主权项

1. A tibial prosthetic component comprising:
a plurality of modular tibial stem component pieces configured to detachably couple together to form a modular tibial prosthetic stem component having a longitudinal axis; an interior circumscribing surface centrally disposed and axially extending through said modular tibial prosthetic stem component, said interior circumscribing surface defining a central longitudinal open ended bore extending along said longitudinal axis of said modular tibial prosthetic stem component for defining a cannulated modular tibial prosthetic stem component; and wherein each of said plurality of modular tibial stem component pieces comprises a centrally disposed and axially extending interior circumscribing component piece surface forming a distinct portion of said interior circumscribing surface of said cannulated modular tibial prosthetic stem component.
