Trigger Finger Release by Operation
Our own practice has always been as follows:
- The Anaesthetist gives conscious sedation and an intravenous local anaesthetic Block (Bier's Block) to numb the forearm and the hand or a Wrist Block . The Local anaesthetic is kept in place and blood is kept out of the arm by means of a special tourniquet cuff.
- We make a small incision parallel to nearby palmar creases. Via this incision, we expose the flexor tendons, identify the ege of the pulley and carefully divide the pulley.
- The finger is then passively flexed and extended to ensure that the nodule is moving freely through the widened passage.
- The wound is sutured with 3 t0 4 small sutures and soft dressings with compression bandages are applied to the hand.
- Pre- and post-operative Physiotherapy is mandatory.
- The patient is encouraged from the beginning to move the hand through a full range and the Physiotherapists and Occupational Therapists help us to maintain that range through the healing process, sometimes by exercise and sometimes by wearing splints at night.
- We usually do only one hand at a time, leaving the other hand free for essential tasks.
Benefits experienced by most patients:
1. Improved mobility and function of the hand
2. Removal of the triggering
Negative Aspects:
1. Pain, swelling and bruising in the first few days requires elevation of the hand
2. Scar, almost insignificant
3. Surgical Complications - risk of infection, bleeding, haematoma, damage to a nerve.
3. Trigger finger may recur after a few years
