1. A screw trajectory guide for use in a shoulder procedure, the screw trajectory guide comprising: a guide body having a first surface shaped to mate with a glenoid baseplate, a second surface opposite the first surface, and a plurality of third surfaces recessed from the second surface and disposed between the first and second surfaces, the guide body including a plurality of protrusions extending from the first surface and shaped to be inserted into corresponding apertures of the glenoid baseplate;
the guide body including a plurality of channels, each channel extending from one of the plurality of third surfaces through a corresponding one of the plurality of protrusions to a distal end of the protrusion; wherein the third surfaces are oriented substantially parallel to the second surface, whereby when a drill is being advanced through one of the channels, the third surface associated with that channel comes into contact with a widened portion of the drill and stops the drill from being inserted farther into the channel than intended; and a guide channel formed through the guide body and extending from the first surface to the second surface; wherein the guide channel is internally tapered such that a secure connection can be provided between the guide and a correspondingly tapered component of the glenoid baseplate that is received within the guide channel.
