Trigger finger release surgery is a day surgery recommended for patients who continue to experience triggering of the finger/thumb even after they have undergone therapy and steroid injections. This video uses 3D animation to explain what happens during a trigger finger release surgery.
*Trigger finger or trigger thumb is a condition in which the finger or thumb gets stuck in a bent position, or if the patient feels a popping or clicking sensation when bending or straightening the affected finger/thumb.
The tendons of the finger flexor muscles glide in a tunnel which consists of five pulleys. The pulley at the base of the finger becomes swollen, making it hard for the tendon to glide smoothly through the pulley. This results in the pain or catching feeling when the patient tries to flex the affected finger. A trigger finger surgery is done to increase the space for your tendon to glide freely again.
Steps in the trigger finger release surgery:
1) The area on the palm is numbed by injecting a local anaesthetic
2) An incision of about one centimetre is made in your palm
3) Surgeon cuts the pulley that hinders the finger movement
4) The complete release of the tendons are verified
5) Incision is closed with sutures and a bandage is applied for the next few days before the review of your surgeon
