The operation of most skeletal muscles involves leverage – using a lever to move an object. A lever is a rigid bar that moves on a fixed point called the fulcrum, when a force is applied to it. The applied force, or effort, is used to move a resistance, or load. In the human body, the joints are fulcrums, and the bones act as levers.

The bone levers are used in the trauma or prosthesis replace surgeries.
