Resection of the proximal humerus for metastases and replacement with RPS prosthesis.

In the surgical treatment of metastatic lesions of the proximal humerus it is important to find solutions that eliminate pain and solve the mechanical problem in a short time and with reduced costs. In 90% of cases, intralesional curettage, freezing with liquid nitrogen and cement enhanced intramedullary instrumentation is capable of brilliantly solving the problems of these patients. When, instead, osteolysis involves the greater tuberosity and/or the joint region, resection of the proximal humerus followed by reconstruction with a modular prosthesis is indicated. Of those available on the market, the RPS system (LIMA) has features that make it equivalent to others, but at costs considerably lower. However, in reconstructions with prostheses, active abduction is significantly limited. A personal series of 20 patients is presented.
