Trigger finger is a condition which arises due to tendons which get inflamed. This condition could occur when any kind of forceful action is done using the fingers.
In normal conditions the bending and the extension of the fingers takes place by the combined actions of the muscles and the tendons. The tendons are located in a protective sheath called the tendon sheath. These tendons glide easily through the tendon sheath which makes movement possible in normal unaffected conditions. Sometimes due to various reasons inflammation of the tendons takes place due to which the normal gliding movement of it is restricted.
Clicking is one of the initial signs of the trigger finger. Depending on the severity of the trigger finger, trigger finger surgery is advised.
Musicians, farmers, industrial workers, people suffering from arthritis, gout and some diabetics could suffer from trigger finger.
The condition can improve drastically with a small conservative trigger finger surgery.
The procedure for the surgery is quite simple and the chances of complications are very rare. The main aim of the surgery is to widen the tunnel. By doing so, the tendons can glide more easily without restricting their action.
The trigger finger surgery is performed on an outpatient basis under a local anesthetic.
A local anesthetic is injected around the operative site. By this the hand gets numbed and the procedure can be performed without causing any pain or sensation to the patient.
Near the palm, a small incision is made. A small cut is made through the tendon sheath (the tighter part of the sheath) through with mobility of the tendons can improve and thus preventing its locking. The incision which is made is very small, about 2-3 centimeters in length.
After completion of this procedure the incision area is sutured and bandaged. The sterile bandage is then removed after 10-15 days. Movement of the finger is encouraged. When slight finger movements take place, the post surgical adhesions are prevented and full recovery of the patient is expected.
Care that should be taken after trigger finger surgery includes:
- · Keeping the incision site clean after the surgery, this is prevents any post operative infection to occur. The incision will take about 7-8 weeks to heal completely. But the condition is seen to improve steadily.
- · During the healing period slow extension and flexion is advised. This would prevent adhesions.
- · Any kind of overuse of the fingers should not be done.
- · Instructions should be followed as given by the doctor. He will instruct the patient on some motions which the patient will have to perform.
Generally the trigger finger surgery has a very less chance of any sort of complication to occur. However, in some conditions the trigger finger may reoccur. This happens mostly when the release of the tendon sheath was inadequate. Other complications which again occur very rarely include infection or damage to the nerve located near the operation site, sometimes stiffness of the fingers occur by which again the mobility of the fingers is restricted.
Trigger finger surgery has a very high success rate.
