A bone implant comprising:
- i. a head component for securing the implant into a bone, wherein the head component has a proximal end and distal end and is adapted along its entire length to be implanted entirely in the bone, wherein the proximal end has a long direction and a short direction both orthogonal to the length of the head component, and the head component is adapted for orienting the long direction parallel to a long axis of the bone;
- ii. one or more bone attachment components including a first bone attachment component, each independent of and separate from the head component for securing the implant into a bone, wherein each bone attachment component has a proximal end and a distal end and is adapted along its entire length to be implanted in the bone and includes an internally threaded bore hole for receiving a connector component;
- wherein the head component is further adapted to be secured to each of the bone attachment components with the connector components at the time of initial implantation of the bone attachment component and the head component into the bone;
- and
- wherein the first bone attachment component oriented at a tilt angle to the proximal end of the head component is secured to the head component at the tilt angle,
- wherein the tilt angle is an acute angle between the length direction of the head component and an axis of rotation of the first bone attachment component;
- and
- iii. an abutment adapted to be secured independently to the head component in an overlying relation to the head component;
- wherein each of the one or more bone attachment components has a distal neck with a convex collar surrounding the neck, wherein the neck has a lip region that surrounds the internally threaded bore hole of each of the one or more bone attachment components, and the neck has an external petal shaped locking feature incorporated on the lip region;
- the head component includes a bore hole for attaching the head component to one of the one or more bone attachment components using the connector component;
- wherein the neck of the bone attachment component inserts into the bore hole of the head component and the convex collar of the neck seats onto a matching concave proximal mating surface of the internal limiting flange of the bore hole of the head component while the petal shaped locking feature on the neck of each of the one or more bone attachment components extends beyond the limiting flange and couples with a matching petal shaped locking feature incorporated in the bore hole of the head component above the limiting concave flange.
