Assemblies for preparation of surgical sites

A method of preparing a surgical site comprising:

• positioning a first reaming assembly at the surgical site, the first reaming assembly comprising:
• a housing including a housing body extending along a first axis between proximal and distal end portions, and including a hood along the distal end portion;
• a first drive shaft;
• a first reaming head coupled to the first drive shaft, the first reaming head including first cutting teeth, the first drive shaft movable relative to the hood such that the hood at least partially surrounds the first cutting teeth;
• and
• a lock mechanism configured to set an axial position of the first reaming head relative to the hood with respect to the first axis;
• moving the first reaming head relative to the hood and then actuating the lock mechanism to set the axial position of the first reaming head according to a first reaming depth;
• rotating the first reaming head to establish a first recess in the bone, the first recess associated with the first reaming depth;
• positioning a second reaming assembly at the surgical site, the second reaming assembly comprising:
• a second drive shaft;
• and
• a second reaming head coupled to the second drive shaft, the second reaming heading including a second reaming portion having a distal face and second cutting teeth distributed about a perimeter of the distal face, the distal face free of any cutting teeth;
• and
• rotating the second reaming head to establish a second recess in the bone, the first recess extending inwardly from the second recess;
• and
• inserting an implant into the first and second recesses.
