A method for utilizing a sternal closure device for securing and retaining longitudinally divided halves of a sternum, the device having two sets of anterior and posterior longitudinally extended brace members with brace joining mechanisms extending through the sternal halves to join the anterior brace members to the posterior brace members, such that the sternal halves are compressed between the anterior and posterior brace members, and transverse bridging members that laterally connect the two sets of brace members, with securing mechanisms to retain the two sets of brace members in a contracted configuration with the sternal halves in abutting relation.
