27. A comparative in vivo ultrasonometric evaluation of normal and delayed fracture healing in sheep tibiae
OBJECTIVE: To compare normal and delayed bone healing by measuring ultrasound conduction velocity across the bone callus. METHODS: A model of transverse linear and 5 mm resection osteotomies of sheep tibiae was used. Fourteen sheep were operated on and were divided into two groups of seven according to osteotomy type. The procedure was performed on the rig

33. 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
