概括

前腰椎间体融合 (ALIF) 和阴茎固定在成人脊椎形的长段融合过程中减少L5-S1结处的应力. 同时使用并没有显示出显著的额外生物力学益处.

科学领域:

脊柱生物力学脊柱生物力学
整形外科手术整形外科手术
成年人的脊柱形

背景情况:

成年脊柱形 (ASD) 的长段融合具有很高的伪关节炎率,可能是由于腰部神经节 (LSJ) 机械力.
在L5-S1和阴茎固定处的身体间是减少LSJ应变的策略.
本综述考察了与ASD长段融合中的仪器相关的LSJ生物力学.

研究的目的:

在成年脊椎形 (ASD) 中长段融合仪器的仪器背景下,评估目前关于腰部神经结 (LSJ) 生物力学的文献.

主要方法:

对MEDLINE (PubMed) 和EMBASE数据库进行系统审查.
包括涉及L5-S1.1.多层脊柱融合的人体尸体研究.
包括测量带有和没有阴茎固定和L5-S1身体间固定的生物力学差异的研究.

主要成果:

与单独的脚螺丝相比,前腰间体融合 (ALIF) 和阴固定也同样减少了L5-S1运动范围 (ROM) 和S1螺丝应变.
阴茎固定减少了更多方向的螺丝拉伸,但增加了后杆拉伸.
结合ALIF和阴茎固定时没有发现显著的生物力学差异,尽管在一些研究中发现了下降L5-S1ROM的趋势.

结论:

阴茎固定和ALIF子都减少了LSJ多层融合结构中的S1螺丝拉伸和L5-S1ROM.
目前的生物力学证据不支持并发阴固定和ALIF子的显著额外益处.
需要进一步的生物力学和临床研究来澄清这些策略与成功的LSJ关节切除之间的关系.

Structural Joints: Fibrous Joints

Structural Joints: Fibrous Joints

Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

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 or...

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...
