We aimed to investigate the relationship between the pulley-tendon complexes and the severity of trigger finger. The thickness of the A1 and A2 pulleys, and the cross-sectional area of the flexor tendon under the pulleys, were prospectively assessed using 17 MHz high-resolution ultrasonography, in 20 patients with trigger finger (31 fingers). A control group comprised 15 asymptomatic fingers. The thickness of the A1 pulley and the proximal part of the A2 pulley, and the cross-sectional area of the flexor tendon under the A2 pulley, were significantly increased in the patient group. Clinical grade was significantly correlated with the thickness of the A1 pulley, the thickness of the proximal part of the A2 pulley, and the cross-sectional area of the flexor tendon under the proximal part of the A2 pulley. This study confirmed that the thickness of the A2 pulley and flexor tendon under the A2 pulley seems to be related to the severity of trigger finger.
Level III.
我们旨在研究滑车 - 肌腱复合体与扳机指严重程度之间的关系。使用17MHz高分辨率超声前瞻性评估了20例扳机指患者（31根手指）的A1和A2滑车厚度以及滑车下方屈肌腱的横截面积。对照组包括15根无症状手指。患者组中A1滑车和A2滑车近端部分的厚度以及A2滑车下方屈肌腱的横截面积显著增加。临床分级与A1滑车厚度、A2滑车近端部分厚度以及A2滑车近端部分下方屈肌腱的横截面积显著相关。本研究证实，A2滑车厚度及A2滑车下方的屈肌腱似乎与扳机指的严重程度有关。
