概括

内侧压力和带硬性显著影响青少年异常脊椎病 (AIS) 的进展. 较硬的带增加压力,在AIS中为脊柱生长创造了一个不平衡的机械环境.

科学领域:

生物医学工程生物医学工程
整形外科整形外科整形外科
脊柱生物力学脊柱生物力学

背景情况:

青少年异常脊椎病 (AIS) 的进展缺乏关于机械因素的共识.
关于几何不对称和AIS差异增长的现有理论有不清楚的相关性.

研究的目的:

为了研究一种假设,即肌内压力和带结构驱动AIS中不对称的脊柱生长.
探索影响AIS脊柱形的机械环境.

主要方法:

开发了一种患者特定的3D数值模型,该模型是脊椎结裂的脊柱.
模拟包括在不同的带刚性条件下分析脊柱对上肢体重的反应.
进行了四次分析:一个对照 (没有带) 和三个逐渐变硬的带.

主要成果:

在脊椎高度变形的区域内,脊柱内压力升高.
带刚度的增加直接与更高的内压力相关.
几何不对称导致对形区域的偏心压力,导致脊椎形区域的升起.

结论:

内压力和带硬之间的相互作用会造成一个不平衡的机械环境.
这种不平衡的环境,由不对称的增长和压力驱动,是AIS进步的关键因素.
这些发现强调了生物力学因素在理解和潜在地管理AIS方面发挥的关键作用.

Structural Joints: Cartilaginous Joints

Structural Joints: Cartilaginous Joints

As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
