Implantable article with ablated surface

摘要

An implantable article includes a textured bone engaging surface having a surface texture pattern formed by a plurality of furrows separated by ridges that are integral with the base material from which the article is formed. The furrows are formed by ablating in the surface a series of intersecting holes. The side walls of the furrows have scalloped edges. The ablating energy can be applied by techniques such as laser ablation and hydrojet ablation.
