整形外科的研究研究.
退行性脊柱疾病是一种退行性脊柱疾病.

背景情况:

腰椎脊椎解剖与脊椎解剖和椎间盘退化有关.
帕斯缺陷对骨相邻脊柱段的影响尚不清楚.

研究的目的:

为了量化L5/S1和L4/L5的动力学和接触力学变化,由于L5部分缺陷.
调查腰椎脊髓解剖对邻近脊柱段的生物力学影响.

主要方法:

在体外对人类腰部尸体样本 (L1-S2) 进行生物力学测试.
在多个平面 (屈曲-延伸,横向曲,轴向旋转) 中应用纯矩负荷 (4Nm).
使用光学运动跟踪和压力传感器与模拟的L5双边脊椎解剖模型进行完整样本的比较.

主要成果:

脊椎解剖显著增加了L5/S1在横向曲和轴旋转中的移动性.
在所有平面 (屈曲-延伸,横向曲,轴旋转) 中,在骨L4/L5段观察到运动增加.
在L4/L5盘接触参数 (压力,面积,力) 中没有发现显著变化.

结论:

在L5的缺陷诱导在相邻的头骨段 (L4 / L5) 的细分超流动性.
在相邻部分的这种诱导过度移动性可能会导致加速的磁盘退化.
了解这些生物力学变化对于管理脊髓解剖和预防相邻细分体疾病至关重要.

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...
