Question

question 22 (mandatory) (1 point) with a trigger finger, which pulley is classically affected? a1 a2 a3 a4

Explanation:

Trigger finger is a condition where the flexor tendon gets stuck as it passes through the pulley system. The A1 pulley is located at the level of the metacarpophalangeal joint. When it thickens or becomes fibrotic, it can cause the triggering phenomenon. The A2 and A4 pulleys are more involved in maintaining the position of the flexor tendons during finger movement rather than being the primary site for trigger finger. The A3 pulley is less commonly associated with trigger finger compared to the A1 pulley.

Answer:

A. A1
