What is the Pathophysiology of trigger finger?
The forceful compression and tensile stress from manual works, resistive flexion manners cause crushing of flexor fibrous sheath over A1 pulley or even palmar aponeurosis,
which is apart of digital pulley system and bring about accumulative damage to tendon sheath and A1 pulley,starting
From microtrauma, inflammation, swelling, thickening fibrocytes proliferation or fibrosis and cartilaginous change of A1 pulley
And thickening or contracted synovial membrane and adhesion of flexor fibrous sheath cause painful digital base ,limitation finger movements, triggering, snapping, locking and deformity progressively
Percutaneous release of A1 Pulley and flexor fibrous adhesion.
