Study of the Antipodal Capsular Fold and Its Potential Role in Antero-inferior Glenohumeral Instability

In schoulders instabilty, the soft tissue has not been the subject of histological studies, as has the "bare area" or zone devoid of cartilage, the exact role of which in glenohumeral biomechanics is unknown. This research is based on the hypothesis that the antipodal lesions are constant, underestimated and that an architectural disorganization at the capsulo-ligament level could contribute to the instability of the shoulder. The aim of this study is therefore to better characterize these lesions which could be the subject of a complementary stabilization procedure even in the absence of a humeral notch
