概括
在"1.5阶段"间距协议中修复茎植入物减少了膝关节置换后周围假肢关节感染 (PJI) 的重新手术. 这种持久的间隔器方法对需要PJI治疗的精选患者显示出希望.
科学领域:
- 整形外科手术 整形外科手术
- 传染病管理 传染病管理
- 生物材料工程 生物材料工程
背景情况:
- 在全膝关节整形术 (TKA) 后,对周围假肢关节感染 (PJI) 的两阶段手术方案导致了显著的患者发病率.
- 持久的"1.5阶段"间隔器结构正在出现,作为减少患者负担的替代方案.
- 这项研究评估了一种新的"1.5阶段"间距器,使用了修复的茎植入物.
研究的目的:
- 评估用于管理膝关节PJI的新"1.5阶段"间距结构的结果.
- 为了比较"1.5阶段"膝关节PJI治疗中干部修改组件与手工制成组件的有效性.
- 评估与每个构造类型相关的短期生存率和重新运行率.
主要方法:
- 对接受"1.5阶段"膝盖PJI协议的患者进行了回顾性审查.
- 程序被分为手工构造或根基修订构造.
- 卡普兰-梅尔生存分析用于确定修订,间隔器松动和感染复发的2年结果.
主要成果:
- 与手工队列相比,干部修改队列显示出任何原因的重复手术率显着较低 (17.6%与50.0%,P=0.028) 和空间松动 (0.0%与25.0%,P=0.003) 的修订.
- 两组之间没有观察到感染复发率或修改时间的显著差异.
- 虽然从修改放松后的2年存活率在干队列 (100%) 与手工队列 (72.9%) 中较高,但这种差异在统计学上并不显著 (P=0.330).
结论:
- 一个"1.5阶段"间隔器构造,利用茎修订组件,证明了膝盖PJI的有希望的短期结果.
- 持久的间隔器结构,特别是那些带有茎修订组件的结构,可能为特定患者提供可行的治疗选择.

01:23Knee Joint
3.4K
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...

01:10Ankle Joint
3.4K
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...

01:07Development of the Limb Synovial Joints

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.
