Abstract
A system for securing a prosthesis in a bone includes a reference anchor for insertion into a cavity of a bone to define a reference point during prosthesis implantation, the reference anchor including a body having a mating feature and a gripping projection for engaging an inner surface of the bone cavity. The system also includes a stem having a terminal end adapted to mate with the engagement feature of the reference anchor such that the stem is disposed at a desired position relative to the reference point.
Claims20
A system for securing a prosthesis in a bone, the system comprising:
- a reference anchor for insertion into a cavity of a bone to define a reference point during prosthesis implantation, the reference anchor including a body having a mating feature and a gripping projection for engaging an inner surface of the bone cavity;
- and
- a stem having a terminal end adapted to mate with the engagement feature of the reference anchor such that the stem is disposed at a desired position relative to the reference point.
A reference anchor and test system comprising:
- a reference anchor for deployment into a cavity of a bone to define a first reference point, the reference anchor including a body having a mating feature and an outer surface adapted to engage an inner surface of the bone cavity;
- a bone implant adapted to be releasably connected to the reference anchor, the bone implant including:
- a connector shaft having an elongate body extending from an actuation end to a coupling tip, the coupling tip being adapted to releasably mate with the mating feature of the reference anchor;
- a stem having an inner lumen, the stem being adapted to be disposed within the bone cavity and to receive the connector shaft within the inner lumen such that the coupling tip is mated with the reference anchor.
A method of anchoring a prosthesis to a bone at a desired location, the method comprising:
- inserting a reference anchor in a bone cavity;
- orienting the reference anchor in the bone cavity using a connector shaft;
- inserting a trial implant into the bone cavity;
- connecting the trial implant to the reference anchor;
- verifying that the reference anchor is at a desired position using the trial implant;
- disconnecting the trial implant from the reference anchor;
- inserting the prosthesis into the bone cavity;
- and
- securing the prosthesis to the reference anchor at the desired position.
