1. Introduction. The metabolic and regenerative properties of bone are disrupted when the tissue is damaged from trauma and disease. The dynamic and highly vascularised bone tissue has a natural regenerative ability to self-repair small defects and cracks; however, when defects are critical-sized, i.e., >2.5 cm [], the intervention of scaffolds is required.
