BODY FOR PROVIDING INGROWTH AND GROWTH OF BONE TISSUE AND/OR CONNECTIVE TISSUE AND METHOD OF MAKING SUCH A BODY

摘要

A body, such as a grain, for providing ingrowth and growth of bone tissueand/or connective tissue. The body consistsof a plastic or non-essentially elastic biocompatible material, preferablymetal or metal alloy. It is also porous, having the followingporosity characteristics: (a) the porosity is continuous and (b) the openingof cavities/indentations/pockets and the ducts connectingthem has the width of about 50 µm for bone tissue and about 10 µmfor connective tissue. In a method of making such a body, thebody has been produced by blowing gas into a melt of metal. An advantageoususe of bodies according to the invention is enclosingthereof in a casing, formed with openings, for making an implant, such as aspinal implant.
