Dequervains Tenosynovitis Flashcards
1
Q
ESSENCE
A
Swelling and inflammation of the tendon sheaths in the wrist
Type of repetative strain injury
2
Q
What tendons are usually affected
A
- Abductor pollicis longus tendon
- Extensor pollicis brevis tendon
3
Q
AETIOLOGY
Pathophysiology
A
- Tendon sheath surrounds tendons, formed by connective tissue (synovial membrane), helping to lubricate and protect movement of tendons
- Extensor retiniculum is fibrous band wrapping around dorsal side of wrist. APL and EPB pass underneath this
- Repetative movement of these tendons result in inflammation and welling of tendon sheaths

Q
What is Finkelsteins test
A
- Patient rests forearm on surface in neutral position with wrist hanging off and unsupported
