Bone void filler and method of manufacture |
摘要 |
Bone void filler pieces that are conducive to packing or nesting when a plurality of pieces are located in a cavity in random orientation. The bone void filler of the present invention includes a higher bulk packing density and a porosity of less than 80% to provide a better match native bone ingrowth rate. Further, the bone void filler includes a bi-modal pore distribution with a high frequency of smaller pores to enhance the density characteristic of the bone void filler pieces. A method of manufacturing the bone void filler pieces includes a precursor powder composition suitable to form a ceramic matrix; the preform is converted by chemical reaction to a final composition. The preform further includes the use of a porogen that decomposes to gaseous decomposition products upon heating.
