(Reprinted with permission from Hughes and Jordan. 6, results in a variation of +10%, -14% in the cube of the cross-sectional area, and ultimate torsional strength. 4 results in an estimated variability in the torsional strength of ±24 %. These larger variations are the result of the tolerances on both the root diameter and the cannula itself. However, the larger root diameter of a cannulated screw accommodates this larger potential variability since for equivalent sizes it is considerably stronger than a solid cancellous screw, as discussed above.
