Claim 0:
1. A compound medical implant for fixation and integration with hard bone tissues, the compound medical implant comprising:
a base member including a solid annular body and a void space, defined by opposed superior and inferior surfaces, configured to contact first and second hard bone tissues of a patient;
one or more rotational mechanisms centered on an axis;
one or more biocompatible rods that are permanently attached to the base member wherein:
the biocompatible rods are approximately parallel to the opposed superior and inferior surfaces and traverse through the solid annular ring body and the void space,
the biocompatible rods are rotatable, and
the one or more rotational mechanisms rotate around the biocompatible rods using the biocompatible rod;

one or more screws pushing the one or more rotational mechanisms such that the one or more rotational mechanisms rotate about the axis, wherein rotation of the one or more rotational mechanisms is less than rotation of the one or more screws, and
one or more protrusions attached to each of the one or more rotational mechanisms, the one or more protrusions urged into the hard bone tissue by the one or more rotational mechanisms, each protrusion having a proximal end attached to the one or more rotational mechanisms and a distal end configured to penetrate and become lodged into the hard bone tissue at an integration site, wherein:
at least a distal end of a first protrusion is configured to penetrate and become lodged into the hard tissue at a first integration site of the first hard bone tissue facing the superior surface, and
at least a distal end of a second protrusion is configured to penetrate and become lodged into the hard tissue at a second integration site of the second hard bone tissue facing the inferior surface.
