Trigger digits (also known as 'trigger finger' or 'stenosing tenosynovitis') is where the tendons catch as they glide under the tight pulleys at the front of the fingers. If the tendon has become a little thickened, it can struggle to pass under the pulley system.
Symptoms
Patients with the condition often have difficulty moving the fingers. When they make a fist, the finger often sticks in that position and it can be difficult to straighten the finger out again. It may be associated with significant discomfort at the base of the finger in the palm.
It may also be associated with other conditions such as inflammatory arthritis. It is also common in patients who have diabetes and other systemic health problems.
