The authors studied the importance of the haematoma in the consolidationof fractures of long bones. It was performed an experiment in 50 Wistar rats thathad their tibiae fractures and stabilized with intramedullary wires. The haetoma wasaspired from the fracture site in the right limb whereas the left limbed served as control.The animals were sacrified in different periods of time, and the calli formed inthe samples were analysed in reltion to the radiological and microscopical aspects. Itwas observed a predominancy of fibrous tissue in the control limb and in the sampleswhere the haematoma was aspirated it was obtained a predominancy of cartilaginousand osseous tissue.
