Abstract: Various different porous screws and pegs are disclosed herein, as are methods of manufacturing such porous pegs or screws. The porous screws and pegs, in certain examples, are formed through additive manufacturing and have improved porosity for bone ingrowth. In certain cases, additive manufacturing or another manufacturing technique can be used to cover only part or all of the threads of the screws or pegs disclosed herein with a porous material. Such screws or pegs can have porosity but also threads that are capable of effectively digging into bone.

Abstract: An acetabular cup assembly includes a shell and a liner. The shell has an inner surface, an outer surface, a face positioned at an upper end of the shell, and an apex positioned at a lower end of the inner surface. The inner surface includes a tapered inner wall and a plurality of inwardly-facing recesses provided along the inner surface adjacent the face. The plurality of inwardly-facing recesses include a main portion and an asymmetrically-extending portion. Each of the asymmetrically-extending portions extend circumferentially in one direction resulting in the recesses having an asymmetric shape. The segmented portion of the tapered inner wall has a wide portion between the asymmetrically-extending portion and the face and a narrower portion between the asymmetrically-extending portion and the adjacent inwardly-facing recess. The liner is adapted to fit within the shell and engage the inner surface of the shell establishing an interference fit.

Abstract: Method and apparatus for preparing a seating surface of prescribed depth, contour configuration and area delineated by a prescribed peripheral boundary extending along the bone of a natural joint at which a prosthetic device is to be implanted includes positioning a guide on the bone, the guide having a guide slot following a path geometrically similar to the peripheral boundary of the seating surface, inserting a cutting device altitudinally through the guide slot at any selected location along the path of the guide slot, and translating the cutting device along the guide slot to cut an outline groove in the bone coincident with the peripheral boundary of the seating surface. The guide then is removed from the bone, and portions of the bone lying within the area delineated by the outline groove are removed to establish the seating surface.
