Muscles are attached to two or more bones at both ends, and when the muscles contract, the joint carries the bones to carry out activities. The movement of the human body can be roughly divided into extension, abduction and rotation movements, therefore, a large number of muscles are attached to each bone in order to meet the needs of the above activities. At the same time, in order to make the joint movement stable, there are usually certain ligaments connecting the two bones to ensure stability. The nerves mainly transmit to the body’s motor and sensory instructions, and the blood vessels are responsible for supplying oxygen and energy to the muscles and bones, so the body’s nerves and blood vessels are generally protected between the muscles, but of course there are some superficial blood vessels and nerves, which are vulnerable to injury. Bones, muscles, ligaments, nerves, and blood vessels always accompany each other, and because muscles, ligaments, nerves, and blood vessels have different hardness compared to bones, they are also called soft tissues. When a fracture occurs, there must be soft tissue damage around the fracture, and depending on the location of the fracture, different types of soft tissues may be damaged.
