概括
青少年的外向骨扭转 (TT) 或大腿前转 (FA) 呈现改变膝盖机械在跳跃下降. 整形手术使这些运动正常化,并改善了患者的治疗结果.
科学领域:
- 整形外科 整形外科 整形外科
- 生物力学 生物力学
- 儿科外科手术 儿科外科手术
背景情况:
- 长骨的旋转变形,如过度向外的小腿骨扭转 (TT) 和大腿骨前转 (FA),在异态患者群体中并未得到充分理解,特别是在动态活动期间.
- 以前的研究主要集中在平坦的地面上行走,限制了对跳跃等复杂运动的洞察力.
研究的目的:
- 为了研究患有特异性旋转形 (TT,FA或两者) 的青少年跳跃的病理机制.
- 评估正手术在正常化动力学,动力学和改善患者报告结果方面的有效性.
主要方法:
- 跳跃的计算运动分析在35名青少年身上进行,这些青少年在正手术前后患有旋转形.
- 用儿科结果数据收集仪器 (PODCI) 和目标实现得分来评估患者报告的结果.
- 结果与25名典型发育的青少年组成的对照组进行了比较.
主要成果:
- 患有FA的青少年在部得到补偿,而TT的青少年没有,导致膝盖和脚的进展角度发生变化.
- 与对照组相比,观察到额面平面膝盖时刻 (FA) 和侧面膝盖力 (所有组,在TT中显著) 的升高.
- 旋转骨切除术使动力学和动力学正常化,减少疼痛和改善功能能力,FA组的改善更大.
结论:
- 患有旋转形的青少年在跳跃时采用补偿策略,这些策略不能完全减轻膝盖力量的增加.
- 手术纠正有效地使生物力学正常化,减少疼痛,增强功能感知.
- 跳下跳下分析为这些变形的病理机制和手术干预的有效性提供了宝贵的见解.

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...

Consider a crane whose telescopic boom rotates with an angular velocity of 0.04 rad/s and angular acceleration of 0.02 rad/s2. Along with the rotation, the boom also extends linearly with a uniform speed of 5 m/s. The extension of the boom is measured at point D, which is measured with respect to the fixed point C on the other end of the boom. For the given instant, the distance between points C and D is 60 meters.
Here, in order to determine the magnitude of velocity and acceleration for point...
