This condition is caused by chronic inflammation of the flexor tendons of the fingers. A single finger or multiple fingers can be affected. As a result of the inflammation the tendon and tendon sheath can become scarred resulting in an impediment for the tendon to glide through the sheath.
The symptoms that result are pain in the palm and fingers and/ or 'locking' or 'triggering' of the digits. Initial treatment is typically an oral anti-inflammatory medication, steroid injection and splinting. In cases that persist surgical correction is recommended.
