Trigger finger is a painful and uncomfortable condition that causes a feeling of locking, or catching, when bending or straightening the finger. The finger may get stuck in a bent position, or bend/straighten with a snapping sensation. If more severe, the finger can get stuck in the bent position. This condition is also known as “stenosing tenosynovitis”.
Tendons are tough bands of fibrous tissue, which connect muscle to bone, and are enveloped in protective sheaths. Trigger finger occurs when a finger’s tendon sheath is irritated. This makes it more difficult for the tendon to glide smoothly through the sheath. It disrupts the function of the finger, as it bends and straightens.
Long-term swelling of the tendon sheath can lead to scarring and thickening, which can further affect the motion of the tendon. Over time, the tendon itself may become swollen. The snapping sensation may then occur, as the swollen tendon passes through the narrowed sheath.
Trigger finger is known to occur from repeated or forceful movements of the fingers. Medical conditions, such as diabetes and rheumatoid arthritis can also increase your risk for developing the condition.
In most cases, trigger finger can be treated non-surgically. Resting the hand, and avoiding activities that may aggravate the condition is a good first step. It is important to speak with an appropriate health care practitioner, such as a physiotherapist, to be guided in the exercises that can help decreases stiffness, and increase range of motion in the finger. Check out Therapia for video-based appointments to get advice for your condition.
Splinting is an excellent way to keep the affected finger in an extended position. This allows the tendon to heal and can reduce inflammation. The Oval 8 finger splint is comfortable, low profile, and convenient. It can be worn during the day for support, and at nighttime to keep the finger outstretched – limiting the possibility of getting stuck in the bent position.
