Proximal humerus fracture represents five to eight percent of all fractures and is twice as common in women than in men. Most cases of displaced fracture of the proximal humerus are treated surgically; it is probable that more cases are preferred to be treated surgically greater than required. The optimal treatment for these fractures remains controversial, but physicians have a tendency to treat via open reduction and fixation with angular locking plates or glenohumeral arthroplasty. We present a case of a 71-year-old woman with bilateral displaced proximal humeral fracture. Conservative treatment was initiated with two hanging casts, achieving radiological reduction on week one. After two additional weeks of casting, treatment continued with radiologic control and home physical therapy, ultimately an excellent functional outcome and adequate radiological reduction was obtained.   Even in bilaterally displaced proximal humerus fractures, conservative treatment can be an efficient option, reducing complications, reaching adequate functional results and acceptable radiographic reduction.​
