Effect of autologous stem cells on regenerated bone during distraction osteogenesis by Ilizarov technique in the radius of dogs. Histomorphometric analysis.

Purpose: To investigate by histomorphometry the distraction osteogenesis by Ilizarov technique in dog radius with the use of autologous stem cells in regenerated bone.

Methods: Ten dogs (20 radiuses) underwent the osteotomy of 20% of extension of their radiuses, and osteogenic distraction using the Ilizarov technique after this procedure at rate of 1mm per day divided into 0.5mm every 12 hours.
