まとめ
膝蓋骨の高さに対するプレート・パテラ・アングル (PPA) 評価は,民族によって異なる場合があります. 16°~24°のPPAの範囲は,欧米の標準よりも台湾の骨関節炎患者に適しているようです.
科学分野:
- 整形外科 整形外科 整形外科
- 放射線学 放射線学
- バイオメディカルエンジニアリング
背景:
- プレート・パテラ・アングル (PPA) は,パテラの高さを評価するための新しいメトリックです.
- 確立された正常PPA範囲 (21°-29°) は,西欧の集団に基づいています.
- 膝の形状の民族的変異はPPAに影響し,人口特有のデータが必要になります.
研究 の 目的:
- 台湾の骨格関節炎患者におけるプラトー・パテラ角 (PPA) の基準範囲を確立する.
- 台湾のコホートにおける確立された西部のPPA範囲の適性を調査する.
- PPAを従来のパテラの高さ指数と比較するために.
主な方法:
- 全膝関節整形手術を受けた台湾の患者の196本の膝の手術前側線写真の分析.
- プレート・パテラ・アングル (PPA),インサール・サルヴァティ・インデックス (ISI),カトン・デシャンプス・インデックス (CDI),ブラックバーン・ピール・インデックス (BPI) を用いたパテラの高さの評価.
- 測定方法とPPAの信頼性の評価の相関の計算;PPAの範囲 (21°-29°および16°-24°) を従来の指標と比較.
主要な成果:
- プレート・パテラ・アングル (PPA) は,ISIと中程度の相関関係,CDIとBPIと高い相関関係を示した.
- 従来のPPA範囲 (21°-29°) は,他の指標と比較して,異常なパテラ位置 (64%) の割合が高かった.
- 16°~24°のPPAの範囲は,既定のインデックスに匹敵する結果をもたらし,このコホートにおけるよりよい適用性を示唆しています.
結論:
- プレート・パテラ・アングル (PPA) は,異なる民族の間で慎重に解釈する必要があります.
- 16°-24°のPPA基準範囲は,台湾の骨関節炎患者にとってより適切であると示唆されています.
- この発見は,放射線測定を適用する際の民族的考慮の重要性を強調しています.

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...
