Abstract:
OBJECTIVETo investigate the mechanical characteristics of new anatomic plate of distal tibia from view of biomechanics.
METHODSTwelve 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.
RESULTSThe 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).
CONCLUSIONThe new anatomic plate of distal tibia was relatively strong, which can reach effective and stable fixation for unstable distal tibial Pilon fracture.
