概括
一般的关节高移动性增加了MRI上的肘部不一致性,特别是在俯卧. 然而,超移动和正常群体在延伸和发音方面存在相似性,这表明这是生理上的.
科学领域:
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 人体解剖学 解剖学 解剖学
背景情况:
- 后侧旋转不稳定性 (PLRI) 与MRI上的肘部关节不一致性有关.
- 在健康个体中,通用关节超移动性和肘部定位对肘部关节一致性的影响仍然不清楚.
研究的目的:
- 为了研究一般的超流动性和特定的肘部位置如何影响健康个体的关节一致性,使用MRI.
- 为了区分生理关节不一致与病理状况.
主要方法:
- 一项病例控制研究,涉及20名正常关节松的健康参与者和20名具有普遍超移动性的健康参与者.
- 双边肘部MRI在各种位置获得:完全伸展 (上垂/前垂) 和30°曲 (上垂/前垂).
- 放射性头关节和腰关节的相对性被定量评估在角,冠状和轴面平面.
主要成果:
- 肘部关节一致性显著增加在pronation与supination相比.
- 超移动的个体通常表现出更大的关节不一致性,除非肘部处于延伸和伸展状态.
- 冠状腰骨对应性从延伸/俯卧到伸缩和屈曲/伸缩位置得到改善.
结论:
- 健康个体的肘部关节一致性取决于位置,从俯卧增加到俯卧.
- 在伸展和伸展位置上,超移动和正常的个体表现出类似的肘部关节一致性.
- 在特定的MRI位置期间,高移动性个体的关节不一致性增加是生理上的,不应该被误诊为PLRI.

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Structural Joints: Synovial Joints
3.2K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Magnetic Resonance Imaging
4.8K
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...

Knee Joint
1.3K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Bones of the Upper Limb: Humerus
2.7K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Joints

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
