Abstract
An implant assembly and associated method for selectively performing reverse and traditional arthroplasty for a shoulder joint that includes a humerus and a glenoid. The implant assembly may include a head, a cup, a humeral stem and an adapter. The method includes inserting the humeral stem to the humerus and connecting a male taper of the adapter to a female taper of the head. For reverse arthroplasty, the method includes attaching the adapter to the glenoid and the cup to the stem. For traditional arthroplasty, the method includes attaching the adapter to the humeral stem and the cup to the glenoid. The method also includes articulating the head with the cup.
Claims21
An implant assembly for a shoulder joint having a humerus and a glenoid, the assembly comprising:
- a head bounded by a convex surface and a planar base, the base including a female taper;
- a humeral stem configured to be inserted in the humerus;
- a cup having a concave surface configured to articulate with the convex surface of the head;
- and
- an adapter including a tray and a male taper, the tray configured to be attached to said cup, wherein the adapter is configured to connect the cup to the glenoid when the head is connected to the humeral stem, and wherein the adapter is configured to connect the cup to the humeral stem when the head is connected to the glenoid.
An assembly of implant components for a shoulder joint having a humerus and a glenoid, the assembly comprising:
- a humeral stem;
- a head having a convex surface;
- a cup configured to articulate with the convex surface of the head;
- and
- an adapter being configured to connect the head to the glenoid when the cup is connected to the humeral stem, and wherein the adapter is configured to connect the head to the humeral stem when the cup is connected to the glenoid.
An implant assembly for a shoulder joint having a humerus and a prepared glenoid, the assembly comprising:
- a first member defining a convex articulating surface;
- a second member defining a concave surface configured to articulate with the convex articulating surface;
- and
- a first adapter configured to be attached to said second member, wherein said first adapter is configured to connect said second member to the prepared glenoid when said first member is connected to the humerus, and wherein said first adapter is configured to connect said second member to the humerus when the first member is connected to the prepared glenoid.
