Patent ID: 11382678

Abstract:
A percutaneous method for removing an outer portion of the proximal end of a lag screw protruding from a fractured femur when embedded in the femur to stabilize an intramedullary nail implanted in the intramedullary canal using a multi-part cannulated driver wherein the lag screw comprises a distal section, an intermediate section including a channel formed in the proximal portion thereof with a driver recess formed at the distal end thereof, and a proximal section having a notch, groove or score mark formed on the exterior surface of the lag screw separating or between the intermediate section and the proximal section and the multi-part cannulated driver comprises a cannulated shaft including a first driver member formed thereon configured to engage the driver recess to prevent the distal section and intermediate section of the lag screw from rotating in the femoral head when torque is applied to the proximal section by a second driver member engaging the proximal section of the lag screw to separate the proximal section from the section and the intermediate section along the notch, groove or score mark.
