Simultaneous 3D Assessment of Glenohumeral Shape, Humeral Head Centering, and Scapular Positioning in Atraumatic Shoulder Instability

All active and passive stabilizers need to be analyzed in patients with atraumatic instability because the magnitude of alteration varied widely among individuals. Different combinations of alterations of the stabilizers were found. The presented technique allows for in vivo identification of the specific alterations. This is necessary for a better understanding of individual pathomechanics and for initiating a specific causal treatment.
