title: [Influence of the fusion of bone graft in spine of rabbit treated with lower intensity ultrasound].
abstract: OBJECTIVE
  To observe the influence of the fusion of bone graft in spine of rabbits which were treated with lower intensity ultrasound.
  
  
  METHODS
  Forty 12-month-old rabbits were made to be the models of bone graft in post-lateral between two homonymy processus transverses in lumbar, and divided into treatment group (B) and control group (A) randomly. Twenty rabbits of treatment group were treated with lower intensity ultrasound, killed after six weeks, and took radiological examination, measured indexs of biomechanics.
  
  
  RESULTS
  After 6 weeks of fusion of bone graft, treatment group were higher 6%-7% (P> 0.05) in strength, rigidity, torque andantitwist, maxload than that of control group.
  
  
  CONCLUSIONS
  Lower intensity ultrasound can promote the speed and strength fusion of bone graft in young rabbits.
