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 j oining 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 configured for joining a first bone piece to a second bone piece, the device comprising:
- a first component comprising a wall portion, a first cavity defined in part by an interior surface of the wall portion, a first indentation extending into an exterior surface of the wall portion, at least one aperture extending through the wall portion from within the first indentation and to the first cavity, and a first stem portion for insertion into the first bone piece;
- a second component comprising a second stem portion for insertion into the second bone piece and an axially extending connector portion extending from the second stem portion and configured to be positioned within the first cavity, the connector portion including a plurality of second indentations extending into an outer surface thereof that are arranged along an axis of the connector portion;
- and
- a coupling member including at least one projection, the coupling member being positioned within the first indentation of the first component and extending through the at least one aperture such that the at least one projection is at least partially positioned within the first cavity,
- wherein, in a first orientation of the first and second components, the at least one projection is positioned at least partially within at least one second indentation of the connector portion to removably couple the first and second components.

A bone coupling device for coupling a first bone piece to a second bone piece, the device comprising:
- a first component comprising a wall portion, a first cavity defined in part by an interior surface of the wall portion, a first indentation extending into an exterior surface of the wall portion, at least one aperture extending through the wall portion from within the first indentation and to the first cavity, and a first stem portion for coupling with the first bone piece;
- a second component comprising a second stem portion for coupling with the second bone piece and an axially extending connector portion extending from the second stem portion configured to be positioned within the first cavity, the connector portion including a plurality of second indentations extending into an outer surface thereof that are arranged along an axis of the connector portion;
- and
- a coupling member including at least one projection, the coupling member being positioned within the first indentation of the first component and extending through the at least one aperture such that the at least one projection is at least partially positioned within the first cavity,
- wherein, in a first orientation of the first and second components, the at least one projection is partially retracted from the first cavity and abuts the outer surface of the connector portion, and
- wherein, in a second orientation of the first and second components, the coupling member portion is in a contracted state as compared to the first orientation such that the least one projection is positioned within at least one second indentation of the connector portion to removably couple the first and second components.
