目的 评价骨水泥振动器对提高骨水泥-骨界面的整合效果及临床意义. 方法 取新鲜成猪股骨16根,随机分成两组,实验组(A组)与对照组(B组)模型各8根.猪股骨髓腔内应用骨水泥振动器进行骨水泥灌注后(对照组灌注骨水泥不经振动),对每组实验模型进行硬组织切片,每根股骨模型等距选取3个层面,HE染色后在体视显微镜下观察,经电脑Motic Med 6.0数码医学图像分析系统分析测量骨水泥渗透入松质骨腔的厚度,记为渗透厚度,将所得数值进行统计学分析,对比振动组与对照组的骨水泥灌注效果. 结果 体视显微镜下显示实验组骨水泥与骨小梁之间结合紧密,骨水泥在松质骨腔内充填均匀一致,骨水泥与骨小梁之间的结合紧密.对照组骨水泥向松质骨腔内渗透欠佳,在松质骨腔内充填不均匀.结果显示实验组骨水泥渗透厚度高于对照组,差异均具有统计学意义(P＜0.05). 结论 骨水泥振动器能够使骨水泥在骨髓腔内弥散更加均匀,能够促进骨水泥向骨小梁内渗透,从而增加骨水泥与骨小梁之间的微嵌合.
目的 評價骨水泥振動器對提高骨水泥-骨界麵的整閤效果及臨床意義. 方法 取新鮮成豬股骨16根,隨機分成兩組,實驗組(A組)與對照組(B組)模型各8根.豬股骨髓腔內應用骨水泥振動器進行骨水泥灌註後(對照組灌註骨水泥不經振動),對每組實驗模型進行硬組織切片,每根股骨模型等距選取3箇層麵,HE染色後在體視顯微鏡下觀察,經電腦Motic Med 6.0數碼醫學圖像分析繫統分析測量骨水泥滲透入鬆質骨腔的厚度,記為滲透厚度,將所得數值進行統計學分析,對比振動組與對照組的骨水泥灌註效果. 結果 體視顯微鏡下顯示實驗組骨水泥與骨小樑之間結閤緊密,骨水泥在鬆質骨腔內充填均勻一緻,骨水泥與骨小樑之間的結閤緊密.對照組骨水泥嚮鬆質骨腔內滲透欠佳,在鬆質骨腔內充填不均勻.結果顯示實驗組骨水泥滲透厚度高于對照組,差異均具有統計學意義(P＜0.05). 結論 骨水泥振動器能夠使骨水泥在骨髓腔內瀰散更加均勻,能夠促進骨水泥嚮骨小樑內滲透,從而增加骨水泥與骨小樑之間的微嵌閤.

Objective To evaluate effect of the bone cement oscillator on binding of the bone ce-ment-bone interface. Methods Sixteen femurs of adult pigs were divided into 2 equal groups at random:oscillating group (A) and non-oscillating group (B) as the control. After cement perfusion and oscillation treatment, 3 slices were sectioned from each femur specimen at the same intervals. The slices were stained with HE for observation of their fine structures under stereomicroscope. Penetration of bone cement into the bone trabeeula was analyzed by Motic Med 6. 0 software to compare the effect of oscillation between the 2groups. Results Stereomicroscopy revealed that cement bound closely with bone trabeeula at the interface and the bone cement was evenly distributed in the cancellous cavity in group A. In the control group, how-ever, the binding of bone cement with bone trabeeula was loose and the filling of cement in the cancellous cavity was uneven and discontinuous. Penetration of cement into bone interface was significantly deeper in the oscillating group than in the control group ( P ＜ 0.05) . Conclusion The bone cement oscillator can significantly increase binding of bone-cement interface.
