POSSIBLE DAMAGE TO THE RABBIT SCIATIC-NERVE BY THE APPLICATION OF EXTRACORPOREAL SHOCK-WAVES OF LOW OR MIDDLE ENERGY FLUX-DENSITY

Aim: The aim of the study was to evaluate the likeliness for periphera l nerve lesions following extracorporeal shock wave application. Mater ial and method: 82 rabbit sciatic nerves were randomized to undergo la w-energetic (0,08 mJ/mm(2)), middle-energetic (0,28 mJ/mm(2)) or no (c ontrols) shock wave therapy. After 1 to 28 days an independent neuropa thologist checked the specimen for signs of neural lesions. Results: O nly after 14 and 28 days vacuolic swelling of the axons was noted, som ewhat pronounced in the middle-energetic group. In no case was there a ny disruption of the nerve's continuity. We did not observe any neurap raxia. Conclusion: Shock wave application does not threaten peripheral nerve integrity in an animal model.
