Abstract: Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.

Abstract: Provided is a method of resecting a humerus, including positioning a multi-part guide on the humerus, where the multi-part guide includes a support portion and a positioning jig; advancing at least two mounting pins through the support portion along diverging paths; removing the positioning jig; and resecting the humerus with reference to a cutting surface of the support portion.

Abstract: A humeral guide is provided that has a first portion or member configured to be positioned on a portion of a proximal humerus. The first portion or member can be configured to rest in a complementary manner on the portion of the proximal humerus. The humeral guide can be configured with apertures defining trajectories through bone, the pin trajectories being diverging in some case and in some cases being selected to enhanced support. A second portion or member and a third portion or member of the humeral guide are configured to be positioned on first and second lateral portions of the humerus distal to a location intended for resection, e.g., between an anatomical neck and a distal end of the humerus. The second and third portions or members or portions are configured to rest in a complementary manner on the first and second lateral portions of the humerus. The humeral guide can be configured to avoid soft tissue between a bone facing side and the humerus. The humeral guide can have a removeable jig portion.
