Claim 0:
1. A bone fusion device for use with bones of an upper extremity, the bone fusion device comprising:
a fusion implant configured for implantation into a cavity spanning at least two adjacent bones, the fusion implant including:
a body having a first end, and
a second end substantially opposing the first end;
the first end including an attachment mechanism comprising a first tip surface and a second tip surface at a longitudinal end of the first end, the first tip surface and the second tip surface connected to a body surface of the body angled relative to an axis of the implant such that the first tip surface and the second tip surface have different longitudinal dimensions to allow a user to couple the implant with an instrument in a predefined first orientation different from a second undesired orientation;
the body having a substantially smooth outer surface and defining a longitudinal axis, the body including at least two non-threaded apertures extending laterally through the body from a first side of the body to a second side of the body and at least two internally threaded apertures including a first thread lead extending laterally through the body from a third side of the body to a fourth side of the body, the at least two threaded apertures including a first threaded aperture proximate the first end, and a second threaded aperture proximate the second end and angled with respect to the longitudinal axis of the body such that the second threaded aperture defines an axis that angles away from the second end as it extends from the third side to the fourth side.
