Abstract:
Background: Repair of bone defects is challenging for reconstructive and orthopedic surgeons. In this study, we aimedto histomorphometrically assess new bone formation in tibial bone defects filled with octacalcium phosphate (OCP),bone matrix gelatin (BMG), and a combination of both.Methods: A total of 96 male Sprague Dawley rats aged 6-8 weeks weighing 120-150 g were randomly allocatedinto three experimental (OCP, BMG, and OCP/BMG) and one control group (n=24 in each group). The defects inexperimental groups were filled with OCP (6 mg), BMG (6 mg), or a combination of OCP and BMG (6 mg, 2:1 ratio).No material was used to fill the defects in the control group and the defect was only covered with Surgicel. Sampleswere taken on days 7, 14, 21, and 56 after the surgery. The sections were stained with hematoxylin-eosin (H&E) andassessed using light microscopy.Results: In our experimental groups, bone formation was started from the margins of the defect towards the centerwith an increasing rate during the study period. Moreover, the formed bone was more mature. Bone formation in ourcontrol group was only limited to the margins of the defect. The newly formed bone mass was significantly higher inthe experimental groups (P=0.001).Conclusion: OCP, BMG, and OCP/BMG compound enhanced osteoinduction in long bones.Level of evidence: III
