<p>The present invention relates to a tapered implant for insertion into a bore hole arranged in bone tissue, said implant having a cancellous portion, and a cortical portion having an axial length such that, when installed in the bore hole, the engagement of said cortical portion with the bone tissue will generally be confined to the cortical bone tissue layer. Said cortical portion presents an outer surface which is threaded for accomplishing said engagement, and has an outer design such that, when being screwed into said bore hole under action of a screwing torque, said cortical portion acts so as to increase the compression of the cortical bone tissue.</p> |
