Open Versus Arthroscopic Assisted Treatment of Acute Acromioclavicular Joint Disruption Using Suture Button Device

Acromioclavicular (AC) joint dislocation is a common shoulder injury, especially among athletes and has an estimated incidence of 17% of all shoulder injuries and30%-50% of athletic shoulder injuries ,In most cases, these are caused by a direct fall on the ipsilateral shoulder tip. The indirect mechanism of injury with an extended arm is rare, The Rockwood classification system is currently used and based on the degree and direction of the disrupted anatomy of the AC joint.

Despite the high prevalence of this injury, there is no consensus about its optimal treatment. A variety of surgical procedures are described in the literature, such as an augmented suture with absorbable materials, stabilization with Kirschner (K)-wires in combination with or without additional wire loops, hook plates, or the Bosworth screw, but none can be considered the gold standard of operative AC joint stabilization, another treatment option was offered by the Tight Rope system, This technique was developed as a minimally invasive procedure in the management of AC dislocations. Because of its minimally invasive approach, it reduces soft tissue damage and yields better cosmetic results.9 Also, there is no need for reoperation to remove the hardware that might screws, or plates. Moreover, the complications of hardware failure, like breakage, dislocations, or bone fractures, are minimized
