Systems and methods for mechanical bone growth to aid in promoting and accelerating bone growth are disclosed. In one implementation, a system may include a control unit, a mechanical bone growth stimulator with one or more stimulating mechanical discs configured to convert electrical energy into mechanical energy, and an electrical wire to electrically couple the control unit with one or more mechanical bone growth stimulators. The mechanical bone growth stimulator may provide various mechanical stimulations to a fractured or injured bone to decrease the time needed to heal or fuse the bone together.
