1. A temporary cement spacer, comprising:
a spacer core including:
a rod defining a central axis of the spacer core and having a proximal rod end and a distal rod end opposite the proximal rod end along the central axis, the rod further defining an outer rod surface extending between the proximal rod end and the distal rod end;
a locking component defining a distal locking end and a proximal locking end opposite the distal locking end along the central axis, the distal locking end attached to the rod at the proximal rod end, the locking component further defining at least one locking bore extending through the locking component in a radial direction with respect to the central axis, the at least one locking bore configured to receive a locking screw; and
a cap defining a proximal cap end and a distal cap end opposite the proximal cap end along the central axis, the proximal cap end attached to the distal rod end; and
a cement coating surrounding at least a portion of the outer rod surface, the cement coating comprising a mixture of a cement material and one or more antimicrobial agents,
wherein the cap is configured to define a leading end of the temporary cement spacer during implantation.
