Summary
The treatment of delayed and nonunion of fractures by a single extracorporeal dose of high energy shock waves generated in a water medium and focused on the fracture site is reported. The shock waves break up sclerotic bone by producing microfissures and numerous bony fragments because of the difference in impedance between bone (and calculi) and soft tissues. Osteogenesis is stimulated and contributed to union in 70 out of 82 fractures within a reasonable time. Treatment was given as an outpatient with regional anaesthesia; there were no side effects or complications.
Résumé
Présentation d'une méthode nouvelle de traitement des pseudarthroses et des retards de consolidation, non invasive, non chirurgicale et pouvant être réalisée en une seule séance, sous anesthésie régionale, sans hospitalisation. Les auteurs utilisent des ondes de choc de haute énergie, générées en milieu aqueux, qui traversent les parties molles et atteignent le foyer de fracture. Du fait de la différence d'impédance entre l'os (ou les calculs) et les tissus mous, le choc brise les extrémités osseuses sclérosées, produisant des micro-fissures et de multiples petits fragments osseux, ce qui stimule l'ostéogénèse. La consolidation a été obtenue dans des délais raisonnables dans 70 cas sur 82. Il n'y a eu ni effets indésirables, ni complications.
