Sternal Reconstruction with a Custom-Made 3D-Printed Titanium Neo-sternum Prosthesis After Resection for Primary Malignant Sternal Tumour.

Primary sternal tumours are rare. Most of them are malignant in nature. When localized, cure can be achieved by radical resection. However, it leaves a large bony defect in front of the heart that makes reconstruction a challenge. In this report, we describe our experience of sternal reconstruction using a custom-made 3D-printed titanium neo-sternum after en-bloc resection of sternal body and anterior ends of bilateral second to fifth ribs for chondrosarcoma.
