Universal broach system for humeral implants

A system for preparing a bone for receiving an anchor for a prosthetic implant, the system comprising:

• a first distal broach component comprising:
• a first broach body comprising a first superior surface;
• a first socket defined by the first broach body, the first socket extending into the first superior surface of the first broach body;
• and
• a first plurality of cutting spokes extending radially from the first broach body, each of the first plurality of cutting spokes separated by a first spacing such that an interval pattern is formed between adjacent cutting spokes;
• a proximal broach component comprising:
• a spacer body configured to attach to the first superior surface of the first broach body;
• and
• a plurality of spacer spokes extending radially from the spacer body, each of the plurality of spacer spokes separated by a second spacing equivalent to the interval pattern;
• an onlay implant comprising:
• a second attachment component configured to attach to the spacer body;
• a planar base attached to the second attachment component;
• and
• a first bearing component attached to the planar base;
• and
• an inlay implant comprising:
• a third attachment feature configured to attach to the first socket;
• a bowl-shaped base attached to the third attachment feature;
• and
• a second bearing component attached to the bowl-shaped base;
• wherein the spacer body has a thickness that is equal to a maximum gap thickness of the inlay implant.

• a plurality of spacer spokes extending radially from the spacer body, each of the plurality of spacer spokes separated by a second spacing equivalent to the interval pattern;
• and
• a second distal broach component different than the first distal broach component configured to prepare the bone for a second anchor, the second distal broach component configured for use with the proximal broach component alternatively to the first distal broach component, the second distal broach component comprising:
• a second broach body comprising a second superior surface;
• a second socket defined by the second broach body, the second socket extending into the second superior surface of the second broach body;
• and
• a second plurality of cutting spokes extending radially from the second broach body, each of the second plurality of cutting spokes separated by a third spacing equivalent to the interval pattern;
• wherein at least some of the second plurality of cutting spokes is longer than each of the first plurality of cutting spokes.
