概括
手部骨关节炎患者在未受影响的手指关节中表现出更窄的关节空间,这表明系统性倾向于软骨损伤. 这表明手骨关节炎可能是一种影响整体关节健康的全身性疾病.
科学领域:
- 类风湿病学 类风湿病学
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
背景情况:
- 手部骨关节炎 (OA) 是一种影响关节健康的常见疾病.
- 手部OA的系统性质,特别是际OA (IPOA),仍在调查中.
- 以前的研究表明,潜在的系统因素会影响OA的发展.
研究的目的:
- 为了研究手部OA的系统性特征.
- 测试手部骨质炎患者在受影响和未受影响的关节中表现出更窄的关节空间的假设.
- 探索IPOA是否与普遍的关节空间缩小有关.
主要方法:
- 对3394名参与骨关节炎倡议的参与者的主导手部X射线图进行分析.
- 将病例定义为具有IPOA的个体 (Kellgren和Lawrence得分≥2) 和没有IPOA的对照.
- 使用定制软件测量元手腕关节,近端关节和远端关节的关节空间宽度 (JSW).
- 使用概括估计方程模型,在IPOA病例和对照组之间,在没有放射性OA的关节中比较JSW.
主要成果:
- 与对照组相比,没有放射性OA的手指关节在IPOA组中表现出明显更窄的JSW (p < 0.001).
- 这种差异在所有关节类型中都是一致的 (元手腕关节,近端关节,远端关节).
- 在总联合测量和特定子区域 (中心和侧面) 观察到更窄的JSW.
结论:
- 与健康对照组相比,患有IPOA的人在未受影响的手指关节中表现出更窄的关节空间.
- 这些发现支持了手部OA的系统性质的假设.
- 结果表明,在手手OA患者中,可能存在对一般性软骨恶化的倾向.

Bones of the Upper Limb: Radius
2.2K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

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...

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...

Development of the Limb Synovial Joints
1.4K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Bones of the Upper Limb: Humerus
3.3K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
