Analysis Of Clinical Efficacy Of Early Extracorporeal Shock Wave Therapy In The Treatment Of Non-or Delayed Union Of Fractures

Objective:To investigate the clinical efficacy of early extracorporeal shock wave therapy in the treatment of delayed union and nonunion of fractures. Methods:The clinical data of 57 patients with fracture delayed union or nonunion in our hospital from June 2010 to December 2013 were analyzed retrospectively,all patients were stable delayed union and nonunion of fractures.According to the time after the operation,28 patients for 3-9 months after the operation were selected as the group A;a total of 29 patients for more than 9 months after operation were selected as the group B.X-ray follow- ups were performed at every 3 months intervals,and the callus growth between the two groups were observed and compared. Results:Before the treatment and after the three courses of treatment,the callus core between the two groups had no statistical significance( P > 0.05).At the end of the first and second period of the treatment,there were statistically significant differences in callus score between the two groups(P <0.05).Therefore,the callus growth rate of the group A were significantly faster than the group B at the end of the first and second period of the treatment(P <0.05).There was no significant difference in the efficiency between two groups in three periods of treatment(P1=O.670;P2= 1.000;P3= 1.000).The differences were statistically significant in the cure rate between the two groups at the end of the first and second period of the treatment(P1=O.044;P2=0.047),but there was no significant difference in the third period of treatment(P3=0.190). Conclusions:Early extracorporeal shock wave therapy can reduce the incidence of delayed union or nonunion of fracture,it is worthy of clinical promotion.
