Efficacy of Ultrasound-Guided Hydrodissection for Treating De Quervain's Tenosynovitis

Objective: This study evaluated the effectiveness of ultrasoundguided hydrodissection treatment for De Quervain's stenosing tenosynovitis, characterized by the narrowing of the first extensor compartment of the wrist. Notably, approximately 2% of cases involve a fibrous septum that divides the compartment. Subjects and Methods: Ninety-five patients diagnosed with De Quervain's disease using ultrasound underwent hydrodissection treatment. When a septum was present, the needle was redirected into each sub -compartment to distribute the therapeutic solution evenly and facilitate the breaking of the septum. Results: Ninety patients reported significant improvements in pain and functionality within 2 months of the initial treatment, with a marked decrease in the mean visual analog scale score from 7.65 +/- 1.31 to 1.65 +/- 2.32. A second infiltration, administered 2 months later, further alleviated pain and enhanced hand function ality. However, 5 patients with septum required surgical intervention after nonconclusive results from the infiltrative treatment. Conclusions: This study confirms that ultrasound -guided hydrodissection is an effective treatment for approximately 95% of patients with De Quervain's disease, achieving substantial pain relief and improved joint mobility after the first treatment. These findings support the continued use of ultrasound guidance to enhance the precision and efficacy of treatment in complex cases.
