In eight clinically healthy dogs, a midshaft diaphyseal defect of 2 cm was created in the right radius ulna. This gap was maintained by fixing a four hole sherman bone plate on the radius. In four dogs, the gap was filled with autogenous cancellous bone grafts (2-5 mm in diameter) harvested from the proximal end of the tibia (group 1). In the remaining 4 dogs, the fracture gap was filled with autogenous cortical bone fragments (ACBF) of 2-5 mm diameter made from the same 2 cm piece of bone removed from the radius. While comparing various clinical observations, it appeared that healing of the wounds and bearing of the weight on the grafted limb in dogs subjected to ACBF graft were similar to those given autogenous cancellous bone graft. In radiographs, taken on the 30th day in group 1, a fairly good amount of callus was found emerging from fracture ends but the whole of the bone graft area was not covered by bony density even on the 60th day. In group 2 (ACBF), 45th day radiograph revealed that the callus from the fracture end was mixing up with the cortical bone fragments, and at the 60th day, the callus was clearly found invading the cortical bone fragments grafted in the fracture gap.
在8只临床健康的犬中，于右侧尺桡骨骨干中段制造了一个2厘米的骨缺损。通过在桡骨上固定一块四孔的谢尔曼骨板来维持该间隙。在4只犬中，该间隙用从胫骨近端采集的自体松质骨移植物（直径2 - 5毫米）填充（第1组）。在其余4只犬中，骨折间隙用由从桡骨取下的同一段2厘米长的骨制成的直径2 - 5毫米的自体皮质骨碎片（ACBF）填充。在比较各种临床观察结果时，发现接受ACBF移植的犬的伤口愈合情况以及移植肢体的负重情况与接受自体松质骨移植的犬相似。在第1组第30天拍摄的X光片中，发现骨折端有相当多的骨痂出现，但即使在第60天，整个骨移植区域也未被骨密度覆盖。在第2组（ACBF）中，第45天的X光片显示骨折端的骨痂与皮质骨碎片混合在一起，并且在第60天，明显发现骨痂侵入了移植到骨折间隙的皮质骨碎片中。
