A device that allows for the predictable / guided anatomic drilling of claviclular tunnels for graft, suture, or combined graft / suture reconstruction of the AC joint is provided. The device simultaneously allows for larger clavicle tunnels which permit graft passage while providing protection, via stress shielding, of the bone between and adjacent to the bone tunnels. In this way, the surgeon is able to utilize anatomically placed clavicular tunnels large enough for graft passage (which reduces the mechanical failure rate of the reconstruction and most closely replicates normal anatomy) while reducing the risk of clavicle fracture, which has plagued other “anatomic reconstruction” techniques.
