【Abstract】 Polyglactin 910 woven mesh was subpe-riosteally placed over the tibial defect of 24 rabbits. After respective healing periods of 1. 2.4.8 and 13 weeks the animals were sacri-ficed. and 15μm H. E. stained undecalcifiecl sections were prepared and subjected to histo-logical analysis. The specimens showed that the mesh ?covered defect was thoroughly healed with new bone, whereas the control showed discontinuous new bone in the defect ( P < 0.001). The mesh was completely absorbed in 8 weeks postoperative. The results indicate that bone healing can be improved by the mesh because of its stabilization during the early stages of healing and its absorbability.更多还原
