Abstract
A torque-limiting fastener driver for driving a bone fastener into bone includes a handle supporting a driver shaft. The driver shaft includes limited components which are designed to provide feedback to a user regarding the applied torsional force. In addition, the driver shaft is designed to controllably fail before any potential uncontrolled failure of the distal driving tip. This prevents application of too much torque and controlled design of the shape and size of the failed components.
