Abstract: 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.
Abstract translation: 提供了一种加工生坯体的方法，其包括压实的金属粉末，包括一段时间和在有效地将一部分金属粉末从生坯体移位的条件下，用生物体冲击生坯。 本发明的方法可用于制备具有“粗糙化”表面的生坯，并且可用于使矫形植入物在原位安装时显示相对于骨的低运动，这对应于植入时更高的稳定性并减少生物学所需的时间 固定植入物。 还提供了包括金属基质的植入物，以及包括手术安装由根据本发明的“表面粗糙化”生坯体制备的植入物的方法。
