[Ultrasound scanning of the distraction regenerate in case of multilocus elongation of the fragments in patients with defects of long bones].

It was done ultrasound examination of distraction regenerates in patients with defect of bone tissue. The first group included 4 patients who had the size of congenital bone tissue defect 15.8±8.1 cm; the second group (3 patients) included posttraumatic defects with defect size 11.75±3.6 cm; the third group (4 patients) included posttraumatic defects with defect size 11±5.3 cm. It was discovered the particularities of distraction regenerate structural condition in case of low level of reparative osteogenesis. In the first group "ischemic" regenerate was characterized by slow formation of bone trabecules. In the second group "ischemic" regenerate had one or two hypo-echogenic cystic-like formations in the intermediate regenerate area. All patients of the third group had organotypic remodeling of the regenerate according to terms of distraction and fixation.
