An Experimental Study in Promotion of Bone Healing by Autologous Red bone Marrow Grafting / 中华创伤杂志

To explore the significance of the autologous red bone marrow grafting alone in the process of bony healing, 30 New Zealand white rabbits were used and 10mm—long diaphysial defects were made on the bilateral same region of ulnae. On the left side of each animal 1. 5ml of bone marrow, aspirated from the autotogous greater trochanter, were injected into the defect as experiment group and on the right side 1.5ml of saline were injected into the defect as a control group. The speciments were observed by means of radioiso—tope, radiography, hostology and callus weight determination among 1～16 weeks in batches. These results demonstrated that the autologous red bone marrow grafting have definite effect on promoting bone healing.
