Apparatus and methods for bone access and cavity preparation

Apparatus for preparing a bone cavity for implantation of an implant, the apparatus comprising:

• a drive shaft defining a radial direction and a longitudinal direction;
• a hub fixed to a terminal end of the drive shaft, the hub including a hub proximal end and a plurality of faces extending away from a flat, disc-shaped cap positioned at a hub distal end toward the hub proximal end, the faces defining a plurality of openings;
• a plurality of bone broaching members;
• and
• a plurality of supporting members, each of the supporting members supporting one of the bone broaching members and having a proximal end and a distal end, wherein each of the proximal ends is coupled to one of the bone broaching members;
• wherein:
• in operation, a distal end, and not a proximal end, of each of the supporting members aligns with the radial direction through one of the openings;
• each opening is positioned between a first of the faces and a second of the faces;
• and
• each of the faces follows a constant radius along the longitudinal direction.
