概括
关节直线收角 (JLCA) 随着膝关节骨关节炎 (OA) 进展而增加. 这一角度可以作为OA的新分级参数,类似于已建立的系统.
科学领域:
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 生物医学工程 生物医学工程
背景情况:
- 膝关节单部位性静脉性关节炎 (OA) 的特征是骨形变形和关节直线收角 (JLCA) 的增加.
- 关节内关节变形和侧面软组织松影响JLCA,使其成为膝关节关节不稳定的关键指标.
- 现有的OA分级系统,如Ahlbäck和Kellgren-Lawrence (KL),无法完全捕捉与软组织松相关的动态变化.
研究的目的:
- 调查关节直线收角 (JLCA) 与单个分隔体膝关节骨关节炎 (OA) 的进展之间的相关性.
- 评估JLCA的潜力,作为一种新的OA进展等级参数.
- 为了比较JLCA和其他对齐参数,高骨切除术 (HTO) 和单间膝关节关节整形术 (UKA) 组之间.
主要方法:
- 对501名接受高骨切除术 (HTO) 或单隔膝关节关节整形术 (UKA) 的患者进行了回顾性放射学分析.
- 使用阿尔贝克和凯尔格伦-劳伦斯 (KL) 尺度进行术前OA分级.
- 测量部-膝盖-脚角 (HKA),中侧近亲角 (MPTA),机械侧侧远侧角 (mLDFA) 和关节直线收角 (JLCA).
主要成果:
- 在Ahlbäck和KL分级系统中,在增加JLCA和OA进展之间发现了显著的关联 (p < 0.001).
- 与HTO组 (2.93° ± 1.82°) 相比,UKA组 (3.69° ± 2.1°) 的平均JLCA值更高.
- JLCA显示出较高OA等级的明显增加趋势,例如,Ahlbäck等级4的平均JLCA为7°±0.93°,KL等级4为4.89°±1.73°.
结论:
- 关节直线收角 (JLCA) 随着骨关节炎的严重程度逐渐增加.
- JLCA与已建立的OA分级系统 (Ahlbäck和KL) 有着显著的相关性.
- 膝关节骨关节炎 (JLCA) 具有作为膝关节骨关节炎进展的有价值,客观分级参数的潜力.

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Knee Joint
1.9K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Ankle Joint
1.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Articulations of the Vertebral Column
2.0K
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...

Structural Joints: Synovial Joints
3.6K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Joints

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable
