A tool and a method are provided for driving a bone pin into a fractured bone to stabilize the fractured bone by maintaining the fractured bone in a reduced state. The tool may be a handheld device including a cartridge having at least one passageway that receives the bone pin. The tool may also include a pneumatically-powered piston having a needle that is sized for receipt within the passageway of the cartridge, the needle applying sufficient force to the bone pin to drive the bone pin out of the cartridge and into the fractured bone.
