概括
肘后侧带 (UCL) 重建MRI通常在 flexor pronator 质量中显示高信号. 这一发现与palmaris longus移植收获有关,而不是肌肉紧张或其他问题.
科学领域:
- 整形外科手术 整形外科手术
- 放射学 放射学是一门学科.
- 肌肉骨成像系统的成像
背景情况:
- 柔体前体质中的焦点高信号是在肘部侧带 (UCL) 重建后的MRI上常见的发现.
- 这种术后信号异常的原因在医学文献中尚未得到充分证实.
研究的目的:
- 在肘部UCL重建后的MRI上观察到 flexor pronator质量中观察到的焦点高信号的病因.
- 为了确定是否palmaris longus移植收获是这种高信号的原因,而不是肌肉张力或肌肉变质.
主要方法:
- 对2012年至2022年期间接受UCL重建的患者进行了肘部MRI扫描的回顾性审查.
- 分析了手术笔记,以确定用于UCL重建的移植类型.
- 放射科医生评估了MRI图像的焦点高信号在 flexor pronator 质量.
主要成果:
- 在29名符合条件的患者中,17名患者接受了ipsilateral palmaris longus移植收获以进行UCL重建.
- 百分之百的患者与一个ipsilateral palmaris longus移植显示焦点胀在 flexor pronator 质量.
- 没有一个没有收获手掌长移植的患者表现出这种焦点.
结论:
- 在肘部UCL重建后,在 flexor pronator质量中观察到的焦点高信号主要与palmaris longus移植收获有关.
- 这一发现不同于由肌肉疲劳,脱落或创伤引起的.

Bones of the Upper Limb: Ulna
2.3K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Muscles that Move the Forearm
1.7K
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...
