Also known as stenosing tenosynovitis, Trigger finger is a disease in which one of the fingers gets stuck in a twisted position. Your finger may unbend with a snap as a trigger being pulled and unrestricted.

Trigger finger takes place when inflammation narrows the space in the sheath around the tendon in the affected finger. In case this condition is severe, your finger may become locked in a twisted point.

People who are involved in repeated gripping actions are more prone to get this condition than others. It is also common in women and in those who suffer from diabetes. The cure for this condition depends on its severity.

How Do You Know If You Have Trigger Finger?

The symptoms of trigger finger range from mild to severe such as:

  • Finger stiffness, specifically during the morning
  • A clicking feeling as you move the finger
  • Finger locked in a bent position that you cannot straighten
  • Tenderness in the palm at the bottom of the finger
  • Finger locking in a bent point, which unexpectedly pops straight

Trigger finger generally affects the thumb or the middle or ring finger. Generally, more than a single digit may get affected and both hands may get affected at a time. Triggering is typically more pronounced in the morning, while grasping something or when straighten the finger.

Surgical Treatment of Trigger Finger

Surgical treatment includes cutting through the affected part of the tendon sheath that joins the tendon to the bone in the finger in order to enable the tendon to move without any problem.

The intensity of your pain will help to decide if you should have a surgery or not or if it is associated with other medical issues like rheumatoid arthritis.

Generally, trigger finger is an irritation rather than an alarming disease, but if not treated, the affected finger or thumb may become always stuck in a bent or a straightened position. This may make it hard to perform everyday tasks.

Surgery is extremely effective and the problem hardly ever recurs in the treated finger or thumb, though you will have to give up work for a while. There is little risk of complications.

The surgery generally lasts for about 20 minutes and generally patients do not have to stay in the hospital for more than a day. The treatment is generally done under local anesthetic, so you will not feel any pain in your hand though awake.

There are 2 kinds of surgeries to correct trigger finger:

  • percutaneous trigger finger release surgery
  • open trigger finger release surgery

If you are suffering from rheumatoid arthritis, you will not have to go through these treatments as they may cause your finger to point sideways. In its place, a distinct procedure, a tenosynovectomy, may be recommended that includes removing part of the tendon sheath to enable the tendon to move once more.

Percutaneous Trigger Finger Release Surgery

In the of the open method of surgery, a local anesthetic is used ; however, in place of making an incision in the palm, a needle is inserted into the bottom of the affected finger. The needle is used to cut through the ligament.

This surgery does not include an incision so you will not have a wound or scar. But, the treatment is a bit more dangerous compared to open surgery and may be less useful. Vital arteries and nerves are extremely close to the tendon sheath and can be damaged. This is why open surgery is generally preferred.

Open trigger finger release surgery

In this type of surgery, a local anesthetic injection into the palm of the hand is given. Then, a little incision is made in the palm of the hand along one of the natural creases, which means that the scar will not be visible. The surgeon cuts through the tendon sheath in order to make it wider. The wound will be fastened with stitches and covered with a bandage.
