ap radiographs of the glenohumeral joint of two patients showing how the greater tuberosity avulsion fragment after ASD reduces into a close to an anatomic position after closed reduction. From the Left to the Right: (A) radiograph after ASD, (B) check-up after closed reduction, (C) last follow-up. After closed reduction: GTI: 1.32, II: 1.07. At final follow-up GTI:1.15, II: 0.49. Formula: GTI=Rt/Rh; II=(Rt-Rh)/(Ra-Rh). ASD, anterior shoulder dislocation; GTI, greater tuberosity index; II, impingement index; Rh, Radius of a circle tangent to humeral articular surface; Rt, Radius of a circle tangent to the greater tuberosity; Ra, Radius of a circle tangent to the undersurface of the acromion.
