概括

在部微稳定性 (MI) 中没有发现伊利奥卡普苏拉斯肌肉缩. 与其他部疾病相比,患有心脏病的患者的腹筋和腹筋 (IC+IP) 肌肉尺寸较小,这表明在预测心脏病时,IC肌肉质量的预后价值有限.

科学领域:

整形外科手术整形外科手术
部的生物力学
肌肉骨成像技术肌肉骨成像技术

背景情况:

在部边缘发育性形 (BDDH) 和部发育性形 (DDH) 中观察到伊利奥卡普苏拉斯 (IC) 肌肉缩,这表明它可能在部稳定中发挥作用.
在没有乙肌底覆盖的情况下,IC肌肉在部微稳定性 (MI) 中的作用尚不清楚.

研究的目的:

为了比较IC肌肉尺寸和脂肪透在患者的MI,BDDH,和混合类型的股骨支柱阻塞 (mFAI).
评估IC肌肉形态和部病理之间的关系.

主要方法:

在95名接受关节镜检查的患者中进行了回顾性病例控制研究 (证据水平,4).
基于侧向中心边角 (LCEA) 的分类:BDDH (18°24.9°),MI (25°39°) 和mFAI (>39°).
术前的MRI和X射线图被用来测量IC肌肉尺寸,脂肪透,以及IC和阴 (IC+IP) 联合截面面积 (CSA).

主要成果:

与BDDH和mFAI组相比,MI患者的IC肌肉深度,宽度和CSA显著较小,以及较小的IC+IPCSA (P < .05).
在IC宽度,IC CSA和IC+IP CSA测量方面,观察者之间达成了良好至优异的共识.
心脏病组的女性患者比例较高 (P = .003),但在冲击或α角的放射性标志物中没有发现显著差异.

结论:

在部微不稳定性 (MI) 组中没有观察到伊利奥卡普苏拉斯 (IC) 肌肉缩;相反,观察到较小的IC肌肉尺寸.
在预测部微稳定性方面,IC肌肉质量似乎具有有限的预后价值.
该研究提供了一种可复制的方法来测量IC肌肉形态,具有良好的观察者间协议.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
