概括
一个定制的杆肘部整形 (HEO) 并没有稳定侧侧侧带 (LCL) 缺陷的肘部. 这项研究建议在LCL损伤康复期间避免使用varus手臂位置,即使使用HEO.
科学领域:
- 骨科生物机械学 骨科生物机械学
- 肘部关节运动学 肘部关节运动学
- 关节损伤稳定 关节损伤稳定
背景情况:
- 商用肘部支架具有直立的链,忽视了肘部的自然承载角度.
- 侧侧侧带 (LCL) 损伤会损害肘部关节的稳定性.
研究的目的:
- 为了评估一个定制的链肘整形器 (HEO) 具有可调的角角的疗效.
- 为了评估HEO在稳定缺陷侧侧带 (LCL) 的有效性,肘部模型.
主要方法:
- 八个尸体的上肢受到了模拟的LCL损伤.
- 在各种模拟条件下,使用电磁跟踪系统分析了肘部运动.
- 测试了具有0°,10°和20°角角的定制HEO.
主要成果:
- 与完整状态相比,LCL损伤显著增加了肘部角的角和角.
- 定制的HEO,无论角,都没有显著改变伤害后的角-角角或角旋转.
- 在受损状态与没有HEO之间没有观察到稳定性的显著差异.
结论:
- 定制设计的杆肘部整形 (HEO) 无法为LCL缺陷的肘部提供额外的稳定性.
- 对于LCL受伤的肘部的康复方案应该避免臂位置,即使在使用HEO时也是如此.

Stability of structures
162
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Knee 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...
