The ring finger is often one of the fingers affected. The condition is also known as stenosing tenosynovitis. Tendons are bands of tissue that attach muscles to bones.
Trigger finger and trigger thumb are two conditions that go hand-in-hand literally. This condition, at best, is mildly irritating and, at worst, is extremely painful and debilitating. This results in many common symptoms including finger stiffness, a popping or clicking sensation, tenderness or even a visible bump at the base of your finger, and finger locking in a bent position.
These pulleys hold the tendons close to the bone. This is similar to how a line is held on a fishing rod Figure 1. Trigger finger occurs when the pulley becomes too thick, so the tendon cannot glide easily through it Figure 2.
Trigger finger or thumb arises either from thickening of the flexor tendon sheath which occurs following tenosynovitis of infective, traumatic or rheumatolgical origin or from nodular thickening of the flexor tendon itself which may be congenital. In either case, smooth passage of the tendons through their sheaths is compromised, causing symptoms of delayed and sometimes painful extension of the digit commonly the middle fingerperhaps accompanied by a cracking sound. Patients commonly report having to straighten the finger physically, which otherwise remains locked in the flexed position.
A trigger finger or thumb happens when trying to bend or straighten the finger or thumb. It locks or catches and does not move freely. In children, it is often first seen when the child is older than 1 year of age.
Trigger finger occurs due to inflammation of the tendons that flex your fingers, causing finger tenderness and pain. Advanced symptoms include a thumb, another finger, or both being locked in a bent or straight position. You may also be unable to uncurl your finger without using the other hand if you have an advanced case of trigger finger. The symptoms of trigger finger tend to be worse in the morning.
Trigger Finger is a condition affecting the tendons in the hand. It can affect one or more fingers and sometimes the thumb. Tendons are fibrous cords in the body joining bones to muscles allowing bones to move.
