A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. [1] Symptoms include pain, bruising, and rapid-onset swelling. [1] The ulna bone may also be broken. [1] In younger people, these fractures typically occur during sports or a motor vehicle collision. [2]
The spinning drop method is convenient compared to other widely used methods for obtaining interfacial tension, because contact angle measurement is not required. Another advantage of the spinning drop method is that it is not necessary to estimate the curvature at the interface, which entails complexities associated with shape of the fluid drop.
The radial inclination of a distal radius fracture is shown in red in image at right. The angle is measured between: [4] [5] A line drawn between the distal ends of the articular surface of the radius on an AP view of the wrist. A line that is perpendicular to the diaphysis of the radius. Radial inclination is normally 21-25°. [6]
Plate pinches Place the weight plate on the ground standing upright on its side. Bend down and hold the plate using a pinch grip between your fingers and thumbs only. The plate shouldn't touch the palm of your hand. Straighten up and lift the plate using the pinch grip, up to your chest, and then slowly place it back on the ground.
However, the term now tends to be used loosely to describe any fracture of the distal radius, with or without involvement of the ulna, that has dorsal displacement of the fracture fragments. Colles himself described it as a fracture that “takes place at about an inch and a half (38mm) above the carpal extremity of the radius” and “the ...
Torsion of a square section bar Example of torsion mechanics. In the field of solid mechanics, torsion is the twisting of an object due to an applied torque [1] [2].Torsion could be defined as strain [3] [4] or angular deformation [5], and is measured by the angle a chosen section is rotated from its equilibrium position [6].
The hand now has a deformed appearance. The only procedure that can be done is the total wrist fusion, where a plate is inserted on the top of the wrist from the radius to the carpals, effectively freezing all flexion and movement in the wrist. Rotation is still possible as it is controlled by the radius and ulna.
Percutaneous pinning is considered to be less invasive, faster, and requires less skill compared to open surgery (plate fixation). [ 1 ] Disadvantages of this technique include that the stabilized fracture is less stable compared to a surgical plate, the person may require extensive limits to their motion at the early stages, and there is a ...
