ABSTRACT:
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.
