Ultrasonography (US)-guided steroid injections can improve the accuracy of injection in patients with de Quervain disease, especially in those with an intracompartmental septum. Although the main lesion of de Quervain disease in patients with a septum is a stenosing tenosynovitis of the extensor pollicis brevis (EPB), no report we know of has compared injection into the EPB subcompartment with an injection into both the abductor pollicis longus (APL) and EPB subcompartments. In this randomized trial, we compared the results of US-guided steroid injections targeting both subcompartments and the EPB subcompartment alone in patients with de Quervain disease.

对于 de Quervain 病患者，在两个室中注射类固醇是否比单独在拇短伸肌亚室中注射更有效？随机对照试验。

超声检查 (US) 引导下的类固醇注射可以提高 de Quervain 病患者的注射准确性，尤其是房间隔内的患者。尽管隔膜患者的 de Quervain 病的主要病变是拇短伸肌 (EPB) 的狭窄性腱鞘炎，但据我们所知，没有报告比较过 EPB 亚室注射与拇长展肌 (APL) 注射和 EPB 子隔间。在这项随机试验中，我们比较了美国引导下针对 de Quervain 病患者的两个亚区和单独 EPB 亚区的类固醇注射结果。
