概括
双流动性acetabular组件 (DMCs) 与单流动性 (SM) 组件相比,在高风险的关节整形术患者中显示出更低的脱位风险. 这项研究没有发现DMCs的并发症或修订风险增加.
科学领域:
- 整形外科手术 整形外科手术
- 生物材料工程 生物材料工程
背景情况:
- 在初级全关节置换术 (THAs) 中,双流动性关节元件 (DMCs) 的疗效仍在争论中.
- 单一移动性 (SM) 组件是标准的,但DMC被认为是高风险患者.
研究的目的:
- 为了比较DMCs和SM组件之间的脱位和并发症率在初级选修THAs.
- 为了评估两种类型的骨组成部分的修订率和生存结果.
主要方法:
- 追溯分析了1,940个 (2010-2019年) 的初级THA,使用无DMC或SM组件.
- 对于70岁以上或高脱位风险的患者,DMCs是适用的;对于其他人,SM组件.
- 收集和分析了有关并发症,修订和生存的数据.
主要成果:
- 在DMC组 (0.17%) 与SM组 (1%) (p=0.019) 相比,发生的脱位较少.
- 整体并发症率相似 (5.1%的DMC与6.7%的MS相比;p=0.214),没有DMC特定的问题.
- 修订率 (1.6%的DMC与1.9%的SM;p=0.709) 和5年无无菌修订生存率 (98%的DMC与97.3%的SM;p=0.780) 是相似的.
结论:
- 在中期随访时,单块DMC在高风险THA患者中的脱位风险降低,而在低风险患者中的SM组件降低.
- 在这个庞大的队列中,没有观察到DMCs对成分特定并发症或修订的显著增加.

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.

01:23Knee Joint
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 group...

01:10Ankle Joint
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...
