ABSTRACT
<p><b>OBJECTIVE</b>To investigate the mechanical characteristics of new anatomic plate of distal tibia from view of biomechanics.</p><p><b>METHODS</b>Twelve fresh adult moist ankle specimens were randomly divided into four block groups (every group had 3 specimens), 3 tibial specimens as a normal control (normal group N), 9 specimens were resulted in unstable distal tibial Pilon fracture. Using steel plate fixation with a new anatomic distal tibial plate (group A), reconstruction plate (group B), clover plate (group C). Group B and group C as control group to test the remote axial compressive strength, remote axial stiffness, reversing biomechanical properties, contacted characteristics of the tibial astragaloid articular surface.</p><p><b>RESULTS</b>The remote axial compressive strength, remote axial stiffness, reversing biomechanical properties, contacted characteristics of tibial astragaloid articular surface the in distal tibial Pilon fracture instability of group A were near normal group N (P>0.05). Group A was best than group B and C (P<0.05).</p><p><b>CONCLUSION</b>The new anatomic plate of distal tibia was relatively strong, which can reach effective and stable fixation for unstable distal tibial Pilon fracture.</p>
