Abstract
An apparatus, system, and method may be used to replace a natural or artificial articular surface of a joint, and to repair a bone that is associated with the joint. In some embodiments, the apparatus, system, and method may include a joint replacement prosthesis with a prosthetic articular surface, a support structure securable to the bone, and a first attachment interface. The system may also include a bone plate with a bone engagement surface securable to the bone on either side of a fracture formed in the bone, or a damaged area of the bone. The bone plate may include a second attachment interface that is attachable to the first attachment interface of the joint replacement prosthesis in order to couple the bone plate to the joint replacement prosthesis.
Claims23
A system for repairing an end portion of a bone, the system comprising:
- an intramedullary nail comprising:
- a first attachment interface formed on a superior surface of the intramedullary nail;
- a bone plate comprising:
- a bone engagement surface that is securable to an exterior surface of the end portion;
- and
- a second attachment interface that is attachable to the first attachment interface of the intramedullary nail in order to couple the bone plate to the intramedullary nail;
- a first fastener configured to secure the bone engagement surface to the exterior surface of the bone;
- and
- a second fastener comprising a longitudinal axis and configured to secure the second attachment interface to the first attachment interface at any of a plurality of relative orientations;
- wherein:
- the bone engagement surface comprises a central aperture configured to reduce a weight and facilitate flexure of the bone plate;
- the bone plate is sufficiently thin to allow the bone engagement surface to be flexed into conformity with the exterior surface;
- and
- with the second attachment interface secured to the first attachment interface, the longitudinal axis of the second fastener is generally parallel to an axis of the bone.
An apparatus for repairing an end portion of a bone, the apparatus comprising:
- an intramedullary nail comprising:
- a first attachment interface formed on a proximal surface of the intramedullary nail;
- and
- a distal end opposite the proximal surface;
- a bone plate comprising:
- an arm comprising:
- a bone engagement surface that is securable to an exterior surface of the end portion;
- a first plurality of bone engagement features having a first plurality of holes, wherein the first plurality of bone engagement features is positioned such that, with the bone engagement surface secured to the exterior surface, the first plurality of bone engagement features extends anteriorly from the arm on an anterior side of the exterior surface;
- and
- a second plurality of bone engagement features having a second plurality of holes, wherein the second plurality of bone engagement features is positioned such that, with the bone engagement surface secured to the exterior surface, the second plurality of bone engagement features extends posteriorly from the arm on a posterior side of the exterior surface;
- and
- a second attachment interface that is attachable to the first attachment interface of the intramedullary nail in order to couple the bone plate to the intramedullary nail;
- and
- a plurality of bone screws insertable through the first plurality of holes and the second plurality of holes, and through the exterior surface to secure the arm directly to the bone;
- wherein the arm is shaped such that, with the second attachment interface attached to the first attachment interface, the arm extends towards the distal end of the intramedullary nail.
A system for repairing an end portion of a bone, the system comprising:
- an intramedullary nail comprising:
- a first attachment interface formed on a superior surface of the intramedullary nail;
- and
- a bone plate comprising:
- an arm comprising a bone engagement surface that is securable to an exterior surface of the end portion;
- an anterior bone engagement feature protruding anteriorly of the arm;
- a posterior bone engagement feature protruding posteriorly of the arm;
- and
- a second attachment interface that is attachable to the first attachment interface of the intramedullary nail in order to couple the bone plate to the intramedullary nail;
- wherein
- the anterior bone engagement feature comprises a first eyelet through which a first fastener is insertable to secure the bone plate to the exterior surface;
- the posterior bone engagement feature comprises a second eyelet through which a second fastener is insertable to secure the bone plate to the exterior surface;
- and
- the bone plate is sufficiently thin to allow the bone engagement surface to be flexed into conformity with the exterior surface.
A system for repairing an end portion of a bone, the system comprising:
- an intramedullary nail comprising:
- a first attachment interface formed on a superior surface of the intramedullary nail;
- and
- a bone plate comprising:
- an arm comprising a bone engagement surface that is securable to an exterior surface of the end portion;
- an anterior bone engagement feature protruding anteriorly of the arm;
- a posterior bone engagement feature protruding posteriorly of the arm;
- and
- a second attachment interface that is attachable to the first attachment interface of the intramedullary nail in order to couple the bone plate to the intramedullary nail;
- wherein:
- the arm comprises a gooseneck shape that extends superiorly over the end portion and then distally toward the second attachment interface;
- and
- the bone plate is sufficiently thin to allow the bone engagement surface to be flexed into conformity with the exterior surface.
