Abstract
An orthopaedic prosthetic component comprises a fixation peg including a porous three-dimensional structure configured to permit bone in-growth. The porous three-dimensional structure has an outer surface boundary. The fixation peg includes a plate attached to the porous three-dimensional structure at the outer surface boundary. The plate includes a tapered body having an outer wall that faces away from the porous three-dimensional structure and is devoid of any openings.
Claims17
A method for implanting an orthopaedic prosthetic component, the method comprising the steps of:
- inserting a fixation peg into a bone of a human body to facilitate bone ingrowth into a porous three-dimensional structure of the fixation peg, wherein the porous three-dimensional structure has an outer surface boundary,
- wherein the fixation peg includes a plurality of plates attached to the porous three-dimensional structure at the outer surface boundary, each plate including a body having an outer wall that faces away from the porous three-dimensional structure, the outer wall defining a channel that has an open distal end to facilitate insertion of the fixation peg into the bone during the implanting step.
