Abstract
A system includes a first prosthesis. The first prosthesis may include a body extending along a length from a first side to a second and including a third side disposed between the first side and the second side. The body may include a pair of spaced apart rails between which a channel is defined. A stem and a first fixation element may extend upwardly from the third side. A method may include coupling the first prosthesis to bone.
Claims21
A system, comprising:
- a first prosthesis, the first prosthesis including a body extending along a length from a first side to a second and including a third side disposed between the first side and the second side, the body including a pair of spaced apart rails between which a channel is defined, wherein a stem and a peg project outwardly from the third side wherein the peg includes three circumferentially positioned, spaced-apart cutouts, each cutout being defined in an outer surface that extends the length of the peg, each cutout being sized to accept a portion of a corresponding prong that is integral with and laterally adjacent to each peg cutout, each prong being arranged to flex toward the peg so as to enter within the cutout when frictionally engaging a bone surface;
- and
- a second prosthesis sized and configured to be received within the channel defined by the body first prosthesis including a joint surface.
A method, comprising:
- coupling a first prosthesis to a bone, wherein the first prosthesis including a body extending along a length from a first side to a second and including a third side disposed between the first side and the second side, the body including a pair of spaced apart rails between which a channel is defined, wherein a stem and a peg project outwardly from the third side wherein the peg includes three circumferentially positioned, spaced-apart cutouts, each cutout being defined in an outer surface that extends the length of the peg, each cutout being sized to accept a portion of a corresponding prong that is integral with and laterally adjacent to each peg cutout, each prong being arranged to flex toward the peg so as to enter within the cutout when frictionally engaging a bone surface;
- inserting the first peg into a hole formed in the bone;
- and
- inserting the stem into an intramedullary canal formed in the bone.
1 more element
A system, comprising:
- a first prosthesis, the first prosthesis including a body extending along a length from a first side to a second and including a third side disposed between the first side and the second side, the body including a pair of spaced apart rails that form opposed side walls of a channel that extends inwardly from first side, wherein a stem and a first fixation element project outwardly from the third side.
A system, comprising:
- a first prosthesis, the first prosthesis including a body extending along a length from a first side to a second and including a third side disposed between the first side and the second side, the body including a pair of spaced apart rails that form opposed side walls of a channel that extends inwardly from first side and terminates at a rear wall that extends between the opposed side walls so as to be sized and configured to receive at least one of an artificial joint and articular surface, wherein a stem and a first fixation clement project outwardly from the third side.
