After bone fracture‚ many chemical and biological processes are triggered in the bone. After fracture‚ a cascade of signaling biomolecules and cellular changes induces bone healing simultaneously and sequentially. Generally‚ the bone healing process comprises four consecutive steps‚ that is‚ inflammation (reactive phase)‚ fibrocartilage callus formation (reparative phase)‚ bony callus formation (reparative phase)‚ and remodeling phase [31]. In the inflammatory phase‚ damage of vasculature results

Work Book Fractures When caring for a resident who has a cast‚ “elevate” the extremity that is in a cast to help stop swelling. Keep the cast “dry and clean” at all times. A bone must be “immobilized” to allow the fusion of fractured parts. Signs and symptoms of a fracture include “swelling.” Fractures are broken bones and may be caused by “osteoporosis.” You can place a wet cast on “Pillows” so that its shape is not altered as it dries. When can a resident insert something

A tibial plateau fracture is a break in the bone that forms the bottom of your knee joint (tibia or shinbone). The lower end of your thighbone (femur) forms the upper surface of your knee joint. The top of the tibia has a flat‚ smooth surface (tibial plateau). This part of your shinbone is made up of softer bone than the shaft of your shinbone. If a strong force drives your femur down into your tibial plateau‚ it can cause the tibial plateau to collapse or break away at the edges. A displaced tibial
