Clinical Effects of Large Segmental Bone Defects With 3D Printed Titanium Implant

Peking University Third Hospital20 enrolled

Overview

The investigators apply 3D printed titanium implant to treat bone defects. Without using bone grafts and growth factors, the investigators anticipate the titanium implant alone can help bone reconstruction.

The investigators treat large segmental bone defects caused by three reasons, including trauma, infection and tumor. In this study, polyporous 3D printed titanium implant is applied to reconstruct the bone defects and the investigators will follow up patients' function and bone regeneration.
