摘要: A method of manufacturing an osteoinductive osteoimplant is provided which comprises the steps of: demineralizing part or all of at least one surface of a monolithic section of cortical bone to a depth of at least about 100 microns; and, configuring the monolithic section of cortical bone to provide an osteoimplant possessing an outer surface possessing at least one demineralized zone and a non-demineralized zone. An implant produced according to the above method demonstrates improved osteoinduction without producing any clinically significant reduction of strength in critical regions of the osteoimplant.

摘要: An osteoimplant is provided which comprises a coherent aggregate of elongate bone particles, the osteoimplant possessing predetermined dimensions and shape. The osteoimplant is highly absorbent and sponge-like in nature. Also provided herein are a method of fabricating the osteoimplant and a method of repairing and/or treating bone defects utilizing the osteoimplant.
