Low-Profile Tensionable AC Repair Technique
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 preassembled construct features two independent TightRope® sutures that attach to a Dog Bone button separately after passing the construct antegrade through a 3 mm bone tunnel.
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.
AC TightRope® Technique
AC joint separation can be effectively treated using the AC TightRope® technique. The Arthrex TightRope is a device consisting of two buttons - one round clavicle button and one oblong coracoid button. The buttons are joined by a continuous loop of #5 FiberWire®. This technique provides a simple, reproducible, minimally invasive technique for acute acromioclavicular joint stabilization which may enable a rapid return to activity for the acute injury.
Chronic AC Joint Reconstruction Technique
The Chronic AC Joint Reconstruction technique involves reconstruction of chronic AC joint separations anatomically using a tendon graft with backup mechanical fixation. The technique uses 5.5 mm x 8 mm PEEK Tenodesis Screws to achieve strong graft fixation in the clavicle that allows for the recreation of the conoid and trapezoid coracoclavicular ligament bundles. The graft is protected during the healing process by using a strand of FiberWire as backup mechanical fixation.
Twin Tail TightRope® Technique
In the ongoing evolution of treating AC joint injuries, the Twin Tail TightRope® features two independent clavicle buttons designed to help reduce and stabilize the AC joint for open, acute AC repairs. Like the AC TightRope® and GraftRope®, each clavicle button is independently joined to the coracoid button with a continuous loop of #5 FiberWire®. The twin tails help enable stabilization of the AC joint with a device that matches the normal coracoclavicular ligament anatomy.
