The problem with trigger finger happens when the finger, during finger movement, catches in a bentposition. The following text will talk about this problem in detail. The problem whose name is self-explanatory, occurs when we try to grip somethingor close the fist, but it can also happen in different situations. It can occurwhen we are opening the fist. The people with this problem experience pain andhear clicking sound when they try to open or close the fist. Normally, theopening and closing would be smooth and should not cause any pain. The fingerscan be stuck in one position, motionless, but this happens in most seriouscases. The problems that the trigger finger produces usually affect the indexand ring finger, but it can also cause problems for the thumb. Mostly, only onefinger is affected but sometimes it can affect the several fingers.
Tendons connect muscles and the bones of the fingers. They are inelastic tissuesthat are located in the fingers and they connect bones of the finger with theforearm muscles. The bending of the fingers is made possible with the help ofthese tendons. Tendon sheaths are tubes that are found around the tendons, andthey are responsible for creation of tensoynovium, which is responsible forlubricating the tendon. With the effect of this lubricant, the movement issmooth and the fingers easily can be straightened or closed. The problem we aretalking about in this text occurs when the tendons become scarred, inflamed orirritated. There is no lubrication and this causes the sound we have mentioned.This can also lead to the narrowing of the tendon sheaths. Many causes cab takeblame for the creation of trigger finger. Some of them are diabetes, gout,rheumatoid arthritis and several inflammatory diseases. This problem, which isseen mostly among women between 40 and 60 years of age, can be caused by someinfection, amyloidosis or hypothyroidism.
