[Biomechanical research in treating unstable Pilon fracture with anatomic plate of distal tibia].

Objective: To investigate the mechanical characteristics of new anatomic plate of distal tibia from view of biomechanics.

Methods: 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).
