Shock wave is a kind of mechanical pulse pressing strong wave conducted by physical mechanism medium (air or gas). Mp-100 converts the impulse sound wave generated by aerodynamics into accurate ballistic shock wave, which is positioned and moved by the therapeutic probe.
Treatment of long bone nonunion with high energy extracorporeal shock wave (ESWT)
[Objective] to investigate the effect of high energy extracorporeal shock wave (ESWT) in the treatment of long bone nonunion. [Methods] 20 cases of nonunion after open reduction and internal fixation or plaster external fixation were selected, 2 cases of atrophic type and 18 cases of proliferative type. The shock wave intensity of ulna and radius 24 kV, humerus 26 kV, tibia and femur 28 kV, ulna and radius 1 500 times and humerus 3000 times, respectively, The femur and tibia were followed up for an average of 15.2 months. 8 cases healed after 3 months, 6 cases healed after 4 months, 3 cases healed after 5 months, and 1 case did not heal after 6 months. The average healing time was 3.9 months, [Conclusion] ESWT can be used as an effective treatment for nonunion and delayed union of long bone
