Balloon Kyphoplasty is a minimally invasive surgery, which has acquired great importance recently for treating compressive bone fractures by balloon inflation and PMMA cement injection (Achatz et al. 2017). The PMMA cement is subjected to challenging body environment once it is injected into the cancellous bone. The PMMA and porous cancellous bone interface experiences complex in vivo 3 D loading which causes compressive and fracture configuration. Many researchers have worked intensively on the mechanical analysis of the bone and PMMA cement. However, works reported on mechanical analysis of bone and PMMA cement interface were limited and none when it comes to fracture analysis.
