概括

仅仅宫接口融合系统 (CIFS) 提供了宫脊椎手术的成本效益较高的替代方案,可保持运动性. 然而,仔细的患者选择至关重要,以减轻伪缩和相邻段变性等风险.

科学领域:

脊柱融合技术的生物机械分析.
在骨科手术中使用有限元建模.

背景情况:

退行性椎脊柱疾病通常涉及面部和圆盘问题,导致不稳定.
宫界面融合系统 (CIFS) 是一种手术选择,通常与前盘配对.
由于手术复杂性和风险增加,前盘与CIFS结合使用前盘的必要性仍在争论中.

研究的目的:

为了生物力学评估CIFS单独与CIFS与前盘结合的疗效.
通过有限元模型评估这些手术策略对椎脊柱稳定性和相邻部分健康的影响.

主要方法:

经过验证的C2-C7有限元模型被用于模拟三个手术场景:单独前盘,单独CIFS,以及带前盘的CIFS.
在各种负载条件下 (屈曲,延伸,轴旋转,横向曲) 在处理的平面 (C4-C5,C5-C6,C4-C6) 上进行了模拟.

主要成果:

仅CIFS就能在经过处理的水平上保持一些运动,保持运动范围在正常范围内,并在经过处理和相邻的水平上降低压力.
单独使用前盘和使用前盘的CIFS消除了运动,但在相邻的水平上增加了超移动性和内压力.
单独CIFS显示出由于残余运动而导致伪关节炎的风险更高,而其他模型则对相邻部分构成风险.

结论:

仅CIFS就为椎脊柱提供了一种具有成本效益的手术选择,可以保持生理运动.
仔细选择患者和术后康复是必要的,以最大限度地降低与CIFS相关的风险,如伪和相邻段变性.
调查结果表明,单独的CIFS可以是一个可行的替代方案,平衡稳定性和保持流动性.

Statically Indeterminate Problem Solving

Statically Indeterminate Problem Solving

Statically indeterminate problems are those where statics alone can not determine the internal forces or reactions. Consider a structure comprising two cylindrical rods made of steel and brass. These rods are joined at point B and restrained by rigid supports at points A and C. Now, the reactions at points A and C and the deflection at point B are to be determined. This rod structure is classified as statically indeterminate as the structure has more supports than are necessary for maintaining...

Stability of structures

Stability of structures

In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...
