Abstract Purpose Persistent acromioclavicular joint (ACJ) instability following high grade injuries causes significant symptoms. The importance of horizontal plane stability is increasingly recognised. There is little evidence of the ability of current implant methods to restore native ACJ stability in the vertical and horizontal planes. The purpose of this work was to measure the ability of three implant reconstructions to restore native ACJ stability. Methods Three groups of nine fresh-frozen shoulders each were mounted into a robotic testing system. The scapula was stationary and the robot displaced the clavicle to measure native anterior, posterior, superior and inferior (A, P, S, I) stability at 50 N force. The ACJ capsule, conoid and trapezoid ligaments were transected and the ACJ was reconstructed using one of three commercially available systems. Two systems (tape loop + screw and tape loop + button) wrapped a tape around the clavicle and coracoid, the third system (sutures + buttons) passed directly through tunnels in the clavicle and coracoid. The stabilities were remeasured. The data for A, P, S, I stability and ranges of A–P and S–I stability were analyzed by ANOVA and repeated-measures Student t tests with Bonferroni correction, to contrast each reconstruction stability versus the native ACJ data for that set of nine specimens, and examined contrasts among the reconstructions. Results All three reconstructions restored the range of A–P stability to that of the native ACJ. However, the coracoid loop devices shifted the clavicle anteriorly. For S–I stability, only the sutures + buttons reconstruction did not differ significantly from native ligament restraint. Conclusions Only the sutures + buttons reconstruction, that passed directly through tunnels in the clavicle and coracoid, restored all stability measures (A, P, S, I) to the native values, while the tape implants wrapped around the bones anteriorised the clavicle. These findings show differing abilities among reconstructions to restore native stability in horizontal and vertical planes. (300 words)

Acromioclavicular Joint Injury

Background: The treatment for acromioclavicular joint injury are debatable, there are fixation options include tension band wiring, AC joint reconstruction and hook plate These fixations are capable of providing a stable fixation, but controversy still exists that mentions the superiority of each of these fixationsPurpose: To compare biomechanical stability of 3 fixation include tension band wiring, double endo button, and hook plate to provide a scientific basis of the fixation.Methods: This research is an experimental in vitro. Using 27 acromioclavicular joints cadaver divided into three groups that performed tension band wiring fixation, double endo button and hook plate. Each fixation evaluated with 10, 20, 50 and 100 times repetitions with 100N traction force.Results: Tension band wiring gives the smallest displacement. In 10 times repetition average displacement of tension band wiring 0.056 mm (p = 0.000) compared to double endo button 1.622 mm and hook plate 0.867 mm. In 20 times repetitions, tension band wiring 0.1667 mm (p = 0,000) compared to double endo button 3.1778 mm and hook plate 1.1111 mm. In 50 times repetition, tension band wiring 0.3111 mm (p = 0.000) with double endo button 4.7778 mm and hook plate 1.3556 mm. In 100 times repetitions, tension band wire 0.556 mm (p = 0.000) while double endo button 5.4444 mm and hook plate 1.4556 mm.Conclusion: Tension band wiring have a good stability compared to double endo button and hook plate. But all of fixation provide stability for acriomioclavicular joint motion.
