AIM:To introduce the construction of three dimensional model of anatomic distal radius memory compression connector(DRMC) and find out its memory biomechanical significance. METHODS:The finite element analysis software ANSYS 7.0 was used to establish three dimensional model by splitting the construction of the connector and reconstructing the part model. RESULTS:The constructed three dimensional DRMC model objectively reflected the real DRMC shape and biomechanical behavior,which could be undertake corresponding mechanics calculation. CONCLUSION:The construction of DRMC three dimensional model can provide exact model for treating the mechanics behavior of complexity pelvis fracture of acetabulum and the basic research of correlated mechanics.
