Plug-like anchoring for the cement-free fixation of bone implants

Abstract

Abstract 1. A plug-like anchorage for the cement-free fixing of bone implants, more particularly of femur and/or tibia parts of artificial knee joints, comprising a hollow member (6), open at one end and expandable by means of longitudinal slots (8), and an expansion member (1) which can be driven into the hollow member, at least the hollow member bearing barb-like toothing on its outer generated surface, characterised in that the expansion member (1) has longitudinal recesses (3) which are adapted in shape, dimensions and position to the generated webs (7) remaining on the hollow member (6) between the longitudinal slots (8), and between which there protrude projections (4) also provided with barb-like toothing and adapted in external diameter to the external diameter of the hollow member (6).
