Abstract
A bone screw is provided with a resilient component that enables a surgeon to measure the amount of compression effected by the bone screw during installation and dynamically maintain that compression across the provided bone screw during fracture healing. The provided bone screw includes a leading component, a trailing component, and a resilient component that may be compressed between the leading and trailing components and which is arranged such that the bone screw's axial rigidity is maintained. The leading and trailing components may be engaged together or independently by a driving instrument. Advancing or receding only the leading component or only the trailing component alters a compression force effected by the bone screw between two bone fragments, enabling a surgeon to set a desired compression force. A measurement tool is also provided that may be used to measure an amount of compression force effected by an installed bone screw.
