<p>An endoprosthetic bone joint device is secured by filamentary elements driven therethrough into penetrating engagement with bone. These elements will normally exhibit transverse flexibility; they preferably have elastic modulus similar to bone; they can be roughened or barbed for added securement; they can carry material of negative electrochemical potential relative to other parts of the device to induce bone growth intimately therewith; and they can carry material otherwise beneficial to bone growth. The device preferably also has a radiating multi-directional flange formation to engage a corresponding formation cut in the bone.</p> |
