4.2 Orthopaedic applications
Within orthopedics the following areas for Ca-aluminate based materials have been
identified; percutaneous vertebroplasty (PVP) and kyphoplasty (KVP), trauma and general
augmentation.
The benefits of the injectable ceramic biomaterials based on CA related to orthopaedic
applications are
During the surgical procedure (Engqvist et al, 2005, Lööf et al 2008)
High radiopacity allows for superior visibility of the cement during and increases the
probability to detect potential leakages during injection (See Figs. 13-14 below)
