摘要
Abstract
BACKGROUND:The creep mechanical properties of tibial fractures after fixation with intramedul ary nails, steel plates and external fixation support are rarely reported. <br> OBJECTIVE:To analyze the creep characteristics of tibial fractures with three internal and external fixation devices to provide biomechanical parameters for the clinic. <br> METHODS:We simulated tibial fractures with intramedul ary nails, steel plates, and external fixator. We performed axial compression creep tests on three sets of specimens on the electronic universal testing machine. <br> RESULTS AND CONCLUSION:The creep variables of intramedul ary nail fixation group were 0.22%, and the creep variables of steel plate fixation group were 0.34%in 7 200 s. In the external fixation group, creep variables were 0.42%in 7 200 s. The creep variables were larger in the external fixation group than in the plate fixation and intramedul ary nail fixation groups at 7 200 s (P<0.05). The creep deformation was greater in the plate fixation group than that of intramedul ary nail fixation group in 7 200 s (P<0.05). The results suggested that creep characteristics of the external fixation, plate fixation and intramedul ary nail fixation were al changed, but the changes were different.关键词
