Trigger Finger Release

What is trigger finger release?

Trigger finger release is a procedure to the treat trigger finger disorder, which is also known as “stenosing tenosynovitis”. There are flexor tendons connecting the forearm muscles to the thumb and fingers that facilitate finger curling and straightening. These tendons pass through tendon sheath structures attached to their respective fingers, including the thumb. The surgeon will create a small incision in the tendon sheath to create more room as these tendons become inflamed. This may be done as a percutaneous (“through skin”) surgery or open surgery. The surgeon will determine the appropriate treatment after considering a patient’s age, injury severity, activity levels and overall wrist joint health.

Who needs trigger finger release?

Patients will report that their fingers become stuck in a flexed position – as if they were pulling a trigger. This is accompanied with pain and stiffness. Patients also report “catching” and/or “locking” sensations in the affected fingers. The third finger (ring finger) is most often affected by this condition. Trigger finger may occur from overuse and/or repetitive motions in the wrist from activities like: farming, gardening, playing guitar, playing tennis, holding steering wheels, etc. Those who are female, diabetic, and have rheumatoid arthritis are also predisposed to trigger finger occurring. Trigger finger patients also report that their symptoms improve throughout the day as they use their fingers and thumb in day-to-day activities. Those who did not have their symptoms treated from conservative treatments like cortisone injections, physiotherapy, rest and/or splints, may be trigger finger release surgery candidates.

Open trigger finger release surgeries are preferred given the wrist joint region complexity. A tenosynovectomy may be done instead if percutaneous or open surgery methods are not applicable.
