Abstract
The medullary canal plug is formed by a deformable and expandable outer body having a jacket formed of a number of segments and a conical expansion body which is pulled into the outer body in order to expand the outer body. Spreading of the outer body causes barb-like anchoring elements to hook into the inner wall of a bone. The two bodies are permanently secured together via serrations on the inside of the outer body and the outside of the expansion body.
