- 放射学 放射学是指放射学
- 生物医学工程 生物医学工程
背景情况:
- 介质间 (IN) 对于膝关节的稳定性至关重要,它容纳了前十字带 (ACL) 等关键带.
- 在骨关节炎进展过程中IN形态的变化可能表明未来的ACL损伤风险.
- 了解这些变化对于早期预防策略至关重要.
研究的目的:
- 为了研究骨关节炎对骨间隙骨形态的影响.

主要方法:
- 利用了来自骨关节炎倡议的MRI数据,分析了五个Kellgren和Lawrence骨关节炎严重程度组中的415名随机选择的患者.
- 测量了关键参数,包括隙宽度 (NW) 和隙宽度指数 (NWI) 在冠状和轴面的形沟和关节线水平.
- 将IN形状分为A形,反向U形和 Ω形.
主要成果:
- 骨关节间口形态受到骨关节炎的显著影响, Ω 形状特别适用于严重的骨关节炎 (p < 0.001).
- 图像平面和测量水平也显著影响了测量 (p < 0.001).
结论:
- 骨关节炎的程度不断增加,导致肌间空间形态的显著变化.
- 在冠状平面的关节线上的测量提供了更可靠的IN狭窄的诊断.

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.

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...

01:07Development of the Limb Synovial Joints
1.3K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
