Background
- Tenosynovitis of the flexor sheath of the finger or thumb as a result of repetitive use
- Also known as stenosing tenosynovitis
- Associated with:
- Diabetes
- Rheumatoid arthritis
- Amyloidosis
- Repetitive strain
- "Texting tendonitis"
Clinical Features
- Delayed, painful extension of digit
- Most commonly ring finger
- Finger clicking
- Palpable fibrous nodule
- Tenderness at A1 pulley (distal palm)
- Patients need to manually straighten finger with other hand
- Contrast with Dupuytren’s contracture, which is not usually associated with pain or history of repetitive overuse
