For some people, the fingers or thumb of a hand can become locked in a bent position because there is a problem with the flexor tendon of the given finger or thumb. This is a condition that is commonly known as trigger finger, also referred to as Stenosing Tenosynovitis. When the tendon becomes inflamed or swollen, its movement through the tendon sheath may be inhibited, which can cause it to catch in the sheath.

• It can cause pain,
• Difficulty with bending or straightening the finger,
• Stiffness,
• Clicking of the tendon during movement,
• And, it can result in the finger locking in place near the hand.

The exact cause of trigger finger is not completely understood, but some risk factors have been identified. Chronic conditions like rheumatoid arthritis and diabetes have been associated with trigger finger, it is more common among people over 40, and it is more common among women than men. Overuse is not considered a risk factor for trigger finger, but it can aggravate the pain and other symptoms of the condition. Trigger Finger can occur as the result of an injury.

For many people, trigger finger will get better without treatment, but there are some cases where medical intervention is necessary. The most common recommendation for trigger finger is simple rest and to reduce the inflammation. In addition to that, a doctor may recommend a splint to keep the finger straight while the tendon heals.

Another option is a percutaneous procedure to release the affected tendon with a needle. For more severe cases, the doctor may decide to try an invasive surgical procedure to decompress the tendon by widening the canal through which it travels.
