Abstract
We compared the result of proximal humerous and distal humerous malignant tumors in operation with Howmedica Modular Resection System (HMRS) prosthesis. This report was based on clinical results of 2 patients with malignant bone tumors of humerus who were treated with HMRS by the authors. The patient in case 1, a 51 year-old man with chondrosarcoma of the right proximal humerus, received wide resection and reconstruction with HMRS prosthesis. Four months after surgery, the prosthesis was removed because of rupture of the wound by foreign body reaction. And vascularized fibula graft was performed. The patient in case 2, a 76 year-old man with matastatic bone tumor of the right distal humerus, received marginal resection and reconstruction with HMRS prosthesis. At the last follow-up, seven months after surgery, symptoms of inflammation and infection were not found and the results were good.
