Ten adult mixed breed dogs without significant individual difference were made transverse fracture at bilateral iliopectineal crest 1.5cm above the dome of acetabulum, which were fixed with ATMF'S or steel plate respectively. The animals were sacrificed and specimens were procured at 2, 4, 6, 8 and 12 weeks after operation. Samples from the fracture gaps were investigated by histology of HE and Masson staining, image pattern analysis of new bone formation.
