A drill guide comprising:
- a handle, and
- a sleeve having a first end attached to one end of said handle, said sleeve comprising:
- a first bore,
- a first ferrule dimensioned for demountable insertion into one end of said sleeve and having a second bore dimensioned to receive therethrough an instrument having a particular width, and
- a second ferrule which is demountably attached to an end of said first ferrule, said second ferrule extending from an end opposite said one end of said first bore,
- wherein said exposed end of said second ferrule has markings on an outer surface thereof indicating a penetration depth of said instrument inserted through said second bores of the attached pair of ferrules.
