Nonsurgical Treatment of De Quervain Tenosynovitis: A Prospective Randomized Trial

Background: De Quervain tenosynovitis is commonly seen in patients who perform repetitive wrist ulnar deviation with thumb abduction and extension. Previous studies comparing nonsurgical options have contributed to a lack of consensus about ideal management. This study's purpose was to analyze results in prospectively randomized patients treated with either corticosteroid injection (CSI) alone versus CSI with immobilization. Methods: Radial sided wrist pain, first dorsal compartment tenderness, and positive Finkelstein test were used to define De Quervain. Pain score of 4 or higher on a visual analog scale (VAS) was utilized for inclusion. Following exclusion criteria, patients underwent randomization into groups: (1) CSI alone; or (2) CSI with 3 weeks of immobilization. We followed at 3 weeks and 6 months for further evaluation, where resolution of symptoms and improvements in VAS and Disabilities of the Arm, Shoulder, and Hand (DASH) scores were assessed to evaluate treatment success. Results: Nine patients with CSI alone and 11 patients with CSI and immobilization were followed. At 6 months in both groups, patients experienced significant improvement in VAS and DASH scores, while 88% of patients with CSI alone and 73% of patients with CSI and immobilization experienced complete resolution of at least 2 out of 3 of their pretreatment symptoms. Between groups, outcomes were comparable except for resolution of radial-sided wrist pain, which was superior in patients with CSI alone (100% vs 64%). Conclusions: Immobilization following injection increases costs, may hinder activities of daily living, and did not contribute to improved patient outcomes in this study. Further prospective studies are warranted.
