Finger entanglement can occur due to inflammation of the tendons that move the fingers. Medically, this condition is called “trigger finger”. It causes complaints such as getting stuck in the fingers, difficulty in bending and opening, pain and tenderness in the part of the inflammation (inflammation).
What Causes Finger Sting?
One end of the tendon fibers in our hands is attached to the finger bones and the other end is attached to the muscles that provide movement. More precisely, tendons are extensions where the muscles that provide movement are attached to the bones. When the muscles contract, the tendons pull the bone and move it.
Along the wrist and the inner surface of the hand are tendons that allow the fingers to be bent; These are called flexor tendons. Tendons are found in tunnel-shaped sheaths. When the tendon sheaths narrow, it becomes difficult for the tendon to slide. As the tendon moves in the narrowed sheath, it is damaged and edematous over time. In this case, it becomes more difficult to move the finger. A nodule may form on the tendon due to the inflammatory reaction. The person may not be able to open his finger, his finger remains bent in general, he needs help from the other hand when he wants to open it. Or the finger can suddenly be opened by force; This is why the problem is called trigger finger.
Who Gets Trigger Finger?
It is more common in people aged 40-60 years. Frequent hand movements such as diabetes, goiter (hypothyroidism), rheumatoid arthritis, playing musical instruments are risk factors.
What Are Trigger Finger Symptoms?
Persistent pain at the base of the thumb or another finger, a hard swelling (nodule) in the palm near the root of the finger, tenderness to touch in this area, a crackling or massing sound with the movement of the finger, entanglement or stiffness of the finger. Trigger finger may progress and worsen over time if it is neglected in the first periods. In the advanced stage, the finger may remain fully bent and cannot be opened at all. Symptoms associated with trigger finger are usually worst in the morning, easing as they move and warm up.
How Is It Treated?
It may be beneficial to take a break from repetitive movements that force the finger for 1-1.5 months and rest. A splint or splint can be used to support the finger and wrist. Cold application can be applied to reduce swelling. Warming may also be helpful, if appropriate. Soaking the hand in hot water several times a day allows the tendons and muscles to relax. His movements can be opened by gently stretching the fingers. Some pain relievers also have anti-inflammatory effects. These drugs can be used for short periods of time. Another treatment option is to inject a corticosteroid-containing injection into the nodule. If there is no improvement with these, surgeries in which the narrowed tendon sheath is loosened come to the fore.
