Claim 9:
10. A compound medical implant for fixation and integration with hard bone tissues, the compound medical implant comprising:
a base member including a first portion and a second portion defining a void space, the first portion and the second portion each defined by opposed superior and inferior surfaces, configured to contact first and second hard bone tissue of a patient;
one or more rotational fixation 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 traverses through the void space defined by the first portion and the second portion,
the biocompatible rods are rotatable, and
the one or more rotational fixation mechanisms rotate around the biocompatible rods using the biocompatible rods; and

two or more sharp protrusions attached to the one or more rotational fixation mechanisms, the two or more sharp protrusions urged into the hard bone tissue by the one or more rotational fixation mechanisms,
a first sharp protrusion of the two or more sharp protrusions having a first proximal end attached to the one or more rotational fixation mechanisms and a first distal end, a second sharp protrusion of the two or more sharp protrusions having a second proximal end attached to the one or more rotational fixation mechanisms and a second distal end, the first and second distal ends configured to penetrate and become lodged into the hard bone tissue at an integration site,
wherein:
the first distal end of the first sharp protrusion is configured to penetrate and become lodged into the first hard bone tissue at the first integration site of the first hard bone tissue facing the superior surface, and
the second distal end of the second sharp protrusion is configured to penetrate and become lodged into the second hard bone tissue at the second integration site of the second hard bone tissue facing the inferior surface.
