Trigger Finger

Trigger finger is a condition in which the finger gets stuck and entangled in a bent position. The finger bends or straightens in a snap, like pulling and releasing a trigger. The condition, also known as stenosing tenosynovitis, occurs in the form of trigger finger or trigger thumb. Children may have congenital thumb involvement. It sometimes resolves spontaneously in early infancy.

How does trigger finger occur?

Trigger finger involves structures called pulleys, which control the sliding movement of the tendons. Tendons are structures that provide movement in the form of long beams. Their sliding movement is controlled by pulleys. The pulley forms a tunnel. The tendon makes its sliding movement in this tunnel. The pulley keeps the tendon attached to the bone tissue. Pulleys act just like a pulley. Trigger finger or thumb occurs when the tendons show a nodule or swelling. When the tendon swells, it gets stuck at the tunnel entrance. Pain in the finger occurs as a jumping sensation and snagging. When the tendon gets stuck, the pain, inflammation and swelling increase even more. Thus a vicious circle is created. Sometimes it is difficult to open the stuck finger, it remains locked.

What are the symptoms?

Feeling of stiffness in the finger, especially in the morning Popping or clicking sensation when moving the finger Nodule in the palm at the level of the affected finger Sudden locking of the finger in a straight or bent position

Why does it happen?

The cause of this disease is not clear. It can also be seen with diseases such as rheumatoid arthritis, rheumatic diseases, gout and diabetes.

How is trigger finger treated?

The aim of treatment in trigger finger disorder is to eliminate the condition of snagging and locking. Thus, the movement of the finger is restored. By relieving the pain and inflammation around the flexor tendon, the tendon and sliding movement becomes easier again. To relieve the inflammation and swelling in the tendon, oral medication, injections in the area or the use of a finger splint can help. However, if these methods fail or if the disease is in an advanced stage, surgical treatment should be considered. Surgery is a one-day procedure. During surgery, the spool where the impingement is located is cut. Active finger movements start immediately after surgery. In some patients, pain, discomfort and swelling at the surgical site may last longer than in others. Hand physiotherapy is usually required for better use.
