The complex roengenosonographic assessment of distraction osteogenesis in the process of polyfocal fragmental lengthening in patients with defects of long bones

The dynamical complex roentgenosonographic study of osteogenesis process during long bone defect filling is an optimal monitoring method which allows timely insertion of corrections in the process of transosseous osteosynthesis. The analysis of clinical cases (11 patients) demonstrated that use of the technology of multilevel fragmental lengthening in patients with defect-diastases of congenital etiology didn't provide the formation of proper distraction regenerate bones in the short-term period of single-staged rehabilitation. It's not reasonable to plan multilevel defect filling with simultaneous segmental lengthening in patients, who have defects of congenital etiology and obviously low reparaive activity of bone tissue. In patients with acquired defects of bone tissue additional osteotomy making and subsequent distraction can cause the intensification of reparative processes and the acceleration of organotypical reorganization of the distraction regenerate bone formed before.
