Relation of bone fracture nonunion with different energy grade of extracorporeal shock waves / 中国矫形外科杂志

[Objective]Acocording to the effect with different energy grade of extracorporeal shock waves to obtain the better energy of extracorporeal shock waves on treating the nonunion of rabbit radius fracture.[Method]The nonunion model was established in the radius of 32 standard New Zealand white female rabbits,they were' randomly divided into A1,A2,B1 and B2 4 groups.A1 and B1 were the right,A2 and B2 was the left.Treating effect,X-rays film and changs of tissue histology in each experimental groups were observed before and after treament by the shock waves with 0.3,0.4,0.5 and 0.6 mj/mm2 energy to analyze the statistical difference among the each experimental group.[Result]There was a significant difference(P
