(a and b). Histological preparation of an osteotomized (a) and fractured (b) tibia 10 days after surgery. Alcian blue staining for cartilage to detect hyperblastic zones of chondrocytes. Diamonds indicate the proximal and anterior tibial side. Note the homogeneous pattern of cartilage around the fractured fibula compared to the osteotomized tibia in the same animal (a). Cavities correspond to the 1 mm wire diameter.
