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/mm(2) energy flux density) for the femur and tibia, 4,000 impulses at 24 kV for the humerus (0.56 mJ/mm(2) energy flux density), and 3,000 impulses at 24 kV (0.56 mJ/mm(2) 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.
