AC Dog Bone™ Button Technique

The precontoured, titanium Dog Bone button allows the use of knotless TightRope^® technology or multiple FiberTape^® sutures for AC joint reduction. The buttons are attached to the sutures independently—only suture material will be passed through the clavicle and coracoid tunnels—allowing the repair to be completed through smaller tunnels.

The low-profile AC implant and Dog Bone button combine to form a tensionable device optimized for the reduction and stabilization of acute and chronic acromioclavicular joint separations. This dual construct features two independent TightRope sutures preassembled into a clavicle insert and a Dog Bone button, which attaches to the suture loops separately after passing them antegrade through the 3 mm bone tunnels.
