Interconnected implants and methods

An apparatus for replacing a natural or artificial articular surface of a hip joint and for repairing a greater trochanter of a femur associated with the hip joint, the apparatus comprising:

• a hip prosthesis comprising:
• a neck that is securable to the femur associated with the hip joint;
• an arm coupled to the neck;
• a prosthetic ball comprising an articular surface, wherein the prosthetic ball is couplable to the arm of the hip prosthesis;
• and
• a first attachment interface formed on a superior surface of the hip prosthesis;
• a bone plate comprising:
• a bone engagement surface that is securable to the greater trochanter of the femur on either side of a fracture formed in the greater trochanter of the femur;
• and
• a second attachment interface that is attachable to the first attachment interface of the hip prosthesis in order to couple the bone plate to the hip prosthesis;
• and
• a fastening system configured to engage the second attachment interface with the first attachment interface and couple the bone plate to the hip prosthesis;
• wherein:
• the second attachment interface of the bone plate is attachable to the first attachment interface of the hip prosthesis:
• at any of a first plurality of relative orientations about a first axis;
• and
• at any of a second plurality of relative orientations about a second axis orthogonal to the first axis;
• the first attachment interface comprises an outwardly protruding feature having a first round shape with a first radius;
• the second attachment interface comprises a recess having a second round shape with a second radius;
• and
• the second generally semispherical shape of the recess is complementary to the first generally semispherical shape of the dome.

A method of replacing a natural or artificial articular surface of a joint and repairing a bone associated with the joint, the method comprising:

• coupling a joint replacement prosthesis to the bone associated with the joint;
• replacing an articular surface of the joint with a prosthetic articular surface of the joint replacement prosthesis coupled to the bone associated with the joint;
• coupling a bone plate to the joint replacement prosthesis;
• securing the bone plate proximate a damaged area of the bone to facilitate repair of the damaged area of the bone associated with the joint;
• and
• with a fastening system, engaging a second attachment interface of the bone plate with a first attachment interface of the joint replacement prosthesis to couple the bone plate to the joint replacement prosthesis:
• at any of a first plurality of relative orientations about a first axis;
• and
• at any of a second plurality of relative orientations about a second axis orthogonal to the first axis;
• wherein:
• the first attachment interface comprises an outwardly protruding feature having a first round shape with a first radius;
• the second attachment interface comprises a recess having a second round shape with a second radius;
• and
• the second generally semispherical shape of the recess is complementary to the first generally semispherical shape of the dome.
