Trigger Finger

Trigger Finger

TRIGGER FINGER
It is also referred to as stenosing tenosynovitis. It appears as a trigger finger or trigger thumb. Children can have congenital thumb involvement. There is sometimes spontaneous recovery in early infancy. It employs components known as pulleys to control the sliding movement of tendons. Tendons are lengthy beam-like structures that facilitate mobility. Pulleys govern their sliding movement. The pulley creates a tunnel.The tendon makes its sliding movement in this tunnel. The pulley ensures that the tendon remains attached to the bone tissue. Pulleys act like a pulley. Trigger finger / thumb occurs when the tendons show a nodule (stiffness - thickening) 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 cycle occurs. Sometimes it is difficult to open the stuck finger, it remains locked.

How does it occur?

It is unclear what causes this disease. It can be seen in conditions such as rheumatoid arthritis, gout, and type 2 diabetes (diabetes).

How is it treated?
The treatment's goal is to eradicate the snagging and locking problem. As a result, the finger's movement is restored. The tendon and sliding action are made easier by decreasing the discomfort and inflammation around the flexor tendon. Oral medication, injections in the area, or the use of a finger splint can help alleviate tendon irritation and swelling. If these treatments fail, surgical intervention 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 may be required, usually for better use.
