概括

前部跨关节交叉螺丝 (ATCS) 固定提供了生物力学稳定性,而不是atlantoaxial不稳定性. 与传统的前部跨关节螺丝 (ATS) 相比,双边ATCS固定显著减少了曲延伸的运动.

科学领域:

整形外科手术整形外科手术
生物机械工程生物机械工程
脊柱融合技术脊柱融合技术

背景情况:

大西洋轴心的不稳定性带来了重大的临床挑战.
传统的前部跨关节螺丝 (ATS) 固定是一种常见的手术方法.
需要新的固定方法来提高生物力学稳定性.

研究的目的:

为了评估前部跨关节交叉螺丝 (ATCS) 固定的生物力学稳定性.
为了比较ATCS与传统ATS固定的有效性.
为ATCS在治疗大西洋轴心不稳定的临床应用提供证据.

主要方法:

测试了8个人类尸体头-C4标本.
评估了五种情况:完整,损伤 (牙骨折),ATS固定,单边ATCS固定和双边ATCS固定.
纯时刻用于测量C1-C2.2.的运动范围 (ROM) 和中性区域 (NZ).

主要成果:

与完整状态和受伤状态相比,ATS和ATCS固定都显著减少了运动 (p < 0.05).
双边ATCS固定显示,曲延伸的ROM显著低于ATS和单边ATCS (p <0.05).
在横向曲和轴旋转的固定之间以及在中立区域中,没有观察到ROM的显著差异.

结论:

前跨关节交叉螺丝 (ATCS) 固定是一种生物力学上有效的方法,用于大西洋轴心不稳定.
ATCS可以作为替代或补充的固定技术.
与ATS相比,双边ATCS在曲延伸方面提供了更高的稳定性.

Articulations of the Vertebral Column

Articulations of the Vertebral Column

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
