During this minimally-invasive procedure, the surgeon opens a narrowed tendon pulley at the base of the finger or thumb affected by trigger digit. Opening the pulley prevents the nodule from catching, allowing the affected digit to flex and extend normally with no triggering or pain.
The patient is positioned so that the palm of the hand is clearly visible to the surgeon. Local or general anesthesia is administered and the area is cleansed and sterilized.
Accessing the Hand
After the hand is prepped, a tourniquet is applied. A small incision is made in the palm of the hand over the pulley to be released. The skin and soft tissue are spread to expose the tendon and pulley. The nerves are protected throughout the procedure.
Releasing the Pulley
The surgeon uses surgical scissors or a scalpel to carefully divide the pulley, releasing the constriction on the tendon. The cutting of this pulley does impact finger function negatively.
End of Procedure
The incision is closed with sutures, and the hand is bandaged. Pain medication is administered and the patient is able to return home the same day. Finger motion is encouraged after surgery as therapy. Assisted hand therapy may also be recommended.
