title: [Study on the effect of bone-cement interface with bone cement oscillator].
abstract: OBJECTIVE
  To evaluate the effect on increasing bone cement-bone interface micro-gomphosis 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 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.
  
  
  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).
  
  
  CONCLUSIONS
  Bone cement oscillator can significantly increase micro-gomphosis intensity of bone-cement interface, and reduce long-term aseptic loosening of artificial prostheses.
