Abstract
An orthopaedic surgical instrument for use in disassembling an orthopaedic prosthesis includes a main component, a rod, and a spindle. The main component has a housing and an elongated body extending from the housing with a passageway is defined in the elongated body. The rod has an elongated shaft, with a greater length than the elongated body, extending from the head of the rod and configured to pass through the main component. The spindle threads into the housing to move the rod along a longitudinal axis.

10. A method for disassembling a femoral component assembly, the method comprising:
-
securing an end of a main component to a femoral component, advancing a rod in a first direction through the main component and into contact with a stem component secured to the femoral component and positioned in a bone of a patient, threading a spindle component into the main component to apply a force in the first direction to the rod, continuing to thread the spindle component into the main component to increase the force applied in the first direction to disengage the femoral component from the stem component. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method for disassembling an orthopaedic prosthesis assembly, the method comprising:
-
securing an end of a first surgical instrument to a first prosthetic component, advancing a rod in a first direction through the first prosthetic component and into contact with a second prosthetic component secured to the first prosthetic component, threading a second surgical instrument into the first surgical instrument to apply a force in the first direction to the rod, and continuing to thread the second surgical instrument into the first surgical instrument to increase the force applied in the first direction to the rod to disengage the first prosthetic component from the second prosthetic component. - View Dependent Claims (18, 19, 20)
