[Clinical study of reverse total shoulder arthroplasty versus open reduction and internal plate fixation for treatment of Neer three/four-part proximal humeral fractures in elderly].

Application of RTSA as the initial treatment of Neer three/four-part proximal humeral fractures in the elderly can achieve better rehabilitation of joint activity and lower risk of early reoperation, and improve the quality of life of elderly fracture patients. However, the difficulty of revision and the high cost of treatment require the surgeon to pay full attention and strictly grasp the indications.
