ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect on increasing bone cement-bone interface micro-gomphosis intensity with bone cement oscillator.</p><p><b>METHODS</b>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 imaging (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.</p><p><b>RESULTS</b>Mechanics and CT test showed bone cement-bone interface micro-gomphosis intensity in oscillating group was significantly stronger than control group (P < 0.01).</p><p><b>CONCLUSION</b>Bone cement oscillator can significantly increase micro-gomphosis intensity of bone-cement interface, and reduce long-term aseptic loosening of artificial prostheses.</p>
