Attachment means for attaching an implant to bone tissue

摘要

The attachment means have a shank 3 which is made from resorbable material which expands after it has been implanted. The outer circumference of the shank 3 is formed in such a manner that it can be placed in a hole 6 in the bone tissue by exerting a force only in the longitudinal direction. As a result of expansion, the shank becomes fixed in the hole 6 and may be of relatively small diameter, with the result that when the material breaks off a limited concentrated amount of material is released into the body. <IMAGE>
