概括

儿科触发指手术涉及A1滑轮释放使 flexor pollicis longus肌尺寸正常化. 超声波显示,手术后肌形状恢复到典型的大小,这表明空间问题可能导致触发指.

科学领域:

整形外科手术整形外科手术
儿科手术手术儿科手术手术
肌肉骨超声波扫描肌肉骨超声波扫描

背景情况:

儿科触发指是一种常见的疾病,影响 flexor pollicis longus (FPL) 肌.
确切的病因尚不清楚,但人们怀疑A1轮周围的解剖学变异.
了解手术后肌变化对于评估治疗有效性至关重要.

研究的目的:

在儿科触发指中,在A1轮释放后,研究曲器长 (FPL) 肌的尺寸变化.
为了比较手术前和手术后的肌测量,使用超声波.
探索肌形态与A1滑轮空间之间的关系.

主要方法:

超声波用于测量FPL肌的背部-手掌 (DP) 直径,放射 (RU) 直径和横截面积 (CSA).
在两个位置进行测量:近距离A1轮和A1轮下方.
在手术前1个月和手术后3个月内评估了30名患有单边触发指的儿科患者.

主要成果:

在A1轮释放后,FPL靠近A1轮的DP直径,RU直径和CSA显著减少.
在A1轮下方的FPL的RU直径和CSA在手术后显著增加.
这些变化表明,未受影响的大指的典型肌形状正在恢复.

结论:

儿科触发指的A1滑轮释放导致FPL肌尺寸的显著和有利的变化.
肌形态的正常化表明,A1轮周围的空间在触发指发育中起着关键作用.
A1轮空间的开发不足可能是导致儿科触发指的因素.

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...
