概括
这项研究引入了足高度乘数,用于预测四肢长度差异. 虽然脚高度的增长与下肢的其他组成部分不同,但对差异计算的影响很小,特别是在年长的儿童中.
科学领域:
- 整形外科 整形外科 整形外科
- 儿科整形外科 儿科整形外科
- 放射学 放射学是一门学科.
背景情况:
- 乘法估计残余的成长到骨成熟度为四肢长度差异预测.
- 对于下肢的现有乘数不考虑脚高度,需要对其生长轨迹进行调查.
- 足高乘数的X光学数据缺乏,对其相对于大腿骨和骨的发育速度产生不确定性.
研究的目的:
- 使用连续射线图像计算脚高度乘数.
- 为了比较衍生的脚高度乘数与现有的下肢和脚长度乘数.
- 评估在四肢长度差异计算中使用单独的脚高度乘数的临床意义.
主要方法:
- 利用Bolton Brush的射线图集进行横向足部视图测量.
- 针对年龄的计算乘数,至少有10次连续研究访问.
- 包括212名患者 (2195张X射线图),并确定了0-17岁 (女性) 和0-18岁 (男性) 的倍数.
- 被归类为第三级回顾性比较研究.
主要成果:
- 脚高度乘数随着年龄的增长而下降,在女性13岁左右和男性15岁左右停滞不前.
- 与脚高度相比,下肢倍数表现出更明显的生长曲线.
- 使用脚高度乘数与下肢乘数计算的四肢长度差异计算的差异可以忽略不计.
结论:
- 建立了脚高度乘数的数据库,表明与其他下肢组件不同的生长轨迹.

01:11Pulse Assessment Sites
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
01:12Differential Leveling
Differential leveling is a precise method in surveying used to determine the elevation difference between two points. Its primary goal is to establish accurate vertical measurements to create level surfaces or grade lines critical for designing and constructing infrastructures such as roads, bridges, and buildings.The procedure for differential leveling begins with setting up and leveling the instrument at a point where the benchmark can be seen. The level rod is held on the benchmark (BM), and...
01:26Profile Leveling and Cross Sections
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes. Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the instrument's...
