Understanding trigger finger 

Trigger finger, medically known as stenosing tenosynovitis or flexor tenosynovitis, is a common hand condition that affects the tendons in the fingers or thumb. This condition occurs when the tendons, which normally glide smoothly through the tendon sheath when the finger is bent or straightened, become inflamed or thickened. This can lead to difficulties in finger movement. 

Causes of trigger finger 

The exact cause of trigger finger is not always clear, but several factors can contribute to its development: 

Repetitive Motion: Frequent and repetitive hand and finger movements, such as gripping tools or typing, can strain the tendons and lead to a trigger finger. 

Underlying Medical Conditions: Certain medical conditions, such as diabetes and rheumatoid arthritis, are associated with an increased risk of trigger finger. 

Age and Gender: It is more common in women and individuals aged 40 and older. 

Symptoms of trigger finger 

The primary symptom of the trigger finger is the sensation of the affected finger or thumb catching or locking in a bent or straightened position. Other common signs and symptoms include: 

Pain: Pain or discomfort at the base of the affected finger or thumb. 

Stiffness: Stiffness in the affected digit, makes it challenging to move. 

Clicking Sensation: A clicking or popping sensation when the finger is moved. 

Swelling: Swelling and tenderness at the base of the finger. 

Treatment for trigger finger 

The treatment of the trigger finger depends on the severity of the condition. Common approaches include: 

Consult with an expert: An Accredited Hand Therapist is a physiotherapist or occupational therapist with expertise in the finger, hand, wrist, elbow, and shoulder.

Rest and Immobilisation: Resting the affected hand and avoiding activities exacerbating symptoms can help reduce inflammation. Immobilisation with an orthosis or brace may also be recommended. 

Medications: Over-the-counter pain relievers or prescribed medications may be used to manage pain and inflammation. 

Hand Therapy: An Accredited hand Therapist can teach you exercises to improve finger flexibility and strength. 

Corticosteroid Injections: Injections of corticosteroids into the tendon sheath can reduce inflammation and alleviate symptoms. 

Surgery: In cases where conservative treatments are ineffective, surgery may be considered to release the affected tendon sheath. 

Recovery and rehabilitation 

The recovery period for the trigger finger can vary depending on the severity of the condition and the chosen treatment approach. Here are some essential points to consider during the recovery process: 

Follow Advice: Adhere to the treatment plan recommended by your Accredited Hand Therapist. 

Rehabilitation Exercises: Use rehabilitation exercises as prescribed to improve finger mobility and strength. 

Ergonomic Changes: Make ergonomic adjustments in your daily activities to reduce strain on the affected hand. 

Protection: Protect the affected hand from excessive strain and overuse. 

Patience: Recovery from the trigger finger can take time. Be patient and allow the affected tendon to heal properly.
