title: Application of extracorporeal shock-waves in the treatment of pseudarthrosis of the lower extremity. Preliminary results.
abstract: Between January 1991 and January 1996, pseudarthroses of the legs were treated prospectively in 48 patients by application of high-energy extracorporeal shock waves with an experimental device. The mean duration of pseudarthrosis was 12 months. On average, 2.4 surgical interventions had previously been performed. A total of 3000 impulses with an energy density of 0.6 mJ/mm2 was applied to the pseudarthrosis. Bony union was achieved in 60.4% of our patients after an average of 3.4 months. Failures were found especially in the atrophic types of pseudarthrosis as well as in congenital bone disorders like fibrous dysplasia or osteogenesis imperfecta. No serious complications were observed. Even after numerous surgical interventions high-energy extracorporeal shock-wave therapy showed a fair success rate. A higher success rate of this non-invasive method for the treatment of bony non-unions may be expected by applying strict selection criteria.
