Assessment of bone healing using (Ti,Mg)N thin film coated plates and screws: Rabbit femur model.

Magnesium (Mg) based implants such as plates and screws are often preferred to treat bone defects because of the positive effects of magnesium in bone growth and healing. Their low corrosion resistance, however, leads to fast degradation and consequently failure before healing was completed. Previously, we developed Mg doped titanium nitrate (TiN) thin film coatings to address these limitations and demonstrated that <10 at% Mg doping led to enhanced mineralization in vitro.
