A stabilizer for use with a trackable surgical instrument can include a first member, a second member and a retaining member. The first member can have a first annular body portion and a first pair of legs extending therefrom. The first annular body portion can include a plurality of locating slots for engaging a selectively positionable portion of a surgical instrument. The second member can have a second annular body portion and a second pair of legs extending therefrom. The second annular body can engage a drive device of the surgical instrument. The first pair of legs can be telescopically coupled with and adjustable relative to the second pair of legs such that the first member can be axially adjustable relative to the second member. The retaining member can cooperate with at least one leg to retain the first member adjustably coupled to the second member.
