Abstract

We reviewed the clinical results of the past 7 years in order to investigate the effect of extracorporeal shock wave therapy (ESWT) in nonunions of long bone fracture. Sixty-nine patients with 69 nonunions (22 femora, 28 tibiae, 13 humeri, 5 radii, and 1 ulna) were treated with extracorporeal shock waves. The technical parameters were 6,000 to 10,000 impulses at 28 kV (0.62 mJ/mm2 energy flux density) for the femur and tibia, 4,000 impulses at 24 kV for the humerus (0.56 mJ/mm2 energy flux density), and 3,000 impulses at 24 kV (0.56 mJ/mm2 energy flux density) for the radius and ulna. Sixty-six patients were followed up. The total successful rate of bony union was 75.4%. ESWT was successful in hypertrophic nonunions and seemed to have no evident effect in atrophic nonunions. We believe that extracorporeal shock wave therapy may be a good choice for nonunions of long bone fracture especially in hypertrophic nonunions.

Résumé

L’objectif de cette étude a été d’évaluer cliniquement les résultats observés sur les 7 dernières années lde a technique extracorporelle “schock wave” (ESWT) sur le traitement des pseudarthroses des os longs. Matériel et méthode : 69 patients présentant 69 pseudarthroses (22 fémurs, 28 tibias, 13 humérus, 5 radius et 1 cubitus) ont été traités selon cette méthode. Les paramètres techniques étaient de 6000 et de 10000 impulsions à 28 kV (062 mJ/mm2) pour le fémur et le tibia, 4000 impulsions à 24 kV pour l’humérus (0.56 mJ/mm2), 3000 impulsions à 24 kV (0.56 mJ/mm2) pour le radius et le cubitus. Résultats : 66 patients ont été suivis pendant au moins 12 mois. Le taux de consolidation a été de 75,4%. La ESWT est une technique qui permet de traiter une pseudarthrose hypertrophique alors qu’elle a peu d’effet sur les pseudarthroses atrophique. Conclusion : nous pensons que cette technique est une technique de choix pour les pseudarthroses des os longs spécialement lorsque ces pseudarthroses sont hypertrophiques.
