概括
一个平坦的关节突出 (AE) 倾斜与关节 (TMJ) 减小的盘位移 (DDwR) 有关. 这表明AE平整可能是退行性重塑的结果,有助于早期的关节障碍诊断.
科学领域:
- 牙科 牙科是指牙科的专业.
- 放射学 放射学是一门学科.
- 矯正牙科 矯正牙科是一種矯正牙科.
背景情况:
- 减少的关节 (TMJ) 盘位移 (DDwR) 是一种常见的关节内疾病.
- 关节突起 (AE) 和下沟 (MF) 和DDwR之间的形态关系需要进一步调查.
研究的目的:
- 调查AE和MF形态与DDwR的存在之间的联系.
- 评估形光束计算机断层扫描 (CBCT) 在评估关节内部乱中的诊断效用.
主要方法:
- 从30名患者中对60名TMJ进行了回顾性横截面研究.
- 磁共振成像 (MRI) 将关节分类为DDwR或正常.
- 使用CBCT进行AE倾斜,高度,宽度和MF宽度的形态测量.
主要成果:
- 在研究的关节中,MRI在83.3%的关节中发现了DDwR.
- 在DDwR关节中,与正常关节相比,观察到明显较低的AE倾斜 (顶部屋顶和最适合的直线角度).
- 两组之间在AE高度,AE宽度或MF宽度上没有发现显著差异.
结论:
- 平面AE倾斜与DDwR显著相关,与传统观点相反.
- AE平整可能代表由于退行性重塑而导致的次要变化.
- 基于CBCT的AE倾向评估可以帮助评估关节内的风险和早期诊断.

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.

Structural Classification of Joints

Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
