目的 评价骨水泥振动器对提高骨水泥-骨界面微嵌合强度的效果及临床意义.方法 取新鲜成猪股骨100根,随机分成6组;力学测试组:抗拉力实验组(A1)与对照组(A2)和抗压力实验组(B1)与对照组(B2)模型每组各20个;影像学测试组:实验组(C1)与对照组(C2)模型各10个.对模型进行力学及影像学检测,比较实验组与对照组骨水泥-骨界面的微嵌合强度.结果 力学及影像学测定显示实验组骨水泥-骨界面微嵌合强度均高于对照组,二者比较差异具有显著统计学意义(P＜0.01).结论 骨水泥振动器能显著提高骨水泥-骨界面微嵌合强度,对于减少人工假体远期无菌性松动具有一定的意义.
目的 評價骨水泥振動器對提高骨水泥-骨界麵微嵌閤彊度的效果及臨床意義.方法 取新鮮成豬股骨100根,隨機分成6組;力學測試組:抗拉力實驗組(A1)與對照組(A2)和抗壓力實驗組(B1)與對照組(B2)模型每組各20箇;影像學測試組:實驗組(C1)與對照組(C2)模型各10箇.對模型進行力學及影像學檢測,比較實驗組與對照組骨水泥-骨界麵的微嵌閤彊度.結果 力學及影像學測定顯示實驗組骨水泥-骨界麵微嵌閤彊度均高于對照組,二者比較差異具有顯著統計學意義(P＜0.01).結論 骨水泥振動器能顯著提高骨水泥-骨界麵微嵌閤彊度,對于減少人工假體遠期無菌性鬆動具有一定的意義.

Objective To evaluate the effect on increasing bone cement-bone interface microgomphosis intensity with bone cement oscillator.Methods One hundred femoral bones of adult pig were randomly divided into 6 groups:oscillating group(A1)and control group(A2)of anti-tensile force,oscillating group(B1)and control group(B2)of anti-pressure(n=20 in each group),oscillating group (C1)and control group(C2)of imageology(n=10 in each group).Mechanics and CT test was performed,micro-gomphosis intensity of bone cement-bone interface between oscillating group and control group was compared.Results Mechanics and CT test showed bone cement-bone interface micro-gomphosis intensity in oscillating group was significantly stronger than control group(P＜0.01).Conclusion Bone cement oscillator can significantly increase micro-gomphosis intensity of bone-cement interface,and reduce long-term aseptic loosening of artificial prostheses.
