概括

与健康个体相比,患有侧面乳头位移 (LPD) 的患者的斜面大脑 (VMO) 肌肉大小较小. 这表明减少VMO肌肉质量和状骨不稳定性之间存在联系.

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.
运动医学运动医学

背景情况:

骨骨架不稳定 (PFI) 是一种常见的骨科疾病.
在PFI中,大中斜体 (VMO) 的作用尚未完全理解.
调查VMO横截面区域 (CSA) 可以提供有关PFI机制的见解.

研究的目的:

确定VMO CSA与一次性和反复的侧面部脱位 (LPD) 病例中的骨骨部不稳定 (PFI) 之间的关系.
在PFI患者中,探索VMO CSA和三角膜发育不良症,骨结核位置和骨高度之间的关联.

主要方法:

从90名初级LPD,90名复发LPD和56名对照患者的MRI扫描进行了回顾性分析.
对整个大腿的VMO CSA比率的计算.
使用Dejour协议测量结节-喉沟 (TT-TG) 距离,骨倾斜角 (PTA),喉角 (TSA) 和Insall-Salvati比率 (ISR).

主要成果:

与对照组相比,原发性和复发性LPD患者的VMO CSA比率明显较低 (P <0.05).
再发性LPD患者的TT-TG距离和PTA远远大于初级LPD患者 (分别为p = 0.0101和p = 0.0071).
在LPD组中,没有发现Dejour协议参数和VMO CSA比率之间的显著相关性.

结论:

减少的VMO肌肉大小与初级和复发的侧面带位移有关.
虽然VMO大小似乎与带脱有关,但从这项研究中无法确定因果关系.
需要进一步的研究来澄清VMO在PFI中的病因作用.

关键词:

侧面的皮带位脱位.这就是为什么MRI是MRI.脊椎骨骨的不稳定性在VMO VMO

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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
