Metal plates and surgical procedures used in this study. (A) Shown are representative Ti (VariAx Hand Locking Plate M, Straight plate 4 hole) (top) or Mg (bottom) plates used for internal fixation in a right tibial fracture model using six-month-old female Japanese white rabbits (7 per group). (B) A 5-cm incision was made on the medial portion of the lower limb and bone fracture was created in the right proximal tibia using a bone saw, without cutting through to the contralateral cortical bone. (C) Ti or Mg plates were used for each group and internal fixation for the right tibial fracture was performed. In both groups, four threaded 2.3 mm titanium screws were used for plate fixation in each rabbit.
