The present invention provides for a variety of fracture fixation options should a fracture occur after total hip arthroplasty or total knee arthroplasty, and provides associated methods and apparatus for application of provided fixation. The ability to pre-engineer fracture fixation contingent solutions into femoral or tibial components provides for a distinct clinical advantage in the planning and execution for periprosthetic fracture fixation. Said methods and apparatus include targeting devices which allow for intimate association of fixed angle locking screws in pre-drilled holes in an existing prosthetic, femoral nail, or other components including additional fixation components. Use of pre-engineered fracture fixation contingent solutions into femoral or tibial components provides for a distinct clinical advantage in the planning and execution for periprosthetic fracture fixation. Such apparatus and methods further include the use of alignment devices and other components to allow for ease of repair of periprosthetic fractures utilizing the pre-engineered solutions. Such targeting devices are required in specific circumstances as the prosthetics may prevent x-ray imaging and consequently free hand alignment. |
