1. A method of actively compressing bone segments comprising:
inserting a cannulated screw into a first bone segment and a second bone segment;
applying a longitudinal tensile stress to a cannulated body through deformation of a perforation formed through a sidewall of the cannulated body;
limiting the deformation of the perforation by engaging corresponding deformation limiting features formed in opposing sidewalls of the perforation;
releasing the tensile stress over a period of time; and
compressing the first bone segment and the second bone segment through said releasing the tensile stress.
