Trigger Finger/Thumb (Stenosing Tenosynovitis)

Trigger finger, also known as stenosing tenosynovitis, is a condition where one of your fingers or thumbs gets stuck in a bent position and may straighten with a snap, much like pulling a trigger. It occurs when the tendons that control finger movement become inflamed or irritated, making movement painful and difficult.

At RAD Clinics, we provide effective treatment solutions for trigger finger, including ultrasound-guided injections, which are highly precise and minimally invasive.

Causes of Trigger Finger/Thumb

Trigger finger often results from repetitive gripping, strain, or overuse of the hand. Common causes include:

Repetitive hand movements (gripping, grasping)
Occupational or recreational activities requiring heavy hand use
Underlying health conditions such as rheumatoid arthritis or diabetes
Injuries to the hand or fingers

Symptoms of Trigger Finger/Thumb

The key symptoms of trigger finger include:

Stiffness or locking of the finger, especially in the morning
Pain at the base of the affected finger or thumb
A clicking or popping sensation when moving the finger
Swelling or tenderness in the palm
In severe cases, the finger may become stuck in a bent position

Anatomy of the Finger Tendons

The tendons in your fingers are responsible for controlling movement, running through a protective sheath that allows smooth, gliding motion. In trigger finger, the sheath becomes narrowed or inflamed, causing the tendon to catch, which limits mobility and causes discomfort.

The condition affects the flexor tendons located in the palm and along the fingers. When these tendons cannot glide smoothly due to inflammation, it results in the “locking” effect characteristic of trigger finger.

Diagnosis of Trigger Finger/Thumb

Diagnosing trigger finger typically involves a physical examination. At RAD Clinics, our specialists will check for the characteristic locking or stiffness of the finger and assess the pain level. In some cases, ultrasound imaging may be used to confirm the inflammation of the tendon sheath.

Cortisone Injections for Trigger Finger/Thumb

At RAD Clinics, we offer ultrasound-guided cortisone injections to treat trigger finger. This procedure involves using ultrasound technology to ensure precise placement of the injection directly into the inflamed tendon sheath.

Benefits of Ultrasound-Guided Cortisone Injections

Precision: Ultrasound-guided injections ensure the medication is delivered precisely where it’s needed, targeting the inflamed tendon.
Reduced Pain: The cortisone helps reduce inflammation and pain, allowing the tendon to glide smoothly.
Minimally Invasive: UG injections are a non-surgical option with minimal discomfort and no recovery time.
Quick Relief: Many patients experience a significant reduction in symptoms within a few days to weeks following the injection.

What to Expect During the Procedure

At RAD Clinics, ultrasound-guided cortisone injections for trigger finger are performed by our skilled specialists. Here’s what to expect:

Consultation: A detailed consultation to assess your condition and determine if UG cortisone injections are the right treatment for you.
Ultrasound Imaging: A small ultrasound device is used to visualise the tendons and ensure the cortisone is injected accurately.
Injection: The injection is administered directly into the tendon sheath under local anaesthetic to minimise discomfort.
Aftercare: Following the procedure, you may experience temporary numbness or swelling, but normal activities can usually resume immediately.

When to Seek Treatment

If you experience persistent pain, stiffness, or locking in your finger or thumb, it’s essential to seek medical advice. Trigger finger can worsen over time, potentially leading to permanent stiffness if left untreated. Early intervention at RAD Clinics can help prevent the condition from becoming more severe and may eliminate the need for surgery.

Seek treatment if:

The finger or thumb gets stuck in a bent position frequently
Pain or tenderness affects your ability to perform daily tasks
Symptoms do not improve with rest or conservative treatments
