The Effect of Unfocused Extracorporeal Shock Wave Therapy on Bone Defect Healing in Diabetics

Aim: The purpose of this study was to evaluate the effect of the unfocused extracorporeal shock wave therapy (ESWT) on healing of mandible ramus defects in diabetic rats. Material and method: Forty male Wistar albino rats were used in the experiment. All animals were randomly divided into 2 main groups, nondiabetic and diabetic. Critical-sized defects were created on ramus in all rats. ESWT was performed to half of rats in each group at 3 sessions after surgery. Animals were euthanized at either fourth or eighth week. Stereological and radiologic examination was performed. Data were statistically analyzed by one-way variance analysis and Tukey post-hoc test. Results: Hounsfield Unit (HU) values were higher in D−E+ group than D−E− group in both 8-week and 4-week groups (P > 0.05). In both 4-week and 8-week diabetic groups, higher value was observed when compared with nondiabetic groups (P > 0.05). According to stereological results, in 4-week groups, there was a higher NB, CT, and NV volume in D−E− group than D−E+ group and in D+E− group than D+E+ group. These results are similar for the 8-week groups except NV volume. Conclusion: It was found that ESWT application has no positive effect on the healing of critical-sized bone defects in nondiabetics whereas promising effects in diabetics were observed.
