Stanley Loo Plastic SurgeonStanley Loo Plastic SurgeonTrigger finger, medically known as stenosing tenosynovitis, occurs when a tendon has difficulty gliding smoothly through the pulley system of the finger.
The affected finger may catch, click or lock when bending or straightening.
Symptoms can range from occasional clicking to painful locking that interferes with normal hand function.
Symptoms of Trigger Finger
Common symptoms include:
Clicking
Catching
Pain at the base of the finger
Finger stiffness
Locking
Difficulty straightening the finger
Symptoms that are worse with gripping
Trigger finger can affect the thumb as well as other fingers.
The current practice specifically notes that the ring, middle and index fingers can be affected, as well as the thumb.
What Causes Trigger Finger?
Trigger finger develops when inflammation or scarring around the tendon and its pulley system interferes with smooth tendon movement.
The tendon can become caught as it passes through the affected tunnel.
Diagnosis
Diagnosis is usually made through clinical examination.
The affected finger can often be identified from its characteristic catching or locking.
Before treatment, Stanley Loo assesses the hand to confirm the diagnosis and determine the most appropriate treatment.
Non-Surgical Treatment
Treatment may initially include:
Activity modification
Stretching
Ice
Anti-inflammatory treatment
Corticosteroid injection
The current practice describes local corticosteroid injection as an effective treatment for many patients.
When Is Surgery Considered?
Surgery may be considered when symptoms persist despite appropriate non-surgical treatment.
The current practice generally considers surgery after non-surgical approaches, including steroid injections, have failed.
Trigger Finger Release Surgery
Trigger finger release involves opening the constricted pulley so that the tendon can move freely.
The operation can be performed under local or general anaesthesia as a day procedure.
The current practice describes an incision at the hand or base of the finger followed by release of the affected tunnel.
Recovery
After surgery, the finger is gradually returned to movement according to postoperative instructions.
Swelling and tenderness around the incision are common initially.
Early movement may be encouraged to prevent stiffness, but heavy use should be avoided until healing permits.
