Fractures of the coronoid rarely occur in isolation. They usually occur in combination with a radial head fracture, a dislocation of the elbow, or both (terrible triad of the elbow).Large coronoid fractures often are associated with persistent elbow instability even after reduction of the dislocation.
Hydrothermal Vents. Measurement of tectonic plate movements. The amount of tectonic plate movement is measured using Global Positioning System (GPS) satellites and a network of GPS receivers. This technology allows scientists to measure plate movements as small as a few millimeters per year. click here to plot REAL-TIME data and visualize tectonic plate movement.
Inclinometers are used to monitor subsurface movements and deformations. Typical applications include: Detecting zones of movement and establish whether movement is constant, accelerating, or responding to remedial measures. Checking that deformations are within design limits, that struts and anchors are performing as expected, and that adjacent buildings are not affected by ground movements.
