Also known as stenosing tenosynovitis, trigger finger is a condition when one of your fingers is locked in a bent position, limiting your movement and resulting in pain, as well as, tenderness.
The muscles and bones in your body are connected by tendons – when your muscle is tightened, it pulls on the tendon, causing the bones to move. In a healthy finger, your tendons are able to glide easily through a small, protective sheath whenever you bend or move your fingers.
Trigger finger happens when the protective sheath becomes narrow, causing a constriction around the tendon and making it difficult for the tendon to glide through easily. The increased resistance results in the tendon becoming irritated and swollen. The inflammation of the tendon may result in a bump or nodule forming, making it more difficult for the finger to straighten, thus restricting further movement. Since the condition can hinder your daily activities, it is important to seek trigger finger treatment in Singapore as early as possible.
Factors that put you at higher risk of developing trigger finger are:
- Repeated Gripping
Certain jobs and hobbies, or performing actions that involve repetitive hand use and prolonged gripping such as texting may increase your risk of trigger finger.
- Medical Conditions
Some trigger fingers are associated with conditions such as diabetes, rheumatoid arthritis or hypothyroidism.
Signs And Symptoms
Symptoms of trigger finger often include soreness at the base or lowest joint of the finger. A nodule can sometimes be felt near the base of your finger, near your palm. Some patients may experience a painful clicking or snapping sensation when flexing the finger. They may also have difficulty trying to bend or straighten the finger. The symptoms of the trigger finger tend to be worse in the mornings, but as the day goes, the finger will start to relax more, making movement easier.
Trigger finger treatment is crucial even in the early stages of the condition. If left untreated, the trigger finger can worsen and may sometimes result in another finger becoming locked in a bent or straight position. In severe cases, patients may be unable to straighten or bend the affected fingers without the help of the other hand.
Trigger finger treatment is dependent on the severity of symptoms. Nonsteroidal anti-inflammatory drugs (NSAIDs) and wearing of splints may relieve swelling around the protective sheath and tendon to allow for smooth gliding.
Another treatment option includes an injection of a steroid medication near or into the tendon sheath to reduce inflammation at the site, allowing the tendon to glide smoothly and freely again.
If non-surgical forms of trigger finger treatment do not provide any relief, then your doctor may recommend going for surgery. A small incision is made at the base of the finger to open the protective sheath, expanding the protective sheath so that the tendon can glide more freely. This surgery is performed with local anaesthesia and patients are often discharged home on the same day of the procedure. Post-operative pain is minimal in most patients, and active movement on the finger is encouraged.
