We asked how bone fragment displacement could influence on callus biomechanical parameters and biological quality in bone elongation process. A distraction osteogensis 20mm by Ilizarov method was created in 21 sheep metatarsus. The bone fragments were externally fixed with a specially designed ring actuator-driven external fixator. Two experimental groups witch eight sheep each received either 1 or 2mm axial displacement of bone fragments. Mechanical stimulation was applied over 30 days for lh per day with a frequency of 1 Hz. The third group of five sheep served as a control group only bone elongation applied without actively induced displacement. Eight weeks postoperatively the sheep were killed and the elongated bones were investigated radiologically, biomechanically and histomorphologically. Biomechanical tests were determine callus flexural rigidity. Histological analysis made possible biological quality of callus evaluate.
