Expandable hip stem implants, systems, and methods of implanting a hip stem during a hip arthroplasty are provided. The implant may include a proximal body having a neck terminating at a free end, a distal stem having a proximal portion coupled to the proximal body and a distal portion, and a plurality of expandable bodies aligned around the distal stem. The plurality of expandable bodies have a collapsed configuration and an expanded configuration such that the plurality of expandable bodies expand radially outward away from one another.

Tibial implants, instruments, systems, and methods of implanting a tibial tray during a knee arthroplasty. The inserter instrument may include a main body with a pair of fixed posterior tabs, a moveable anterior tab body with an anterior tab, and a rotatable shaft for controlling movement of the anterior tab body. When the shaft is rotated, the anterior tab body is translated into an expanded position to lock the inserter to the tibial tray, thereby providing precise positioning of the tibial tray during implantation.
