The precise delineation of the size, shape, and location of an osseous
bridge is a critical step in the management of children who have a partial
growth arrest of the epiphyseal plate. Five children between the ages of
ten and fourteen years were diagnosed, with the aid of conventional
roentgenograms, as having a partial growth arrest. Magnetic
resonance-imaging studies were carried out to determine the exact size,
shape, and location of the osseous bridge. The information derived from the
imaging studies was essential for the determination of the appropriate
treatment and for the planning and undertaking of any operative
intervention.
