Abstract
Provided is a bone joining device suitable for joining a first bone piece to a second bone piece. Also provided is a method of joining a first bone piece with a second bone piece in a living mammal. The method comprises inserting the above bone joining device between the first bone piece and the second bone piece.
Claims20
A bone joining device suitable for joining a first bone piece to a second bone piece, the device comprising
- (a) a female component, the female component comprising a first elongated stem portion comprising a first end, a first top opposite the first end, and an opening that extends axially from the first top toward the first end, the first elongated stem portion suitable for insertion from the first end longitudinally into a surface of the first bone piece;
- and
- (b) a male component, the male component comprising a second elongated stem portion comprising a second end and a second top, the second elongated stem portion suitable for insertion from the second end longitudinally into a surface of the second bone piece, and a connector extending from the second top, the connector comprising an elongated shaft, a top of shaft near the second top, and a distal end,
- wherein
- the connector and the second elongated stem portion are a single piece;
- the connector is capable of insertion into the opening in the first elongated stem portion and locking therein.

A tool for facing a bone surface and reaming a hole into an intramedullary canal of the bone, the tool comprising:
- an elongate shank having a proximal end and a distal end;
- the distal end terminating in a first shaping drill end terminating in a first point, the first shaping drill further comprising
- a plurality of first ridges having sharp edges immediately proximal to the first point;
- a first short shaft immediately proximal to the first ridges;
- a first shoulder wider than the first short shaft immediately proximal to the first short shaft;
- a first skirt having a first distal surface, wider than the first shoulder immediately proximal to the first shoulder having a flat distal surface;
- and
- a first cutout extending from the plurality of first ridges through the first short shaft, the first shoulder, and the first skirt, the first cutout having sharp lateral edges designed to cut through the bone as the tool is rotated and driven therein.
