Bone fracture refers to a medical condition where there is a break or crack in one or more bones in the body. This can occur due to various reasons such as falls, accidents, injuries, or even certain diseases that weaken the bones. When a bone fractures, it may cause pain, swelling and difficulty in movement. The severity of the injury depends on factors like the location of the break, whether it is a complete or incomplete fracture, and how well the bone heals after treatment. Treatment for bone fractures typically involves immobilization of the affected area using casts, splints or braces, followed by physical therapy to help regain strength and mobility in the injured limb.
