Should symptoms persist, consider expert advice from a professional physiotherapist. Our ultrasound-guided trigger finger injections offer precise and effective relief for busy professionals. Why wait for the problem to worsen?
