In hypertrophic nonunions the fibrous or fibrocartilaginous tissue between the bone ends is capable of biologic reaction, and gradual distraction acts as a stimulus on this tissue with preserved osteogenic potential. From 1986 to 1991, 43 non-infected hypertrophic nonunions of long bones were treated by simple distraction. Consolidation was achieved in all cases and the deformities, particularly length discrepancies, were corrected as well. The results obtained in this series confirm that the fibrous tissue of the nonunion site acts in a way similar to the 'interzone' located between the two ends of corticotomy when bone lengthening is performed.
