The degree of rotator cuff deficiency will be assessed using Goutallier classification and quantified as Cuff Deficiency Index (CDI), which directly provides biomechanical information for calculating deltoid forces used in finite element analysis. Von Mises stresses will then be analyzed in anatomically defined acromial zones (Levy zones I-III).",[48,49],"Rotator Cuff Injuries","Shoulder Fractures",[51,52,53,54,55],"reverse shoulder arthroplasty","finite element analysis","acromial fracture","rotator cuff","biomechanics","NOT_YET_RECRUITING","2026-05-06",{"date":59,"type":60},"2026-05-11","ACTUAL",{"date":62,"type":44},"2026-06-01",{"date":64,"type":44},"2027-03-05",{"name":5,"class":6},1]
