Abstract

Objective:To observe the effect of extracorporeal shock wave(ESW)for the treatment of bone nonunion and promotion of fracture healing.Methods:Twenty-two patients with fractures of delayed union and nonunion were treated with ESW.The X-ray of the fracture was taken every 4-6 weeks to observe condition of fracture healing.The second procedure of ESW was delivered to fractures while the X-ray did not show obvious callus formation at 12 weeks after the first treatment.The energy of ESW was 0.4 mJ/mm2 and the total pulse of each time was 1 600-2 400 times.Results:The time of callus formation in the patients was 4-12 weeks after treatment.Twenty cases had obvious callus formation,in which 17 cases achieved fracture healing in 3 to 6 months.Two patients of distal tibial fracture showed no effect after treatment.Conclusion:ESW has marked effect for treating bone nonunion and promoting fracture healing,which is promising in the future.
