Bone, Muscle, & Joint Injuries
The musculoskeletal system is made of bones that form the skeleton along with muscles, tendons, ligaments, and joints. These things give the body shape, form, and stability. The bones and muscles work together to make body parts move.
A fracture is a break, chip, or crack in a bone. Fractures are usually caused by direct or indirect forces. Strong twisting forces and muscle contractions can also cause a fracture.
A dislocation is a separation of a bone from its normal position at a joint. Dislocations are usually caused by strong forces. Some joints, such as the shoulder or fingers, dislocate relatively easily because their bones and ligaments provide less protection.
A sprain is a tearing of ligaments at a joint when the bones are forced beyond their normal range of motion. The sudden forcing of a joint can completely rupture ligaments and dislocate bones. The bones may also fracture.
A strain is a stretching and tearing of a muscle or tendon. It is sometimes called a muscle pull or tear. Strains often result from lifting something too heavy, working a muscle too hard, or moving suddenly. Strains are common in the neck or back, the front or back of the thigh, or the back of the lower leg.
Although not an injury, muscle cramps are a type of pain that occurs after heavy exercise or if the arm or lef is in the same position for a long time.
