目的：从生物力学角度探讨新型胫骨远端解剖钢板的力学性能。
方法：将12具新鲜湿润成人踝关节标本，随机区组分为4组(每组3具),3具正常胫骨作为对照(正常N组),9具造成胫骨远端不稳定性Pilon骨折，分别采用新型胫骨远端解剖钢板固定(A组)、重建钢板固定(B组)、三叶草钢板固定(C组),B、C两组为对照组，测试各组的远端轴向抗压强度、远端轴向刚度、扭转生物力学性能、胫距关节面接触特征。
结果：A组在胫骨远端不稳定性Pilon骨折的远端轴向抗压强度、远端轴向刚度、扭转生物力学性能以及胫距关节面接触特征上接近正常N组(P>0.05),优于B、C组(P<0.05).
结论：新型胫骨远端解剖钢板固定后比较牢固，能达到胫骨远端不稳定性Pilon骨折稳定、可靠的固定目的。 |

Abstract:
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 speciments),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.
Results: 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).
Conclusion: The new anatomic plate of distal tibia was relatively strong,which can reach effective and stable fixation for unstable distal tibial Pilon fracture. |
