An awl suitable for both opening up a bone canal and for sizing that bone canal so as to obviate the use of a Charnley awl and the use of 4 to 5 distal reamers comprises (a) a tapered distal cutting head having a pointed first end, and a second end; and (b) a shaft attached to the second end, such that the shaft has a multiplicity of grooves calibrated so as to indicate the diameter of the isthmus of the bone canal. Also provided is a method of opening up a bone canal and of measuring the diameter of the isthmus of the bone canal with a single instrument.

Awls

The plug is made of a plastic material and acts as a cement barrier for openings produced by an operative procedure in medullated bones. The plug is clamped between the side walls of the opening of the bone by means of elastic flanges and prevents the bone cement from escaping downwards on insertion of an intramedullary stem or upon pressurization of the bone cement.
