まとめ
膝関節置換手術後の不十分な骨折はまれですが,深刻です. ヴァルガス膝の整合は,骨の密度を下げ,手術中に骨折のリスクを増やす可能性があります. 注意深く切除する深さは鍵です.
科学分野:
- 整形外科 整形外科
- バイオメディカルエンジニアリング
- 放射線学 放射線学
背景:
- 膝関節整形手術 (TKA) の後の不十分性近義肢骨折は,まれながらも深刻な合併症である.
- TKAにおけるヴァルガス・アラインメントは,メディアル・フェムラル・コンディルの慢性的な解荷につながり,局所骨鉱質密度 (BMD) を低下させ,骨折のリスクを増やす可能性があります.
研究 の 目的:
- 骨のミネラル密度 (BMD) を比較するには,膝の全関節整形手術を受けた膝のヴァルガスとヴァルスの間の遠足骨の骨のミネラル密度 (BMD) を比較します.
- ヴァルガスの膝におけるローカル骨の質に対するディスタル股関節切除の深さの効果を調査する.
主な方法:
- 40のヴァルガス膝と40のプロペンシティスコアを元に戻した研究で,プライマリTKAを受けたバラス膝のスコアが一致しました.
- 定量コンピューティングトモグラフィー (QCT) を使用して,遠足の切除平面でのBMDを測定しました.
- 多様な深さ (のレベル,2mm深さ,4mm深さ) の遠側股関節切除のシミュレーションは,ヴァルガス膝で実施されました.
主要な成果:
- ヴァルガスの膝は,ヴァルガスの膝と比較して,特に中央側で,中央股関節のBMDが低く示されました.
- バルグスの大きな整列は,中央のBMDの減少と相関しています.
- ヴァルガス膝のより深いシミュレートレセクションレベルは,徐々に低いBMDをもたらしました.
- 中間切除の深さは,測定されたすべての領域で,より低いBMDと関連していました.
結論:
- ヴァルグスの膝のメディアル・ディスタル・フェムールは,比較的オステオペニックです.
- ヴァルガス膝のより深い遠隔股関節切除は,好ましくは低密度の骨を巻き込み,骨折のリスクを高めます.
- ヴァルガス矯正中にメディアル・ディスタル・フェモラル切除の深さを注意深くコントロールすることは,早期不十分な骨折のリスクを軽減するために不可欠です.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

3.3K
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...

01:20Elevation of Intermediate Points on Vertical Curves
308
Vertical curves are essential in roadway design because they provide smooth transitions between varying roadway grades. Designing vertical curves involves calculating intermediate elevations and identifying the curve's highest or lowest point, which is essential for optimal roadway performance.Intermediate elevations on a vertical curve are determined using the tangent offset method. This method considers the initial elevation at the start of the curve, the grades, and the curve's geometry. The...

01:18Reducing Line Loss
393
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

00:56Density
20.0K
Density is an important characteristic of substances, crucial in determining whether an object sinks or floats in a fluid. Its SI unit is kg/m3, and its cgs unit is g/cm3. The density of an object helps in identifying its composition, and also reveals information about the phase of the matter and its substructure. The densities of liquids and solids are roughly comparable, consistent with the fact that their atoms are in close contact. However, gases have much lower densities than liquids and...

01:21Current Density
5.2K
The total amount of current flowing through one unit value of a cross-sectional area is referred to as current density. If the current flow is uniform, the amount of current flowing through a conductor is the same at all points along the conductor, even if the conductor area varies. The current density consists of the local magnitude and direction of the charge flow, which varies from point to point. Current density is measured in amperes per meter square, and direction is defined as the net...
