The A-P and lateral radiographs of the representative case in each group at 8 weeks. Fracture lines remained and fractured femurs were not fused in the group I rats (a), whereas abundant callus formation was seen at the fracture site of group II (b).

Rats in group VI (f) showed complete bony union with matured callus
