Stenosing tenosynovitis of the flexor tendon sheath in the right thumb, causing catching or locking.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with a history of progressive pain and mechanical locking of the right thumb. Symptoms include morning stiffness, a palpable "popping" sensation during flexion/extension, and localized tenderness at the A1 pulley. No history of acute trauma.

Clinical Examination Findings

Right thumb examination reveals a palpable, tender nodule at the level of the metacarpophalangeal (MCP) joint. Active range of motion is limited by a reproducible triggering event. No signs of infection, erythema, or distal neurovascular deficit. Finkelstein test negative.

Treatment Protocol

Conservative management initiated: activity modification, splinting of the right thumb in extension, and a course of NSAIDs. Corticosteroid injection into the A1 pulley sheath discussed as the next line of treatment if symptoms persist.
