Abstract:
[Objective]To explore the effect of continuous physiological osteogenic stress on the bone healing of canine iliopectineal crest.[Method]Ten adult mixed breed dogs without significant individual difference were made transverse fracture at bilateral iliopectineal crest 1.5 cm above the dome of acetabulum,which were fixed with ATMFS 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.[Result]The formation of cartilaginous tissue and the maturity of cortical and trabecular bone and collagen fibers of ATMFS sides were earlier than that of steel sides obviously.There was significant difference of the integrated optical density (IOD) of new bone formation between two groups (P
