Abstract: Objective To explore the effect of different dosage of radial extracorporeal shock waves on fracture disunite and bone nonunions.Methods 42 patients were divided into 3 groups based on the different shock dosage, every group contained 14 patients and the shock dosages were 1000, 2000 and 3000 in Groups A, B and C respectively. All patients accepted the therapy for 3 times and followed up with X rays. Results 3 months after treatment, calluses were formated iin 2(14.7%), 8(57.1%) and 8(57.1%) patients in 3 groups respectively,which was lower in Group A than in Groups B and C (P<0.05), but there was no significant difference between Group B and Group C (P>0.05). 9 months after treatment, the corresponding cure rates were 28.6%, 85.7% and 78.6% in 3 groups respectively. The cure rate was lower in Group A than in Groups B and C (P<0.05), but there was no significant difference between Groups B and C (P>0.05). Conclusion The radial extracorporeal shock waves had dose-dependence and saturation for the shock dosage, 2000 is the optimal choice
