Abstract OBJECTIVE: To evaluate the osteogenic effect of differing volumes of autogenous cancellous bone graft (ACBG) placed into partial cortical defects of the ulna. ANIMALS: 15 healthy, mature Beagles. PROCEDURE: Weekly radiographic views of defects were obtained over 8 weeks and were analyzed for bone density by use of radiographic optical densitometry. Histologic sections were obtained 8 weeks after surgery and were planimetrically evaluated for area of total, lamellar, and woven bone. RESULTS: Defects receiving 0.3 and 0.75 g of ACBG had rapid initial bone production, and dogs receiving 0.3 g of ACBG had faster bone ingrowth than did those receiving 0.1 g of ACBG or controls. Defects receiving 0.75 g of ACBG had a rate of bony ingrowth equal to 0.3 g of ACBG. There was no difference in the histomorphometric area fractions of total, lamellar, or woven bone between defects treated with 0.1 or 0.75 g of ACBG, and between grafted or control defects, 8 weeks after surgery. CONCLUSIONS: Overfilling a cortical defect with ACBG does not enhance early osteogenesis within the defect, and underfilling will delay the onset of osteogenesis within the defect. CLINICAL RELEVANCE: A volume of ACBG sufficient only to fill a cortical defect is required to obtain a clinical osteogenic effect from the graft.
