a) Schema of right greater tuberosity malunion resulting in dysfunction of the rotator cuff because the length-tension relationship is altered. b) Post-operative anteroposterior radiograph of a right shoulder showing proximal humeral screw osteosynthesis of an unreduced greater tuberosity (A2 RCL (rotator cuff lesion)) and an inferior subluxation due to operative nerve block. c) Post-operative anteroposterior radiograph of the same patient after revision surgery that included arthroscopic hardware removal, arthrolysis, rotator cuff detachment, tuberoplasty with a burr, and repair with restoration of the normal length-tension relationship of the rotator cuff. Lateral acromioplasty should have been added.
