Trigger Finger (Stenosing Tenosynovitis): Symptoms, Causes & Treatment #2024238 (License: Personal Use)

This anatomical illustration depicts the hallmark features of trigger finger, where the flexor tendon becomes inflamed and thickened, forming a nodule that catches within the tendon sheath-particularly at the A1 pulley-resulting in finger locking or snapping. The image highlights the swollen tendon and the resultant fixed flexion deformity of the proximal phalanx. Such diagrams are commonly used in orthopedic and hand therapy education to explain pathophysiology and guide patient counseling.

Used on medical websites, patient education portals, orthopedic clinic pages, and physical therapy resources to visually explain trigger finger. Matches user intent for understanding symptoms, self-assessment, or preparing for consultation.
