The feasibility of Mg-1Sc alloy as orthopedic implant was studied by in vivo implantation into femur shaft of rabbit. The in vivo corrosion rate of Mg-154x Sc alloy was 0.60 +/- 0.06 mm.y(-1). Mg-1Sc alloy could maintain its structural and mechanical integrity for more than 5 months. Compared with Ti6Al4V alloy, Mg-ISc showed better osteogenesis. The corrosion products were mainly composed of Mg(OH)(2) , MgCO3 center dot 3H(2)O and calcium phosphate, which would not induce toxic effect. In general, the decent degradation rate in vivo and superior osteogenesis of Mg-1Sc alloy indicate that it may be a promising candidate for biodegradable orthopedic implants. (C) 2019 Elsevier B.V.
