Clinical Scenario
A 52-year-old man with a 10-year history of poorly controlled type 2 diabetes presents to the outpatient clinic, distressed by frequent locking of his right middle finger when trying to open a fist. His symptoms have progressively worsened over the past 6 months, and he now has to manually straighten the finger when it locks. As a mechanic, this issue is interfering with his work. He denies any recent trauma or hand injuries but notes occasional mild swelling around the affected joint. His HbA1c is 8.5%.
Objectives:
1. Clinical examination of the hand.
2. Understanding the pathophysiology of trigger finger.
3. Clinical diagnosis of trigger finger.
4. Discussion of management options.
5. Understanding surgical indications and techniques.
