Ankle Joint01:10

Ankle Joint

3.0K
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...

Exceptions to the Octet Rule

Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three categories:

Lewis Symbols and the Octet Rule

81.1K
Chemical bonds are complex interactions between two or more atoms or ions, which reduce the potential energy of the molecule. Gilbert N. Lewis developed a model called the Lewis model that simplified the depiction of chemical bond formation and provided straightforward explanations for the chemical bonds seen in most common compounds.

The Aufbau Principle and Hund's Rule03:02

The Aufbau Principle and Hund's Rule

73.0K
To determine the electron configuration for any particular atom, we can build the structures in the order of atomic numbers. Beginning with hydrogen, and continuing across the periods of the periodic table, we add one proton at a time to the nucleus and one electron to the proper subshell until we have described the electron configurations of all the elements. This procedure is called the aufbau principle, from the German word aufbau (“to build up”). Each added electron occupies the...

Decision Making01:20

Decision Making

991
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Calculating the Equilibrium Constant02:46

Calculating the Equilibrium Constant

38.1K
The equilibrium constant for a reaction is calculated from the equilibrium concentrations (or pressures) of its reactants and products. If these concentrations are known, the calculation simply involves their substitution into the Kc expression.
For example, gaseous nitrogen dioxide forms dinitrogen tetroxide according to this equation:

Summary
This summary is machine-generated.

The Ottawa Ankle Rule guides clinicians on assessing ankle trauma patients. It identifies key tenderness points to decide if imaging, like X-rays, is necessary, improving diagnostic efficiency.

Area of Science:

  • Orthopedic diagnostics
  • Trauma assessment
  • Radiographic decision-making

Background:

  • Ankle injuries are common, often requiring imaging to rule out fractures.
  • Clinical decision rules can optimize the use of diagnostic imaging.
  • The Ottawa Ankle Rule is a widely used tool in emergency settings.

Purpose of the Study:

  • To evaluate the effectiveness of the Ottawa Ankle Rule in guiding imaging decisions for ankle trauma.
  • To determine the specific areas of tenderness assessed by the rule.
  • To assess the rule's utility in identifying patients needing radiographic examination.

Main Methods:

  • The Ottawa Ankle Rule involves palpating specific bony landmarks and soft tissues around the ankle and foot.
  • Tenderness in the posterior malleolus, lateral malleolus, navicular bone, or fifth metatarsal base indicates potential fracture.
  • The rule aims to identify patients with ankle injuries who do not require X-rays.

Main Results:

  • The Ottawa Ankle Rule demonstrates high sensitivity in detecting ankle fractures.
  • It effectively reduces unnecessary radiography in patients with ankle trauma.
  • Specific areas of tenderness are clearly defined for clinical assessment.

Conclusions:

  • The Ottawa Ankle Rule is a valuable tool for clinicians managing ankle trauma.
  • Its application can lead to more judicious use of diagnostic imaging.
  • Accurate assessment of tenderness points is crucial for rule efficacy.
