目的：评估低强度超声对脊柱植骨融合的生物力学影响。

方法：40只12月龄大白兔制成腰椎双节段同侧横突间后外侧脊柱植骨模型，随机分试验组(B组)和对照组(A组).试验组用脉冲式超声刺激，6周后处死进行生物力学载荷、强度、刚度、扭转等测试比较。

结果：植骨融合6周时，试验组强度、刚度、扭矩和抗扭刚度、极限载荷均比对照组高6%～7%(P>0.05).

结论：低强度超声可以促进幼龄白兔脊柱植骨融合强度，加速骨折愈合。

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.

Conclusion: Lower intensity ultrasound can promote the speed and strength fusion of bone graft in young rabbits.

KEYWORDS:Lower intensity ultrasound Bone transplantation Spinal fusion Biomechanics
