摘要
目的：扳机指是手指疼痛和触发的主要原因之一。屈肌腱被称为环形滑轮的纤维带固定。第一个环形滑轮（A1滑轮）位于掌指关节水平。扳机指的特点是A1滑轮增厚。缺乏临床和超声检查的危险因素，可以帮助临床医生。本研究的主要目的是测量触发指患者与健康志愿者的屈肌腱和A1滑轮的厚度，揭示触发指的危险因素。方法：研究对象为30名健康志愿者和30名扳机指患者。超声测量屈肌腱和A1滑轮的厚度。并进行多元回归分析。结果：健康组屈曲肌腱和A1滑轮的平均厚度分别为3.21±0.64 mm和0.40±0.09 mm。TF组屈指肌腱和A1滑轮的平均厚度分别为3.78±0.86 mm和0.49±0.16 mm。差异有统计学意义（p = 0.010、p = 0.009）。触发指患者屈肌腱和A1滑轮的平均厚度均显著高于邻指和对侧健康指（p = 0.001, p = 0.001, p = 0.019, p = 0.002）。糖尿病患者发生扳机指的风险是糖尿病患者的11.5倍，有强迫手病史的患者发生扳机指的风险是糖尿病患者的3.734倍，屈肌腱厚度每增加1 mm增加2.912倍，A1滑轮厚度每增加0.1 mm增加1.724倍。结论：本研究发现，与对照组相比，扳机指组的屈肌腱和A1滑轮增厚。糖尿病、手部强迫史、肌腱增加和A1滑轮厚度是诱发指的危险因素。试验注册：扳机指超声特征，注册号：NCT05675488。
Comparison of Ultrasonographic Features Among Healthy Individuals and Patients With Trigger Finger.
Purpose: The trigger finger is one of the leading causes of finger pain and triggering. The flexor tendons are stabilized by a fibrous band called the annular pulley. The first annular pulley (A1 pulley) is located at the level of the metacarpophalangeal joint. Trigger finger is characterized by thickening of the A1 pulley. There is a lack of clinical and ultrasonographic risk factors that may help clinicians. The main purpose of the study was to measure the thickness of the flexor tendon and A1 pulley in patients with trigger finger compared to healthy volunteers and to reveal risk factors of trigger finger.
Methods: The study included 30 healthy volunteers and 30 patients with trigger fingers. The thickness of the flexor tendon and A1 pulley were measured using ultrasound. Multiple regression analysis was also conducted.
Results: In the healthy group, the mean thickness of the flexor tendon and A1 pulley were 3.21 ± 0.64 and 0.40 ± 0.09 mm, respectively. In the TF group, the mean thickness of the flexor tendon and A1 pulley were 3.78 ± 0.86 and 0.49 ± 0.16 mm, respectively. The differences were statistically significant (p = 0.010 and p = 0.009, respectively). The mean thickness of the flexor tendon and A1 pulley of trigger finger were significantly higher than adjacent and contralateral healthy digits of the patients with trigger finger (p = 0.001, p = 0.001, p = 0.019, p = 0.002, respectively). The risk of trigger finger was found to be 11.5 times higher in diabetic patients, 3.734 times higher in patients with a history of hand forcing, 2.912 times with a 1 mm increase in flexor tendon thickness, and 1.724 times with an increase of 0.1 mm in A1 pulley thickness.
Conclusions: In this study, the flexor tendon and A1 pulley were found to be more thickened in the trigger finger group compared to the controls. Diabetes mellitus, history of hand forcing, increased tendon, and A1 pulley thickness are among the risk factors associated with trigger finger.

期刊介绍：
The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography.
The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents.
JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
