A scaphoid (carpal navicular) fracture is the displacement of one of the eight bones of the wrist joint. It is located between the radius bone of your forearm and the base of the thumb. You can identify it by holding your thumb in a "hitch-hiking" position. The primary cause of scaphoi...
X-ray:An X-ray will take pictures of your bones to see if you have an avulsion fracture. Stress X-ray: During astressX-ray, your doctor will apply tension to the injury to determine the joint's stability. However, stress X-rays are becoming less common because of the risk of displac...
We will go through the most important ones with you and describe how they can be recognized and evaluated on an MRI image. Cruciate ligaments We will now dive into the center of the knee joint to look at the cruciate ligaments. The anterior and posterior cruciate ligaments are very important...
Based on ROC analysis and Youden's J statistic, the optimal threshold for differentiating stable from an unstable Weber B fracture was 2.3 mm of displacement (AUC 0.81; sensitivity 77.8%; specificity 80%). The control group showed no difference in any of the measurements...
a change in the mode of bedding, volume, internal structure, or relative position of a body of rock under the action of deep-seated forcesthat give rise to conditions of unidirectional or multidirectional extension, compression, or displacement (see). ...
A tooth luxation isa dislodgment of the tooth from its normal position in the alveolus. Lateral luxation is defined as displacement of the tooth other than axially. Displacement is accompanied by contusion, comminution or fracture of the alveolar bone....
We describe the operative management of extended lateral column fractures according to the revised three-column classification approach in a step-by-step fashion. We show that direct reduction and stable fixation of extended lateral column tibial plateau fractures via a limited arthrotomy and tibia con...
Metatheoretical calculus is an umbrella term for a (semi)- formal system to describe, define, and constrain the process of adjudicating over theories in a given (sub)field. Metatheoret- ical calculi are for understanding and improving the process of science, for making transparent what ...
The term “material state” represents any solution-dependent internal variables that are required to describe the material. Examples of such variables are plastic strain tensor components, current yield stress, back stress tensor components, damage parameters, effective plastic strain, etc. The choice ...
You can measure the volume of a marble a couple of different ways. One is by direct measurement of the diameter. Another is by displacement when submerged in water. The latter may be more appropriate if you want to find the volume of a large number of ma
