OBJECTIVE To compare the clinical effectiveness of ultrasound-guided corticosteroid injection with and without needle release of the A1 pulley in treating trigger finger. METHODS A total of 60 patients with trigger finger were enrolled in this retrospective study. Among them, 30 patients were treated with ultrasound-guided needle release of the A1 pulley with corticosteroid injection (group A) and 30 patients were treated with single ultrasound-guided corticosteroids injection (group B). The following parameters were evaluated including clinical parameters (pain degree, function of joint, finger tendon function, postoperative satisfaction), and ultrasound parameter (thickness of A1 pulley). RESULTS The postoperative visual analogue scale (VAS) and Quinnell scores in two groups were significantly lower than that before operation (p < 0.05). The postoperative Quinnell score of group A was significantly lower than that in group B (p < 0.05). The TAM results showed that the postoperative overall excellent and good rate of group A was significantly higher than that in group B (p < 0.05). The postoperative survey showed that more than 80% patients reported satisfaction in the two groups. The ultrasound imaging results showed that the postoperative thickness of A1 pulley in two groups were thinner than that before operation (p < 0.05). There were no adverse effects and complications in the two groups. CONCLUSIONS Both approaches had treatment benefit in trigger finger. Ultrasound-guided needle release of the A1 pulley with corticosteroid injection had better treatment benefits than single ultrasound-guided corticosteroids injection in improving finger tendon function and joint function.

超声引导下皮质类固醇注射有和没有 A1 滑轮针释放治疗扳机指的临床疗效比较。

目的比较超声引导下A1滑轮松针和不松针皮质类固醇注射治疗扳机指的临床疗效。方法 共有 60 名扳机指患者参加了这项回顾性研究。其中，超声引导下A1滑轮松针联合皮质类固醇注射30例（A组），30例超声引导下单次皮质类固醇注射（B组）。评估以下参数，包括临床参数（疼痛程度、关节功能、手指肌腱功能、术后满意度）和超声参数（A1 滑轮的厚度）。结果两组术后视觉模拟评分（VAS）和Quinnell评分均显着低于术前（p < 0.05）。A组术后Quinnell评分明显低于B组（p<0.05）。TAM结果显示，A组术后总体优良率明显高于B组（P<0.05）。术后调查显示，两组患者满意度均超过80%。超声影像结果显示，两组术后A1滑轮厚度均较术前变薄（p < 0.05）。两组均无不良反应及并发症发生。结论 两种方法对扳机指都有治疗益处。
