You may need an operation to treat trigger finger if all other types of treatment haven't worked or if another condition e. g. rheumatoid arthritis is the cause. Surgery is very effective and is usually a permanent solution to the problem. You will usually be given a local anesthetic in the palm of your hand to numb the area. Sometimes a regional anesthetic (to numb your entire arm) or a general anesthetic (so you sleep throughout) is used instead. Your surgeon will make a small cut into the palm of your hand and will release the tendon from the part of the sheath it was catching on. The wound will be closed using stitches and covered with a small dressing. You will need to keep the dressing in place for a week or 2 after the operation.
