概括
对骨高度的平原-骨角 (PPA) 评估可能因种族而异. 16°-24°的PPA范围似乎更适合台湾骨关节炎患者,而不是西方标准.
科学领域:
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 生物医学工程 生物医学工程
背景情况:
- 平原 - 骨角 (PPA) 是评估骨高度的一种新度量.
- 已确定的正常PPA范围 (21°-29°) 基于西方人口.
- 膝盖形态的种族差异可能会影响PPA,需要特定人口的数据.
研究的目的:
- 在台湾患有骨关节炎的患者中,确定平原 - 骨角 (PPA) 的参考范围.
- 调查在台湾队列中建立的西方PPA范围的适用性.
- 为了比较PPA与传统的骨高度指数.
主要方法:
- 在台湾接受全膝关节整形手术的患者中,从196个膝盖进行了手术前侧面放射图的分析.
- 使用平原 - 皮带角 (PPA),Insall-Salvati指数 (ISI),Caton-Deschamps指数 (CDI) 和Blackburne-Peel指数 (BPI) 评估皮带高度.
- 计算测量方法与PPA可靠性评估之间的相关性;将PPA范围 (21°-29°和16°-24°) 与传统指数进行比较.
主要成果:
- 平原-皮带角 (PPA) 与ISI有中度的相关性,与CDI和BPI有很高的相关性.

Angle of Twist - Elastic Range
844
Consider a cylindrical shaft with a length denoted by L and a consistent cross-sectional radius referred to as r. This shaft undergoes a torque at the free end. The highest shearing strain within the shaft is directly proportional to the twist angle and the radial distance from the shaft axis. When the shaft behaves elastically, this shearing strain can be articulated using variables such as the applied torque, radial distance, the polar moment of inertia, and the modulus of rigidity. By...

Bones of the Lower Limb: Femur and Patella
5.4K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Range
14.5K
The range is one of the measures of variation. It can be defined as the difference between a dataset's highest and lowest values. For example, in the study of seven 16-ounce soda cans, the filled volume of soda was measured, thus producing the following amount (in ounces) of soda:
15.9; 16.1; 15.2; 14.8; 15.8; 15.9; 16.0; 15.5
Measurements of the amount of soda in a 16-ounce can vary since different subjects record these measurements or since the exact amount - 16 ounces of liquid, was not...

Variation: Normal Distribution, Range, and Standard Deviation
28.8K
In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Contact Angle
26.6K
When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

Inertial Frames of Reference
9.0K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...
