title: Ultrasonography in the evaluation of osteogenesis in fractures treated with Hoffmann external fixation.
abstract: The possibilities of ultrasonography demonstrating periosteal callus and osteogenesis at the fracture focus are described. Illustrative cases are presented and the advantages of this technique are discussed. It is emphasized that ultrasonography is a noninvasive technique that may be repeated as often as is necessary. It provides images of appositional periosteal callus much earlier than radiography, thus facilitating early evaluation of the treatment employed.
