title: [High-energy extracorporeal shock-wave therapy (ESWT) in the treatment of pseudarthrosis].
abstract: OBJECTIVE
  The success rate of high-energy extracorporal shock wave therapy in the treatment of non-unions in comparison to the "golden standard" surgery is still unclear.
  
  
  METHODS
  In a prospective study, 3000 impulses with an energy density of 0.6 mJ/mm2 were applied with an experimental device to the pseudarthrosis in 52 patients.
  
  
  RESULTS
  The mean duration of pseudarthrosis was 13 months. A mean of 2.5 surgical interventions had already been performed. Bony union was achieved in 52% of our patients after an average of 3.3 months. Failures especially were found in the atrophic type of pseudarthrosis as well as in congenital bone disorders like fibrous dysplasia or osteogenesis imperfecta. No serious complications were observed.
  
  
  CONCLUSIONS
  Even after numerous surgical interventions high-energy extracorporal shock wave therapy as a noninvasive method for the treatment of bony non-unions showed a fair success rate. A higher success rate can be expected by strict selection criteria.
