The ISAKOS Upper Extremity Committee (UEC) meets on a biannual basis for Closed Consensus Meetings. Each summit, a worldwide expert panel of surgeons and researchers convene for an in-depth discussion about a controversial topic. The purpose of this endeavor is to combine expertise and reach international consensus for the most appropriate management of various shoulder disorders. This booklet constitutes an integral part of the agreement encountered during these meetings. Section A provides a comprehensive review of the currently available Classifications and Outcome Scores for shoulder disorders, illustrating their potential pitfalls and limitations. Section B presents a summary of the Acromio-Clavicular Joint (ACJ) Consensus Summit, describing pioneering techniques to re-establish shoulder function after dislocation. Section C describes the current state of evidence of Rotator Cuff Disorders, providing novel theories regarding its underlying biomechanics and reconstruction techniques. The 2009-2013 ISAKOS UEC members hope the readers find this compendium an insightful update for daily shoulder management.
