Long-term Review of a Cohort of Arthroscopic Bankart Interventions

Study Overview
=================
Brief Summary
-----------------
Recurrent instability is the most common chronic shoulder pathology of the young and athletic patient. It is a source of functional, sporting and professional disability, and a permanent apprehension to the use of the affected shoulder. Surgical treatment has been proposed for a long time by the reintegration of the labrum (intervention of Bankart) then by the making of an osteo-muscular stop (intervention of Latarjet). Like in many domains, surgical techniques have evaluated towards the search for endoscopic alternatives to open surgery, more deleterious. Bankart's intervention has been performed arthroscopically since the 1980s and remains the majority intervention in the United States. However, its success rate never reached that of open techniques, Bankart and Latarjet. Surgeons therefore sought the predictors of these failures in order to define the limits of the indications for arthroscopic Bankart intervention. The determination and use of the preoperative instability score (Instability Severity Index Score : ISIS) described by Balg and Boileau is one of the ways to clarify these indications. The aim of this study is to prospectively establish the values of the ISIS score to obtain an acceptable recurrence rate of long-term instability
