âSherpa lining,â in the garment industry, refers to a polyester lining with a deep pile and large, fuzzy ânapsâ that give it a bumpy texture. The overall effect is similar to real sheepâs wool, but sherpa lining is lighter weight, much less bulky, and faster-drying. Itâs also considerably cheaper, and avoids any ethical concerns about animal products.
A broken bone, or fracture, happens when excessive force applied to your bone causes it to break or shatter. Some fractures break the bone completely, while others just cause a crack in the bone. Fracture types vary depending on the circumstances of your injury and the amount of force applied to the bone. A simple fracture happens when the bone is broken into two pieces. 2  An open or compound fracture happens when a piece of bone protrudes through your skin or if the force of the injury breaks the skin. 3  A closed fracture happens when the bone is broken, but the skin is intact.
Open fracture. If a bone breaks in such a way that bone fragments stick out through the skin or a wound penetrates down to the broken bone, the fracture is called an open or compound fracture. Open fractures often involve much more damage to the surrounding muscles, tendons, and ligaments.
