Intra-sheath vs Extra-sheath Injection for De Quervain's Tenosynovitis
Sponsor: University of California, Davis
Summary
The aim of the study is to determine whether or not extra-sheath steroid injections are inferior to intra-sheath steroid injections in the treatment of DeQuervain's Tenosynovitis. Patients will be randomized to either the intra-sheath group or the extra-sheath group and their pre-injection level of pain will be assessed using the visual analog scale. Appropriate injections will then be administered by 1 of 3 UC Davis hand surgeons. Six weeks post injection the patients will be reassessed using the visual analog scale and their score at 6 weeks will be compared to their pre-injection score.

Conditions
Interventions
Intra-sheath injection
Ultrasound guided corticosteroid injection composed of 1ml of 1% lidocaine and 1ml (20mg) of dexamethasone. Injection will be administered directly into the abductor pollicis longus/ extensor pollicis brevis sheath.
Extra-sheath injection
Ultrasound guided corticosteroid injection composed of 1ml of 1% lidocaine and 1ml (20mg) of dexamethasone. Injection will be administered surrounding the abductor pollicis longus/ extensor pollicis brevis sheath.
Ultrasound
To ensure accuracy of fluid deposition into the tendon sheath in the intra-sheath injection arm and outside of the tendon sheath in the extra-sheath injection arm, all injections will be performed under ultrasound guidance. The ultrasound machine used will be a portable ultrasound machine located at the UC Davis orthopaedic clinic in Sacramento
