Figure 11.

Giemsa surface staining of the overview (40×) and the bone–cement interface (200×) of rat tibia after implantation of PMMA cement and SrBG/PMMA composite cement. Fibrous tissue is stained blue with Giemsa stain. (a,b) Rat tibia with implantation of PMMA cement at eight and 12 weeks (around the PMMA cement, a layer of soft tissue is seen in most parts of the bone–cement interface); (c,d) rat tibia with implantation of SrBG/PMMA composite cement at eight and 12 weeks (in many areas around the SrBG/PMMA composite cement, i.e. 30SrBG/PMMA cement, a good bonding to the bone is seen); (e,f) implant–bone interface with implantation of PMMA cement at eight and 12 weeks; (g,h) implant–bone interface with implantation of SrBG/PMMA composite cement at eight and 12 weeks. Red arrows indicated the implant–bone interface. (Online version in colour.)
