Abstract:
Treatment of large segmental defects of long bone has always been a major challenge for the medical community. At present, the bone defects have been treated by autologous or allogeneic bone grafting, free vascularized fibula grafting, Masquelet technique, Ilizarov technique, cylindrical mesh technique and other methods. However, these technical steps are relatively complicated and their cycles are long so that it is difficult to repair the bone defects immediately after surgery and carry out early weight bearing and functional exercise. In recent years, customized 3D printed microporous titanium (tantalum) prostheses have provided a safe and feasible treatment method for repair of these large bone defects. 3D printed microporous titanium (tantalum) prosthesis can accurately reconstruct the anatomical shape of a bone defect, and simultaneously provide stable biomechanical support for the overall bone structure by its mechanical strength of titanium alloy, demonstrating obvious advantages in the repair and regeneration of bone defects. This paper reviewed the characteristics, design requirements, mechanical properties, vascularization challenges and clinical applications of 3D printed microporous titanium (tantalum) prosthesis, and looked ahead to the future development of this new 3D printed prosthesis.
