Histological examinations (H&E stain) of the interfaces between bone and bone cement after 4 weeks of implantation. a, c P1TC2 and b, d P1TC3. New bone is indicated by arrows. For the biocomposite bone cement, the in vivo histological examinations demonstrated that a large number of pores existed in the interfacial area between the host bone and the bone cement, which afforded more space for bone ingrowth
