Patent number: 9393118Abstract: Provided are methods for processing a green body that includes compacted metal powder, comprising impacting the green body with a particulate material for a time and under conditions effective to displace a portion of the metal powder from the green body. The present methods can be used to prepare green bodies that have “roughened” surfaces and that can be used to make orthopedic implants displaying low movement relative to bone when installed in situ, which corresponds to higher stability upon implantation and decreases the time required for biological fixation of the implant. Also provided are implants comprising a metallic matrix, and methods comprising surgically installing an implant prepared from a “surface roughened” green body in accordance with the present invention.Type: GrantFiled: September 17, 2014Date of Patent: July 19, 2016Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Bryan J.
