Reverse shoulder arthroplasty after failed megaprosthesis for osteosarcoma of the proximal humerus: A case report and review of literature.

The involvement of proximal humerus by Osteosarcoma is quite common, with the survival rates highly dependent on the staging of the tumor. Numerous salvage methods have been described but without any consensus. We present a case of a 17-year-old patient who had a wide excision of the tumor and underwent a mega prosthesis fixation, which underwent implant failure with the revised prosthesis subluxing. Finally, Reverse Shoulder Arthroplasty was done. Ten years follow up shows the success of the above. Salvage surgery in young patients yields good functional and cosmetic results. However, an insight into the complications associated with extended use of the mega prosthesis is needed. Prolonged survival after bone tumors is associated with surgical, medical and psychological challenges.
