If you frequently find yourself wondering, “Why do my fingers lock up?” then you may be a part of the population suffering from a case of Trigger Finger, also known as Stenosing Tenosynovitis. This is a condition that affects the hands and fingers, causing the affected finger to bend or straighten suddenly and often get stuck in a bent position. Keep reading to learn more about Stenosing Tenosynovitis.
Causes & Symptoms
Before we can understand the cause of Trigger Finger, we must understand the function of tendons. Your hands are filled with tendons, fibrous cords that attach bone to muscle and aid in movement; the type of tendon that connects the bones and muscles of the fingers or thumb to the forearm is called a Flexor Tendon. These tendons are surrounded by a protective layer of tissue called the “tendon sheath”.
Trigger Finger happens when the tendon sheath becomes inflamed, causing abnormal resistance that restricts the natural movement of the tendons. Trigger finger can affect any finger on the hand, including the thumb, and may involve multiple fingers at a time. In some cases, both hands can be affected at once. Symptoms of Trigger Finger include:
- Finger stiffness
- Popping or clicking of the finger joint
- Tenderness or nodules at the based of the affected finger
- Fingers locked in a bent position and suddenly popping straight
- Fingers locked in a bent position that cannot be straightened
Risks & Prognosis
Some are more likely to develop Trigger Finger than others, so it is important to know the factors that put you more at risk for the disease. You may be at a higher risk of developing Trigger Finger if you:
- Work at a job or hobby that requires repetitive hand use or prolonged gripping.
- Suffer from certain medical conditions, such as Diabetes or Rheumatoid Arthritis.
- Are a woman, as Trigger Finger is more common in the female sex.
- Have recently had surgery for Carpal Tunnel Syndrome. (Trigger Finger can be a complication following surgery.)
- Are over the age of 40.
It is important to note that Trigger Finger rarely leads to any serious complications if left untreated. However, the condition causes pain and limited mobility, which can subtract from your overall quality of life. Additionally, the condition may become more severe over time.
Treatment Options
There are many treatment options for Trigger Finger that can improve and manage symptoms; which treatment you elect to pursue depends largely on the severity of your condition.
Some doctors may suggest anti-inflammatory drugs to help with minor swelling. Rest, wearing a splint, and stretching your hands may also help in reducing inflammation. However, for more severe cases, your doctor may recommend steroid injections to reduce inflammation or surgical treatment to address the constricted segments of the tendons in your hand.
