1. A sternal reconstruction system for securing parts of a sternum comprising:
a flexible cable having opposed first and second ends; an end fitting member attached to the first end of the flexible cable, the end fitting member having a cross-sectional dimension greater than that of the flexible cable; a fitting piece having a first end, a second end opposite the first end of the fitting piece, a length measured from the first end of the fitting piece to the second end of the fitting piece, and a first channel and a second channel each extending substantially parallel through the fitting piece along an entirety of the length from the first end of the fitting piece to the second end of the fitting piece; and a ferrule including a first end and a second end opposite the first end of the ferrule, the ferrule defining a hole that is sized to receive the flexible cable, the first end of the ferrule defining a first opening of the hole, the second end of the ferrule defining a second opening of the hole, the ferrule including a sharp edge positioned within the hole, such that the sharp edge is configured to cut the flexible cable during crimping of the ferrule onto the flexible cable; wherein the sternal reconstruction system defines an assembled configuration in which: 1) the end fitting member abuts the first end of the fitting piece at a first location aligned with the first channel, and 2) the ferrule is crimped to the flexible cable such that the first end of the ferrule abuts the second end of the fitting piece at a second location and the first opening of the hole faces and overlaps with the second channel.
