Novel Sternal Reconstruction with Custom Three-Dimensional–Printed Titanium PoreStar Prosthesis

Abstract

Resection of sternal tumors can leave large defects, which exposes major mediastinal structures, and can affect respiratory mechanics. If feasible, resection is potentially a complex reconstructive challenge to restore normal and functional anatomy using conventional techniques. We report the first Australian use of a three-dimensional–printed titanium and PoreStar prosthesis in a 39-year-old woman for reconstruction after major surgical resection of the sternum for metastatic breast cancer. The patient successfully underwent excision of the sternum and costal cartilages as well as implantation of the prosthesis. We conclude that three-dimensional–printed prostheses are technically feasible to deliver excellent cosmetic result.
