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 adaptor. The method includes inserting the humeral stem to the humerus and connecting a male taper of the adaptor to a female taper of the head. For reverse arthroplasty, the method includes attaching the adaptor to the glenoid and the cup to the stem. For traditional arthroplasty, the method includes attaching the adaptor to the humeral stem and the cup to the glenoid. The method also includes articulating the head with the cup.

Shoulder implant assembly

A method and apparatus is disclosed for forming a mixed material. For example, two components of a bone cement may be positioned in the apparatus and mixed under vacuum. An increase in pressure on one side of a movable piston can move the material for ease of access and reducing voids in the mixed material.
