Ankle Joint01:10

Ankle Joint

1.7K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Normal Stress01:19

Normal Stress

627
Normal stress is a type of stress that occurs when forces act perpendicular, or normal, to a material's cross-sectional area. This stress often arises in structures when subjected to axial loading, which is the application of force along the axis of an object. A practical example of this can be found in bridge truss members.
When a rod is under axial loading, the internal forces and corresponding stress are normal to the plane of the section, so it is termed normal stress. It's...

Unsymmetric Bending - Angle of Neutral Axis01:15

Unsymmetric Bending - Angle of Neutral Axis

363
Unsymmetrical bending occurs when a structural member is subjected to bending moments in a plane that does not align with the member's principal axes. This scenario typically arises in beams and other structural components when loads are applied at non-ideal angles, introducing complexities in stress analysis.
When a bending moment is applied at an angle θ concerning the vertical axis of a symmetrical member, it can be resolved into components along the member's principal...

Beams with Unsymmetric Loadings01:17

Beams with Unsymmetric Loadings

149
Analyzing a supported beam under unsymmetrical loadings is essential in structural engineering to understand how beams respond to varied force distributions. This analysis involves calculating the deflection and identifying points where the slope of the beam is zero, which are crucial for ensuring structural stability and functionality.
The first moment-area theorem determines the slope at any point on the beam. This theorem indicates that the change in slope between two points on a beam...

Unsymmetric Bending01:18

Unsymmetric Bending

376
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from those in symmetrical bending, and are essential for designing structures to withstand different loading conditions. In unsymmetrical bending, the neutral axis—where stress is zero—does not necessarily align with the geometric axes of the cross-section. The...

Regression Toward the Mean01:52

Regression Toward the Mean

6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

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.
  • 足部医学是一门专业.

背景情况:

  • 在前足手术中,手术规划和结果评估通常依赖于对"正常"和"异常"的主观定义.
  • 缺乏客观的标准,以评估小脚对齐使用metatarsophalangeal角度 (MTPAs) 在dorsoplantar (DP) 视图.

研究的目的:

  • 确定骨科外科医生和放射科医生认为"正常"的2-5元角角 (MTPAs) 的范围.
  • 评估对较小脚对齐的主观解释的可靠性.

  • 30张匿名脚部X射线图由骨科外科医生和放射科医生进行了两次审查.
  • 观察员将"正常"",边界正常"和"异常"等术语分配给特定的MTPA (2-5).
  • 分析了观察者内部和观察者间的可靠性.

主要成果:

  • "正常"MTPA的确定的主观范围是:MTP-2 (0°至 -20°),MTP-3 (0°至 -15°),MTP-4 (0°至 -10°) 和MTP-5 (5°valgus至15°varus).
