Definition/Description[edit | edit source]
Trigger finger is a common condition that is thought to be caused by inflammation and subsequent narrowing of the A1 pulley. This can cause pain, clicking, catching, and loss of motion, especially into flexion, of the affected finger.[1]
Epidemiology/Etiology[edit | edit source]

Characteristics/Clinical Presentation[edit | edit source]
Trigger finger can have a range of clinical presentations. Initially the patient may present with painless clicking with movement of the digit. This can progress to painful catching or popping typically at the MCP or PIP joints, stiffness and swelling especially in the morning, loss of full flexion/extension, palpable painful nodule, and/or finger locked into a flexed position.
Differential Diagnosis[edit | edit source]
The main characteristic of trigger finger is a popping and/or catching with movement of the digit, especially in flexion to extension. However, this is not a unique characteristic to trigger finger. Other etiologies associated with a locking digits can include:
