Relationship of radial metaphyseal band width to stature velocity

A relatively radiodense metaphyseal band is present at the distal end of the radius in normally growing children. The width of this band is related to the velocity of stature growth. Though individual growth rates in height cannot be closely predicted from the width of the band in normal children and adolescents, in certain clinical conditions the band width may be a useful guide as to whether or not growth is proceeding normally. Examples are given of the effect of human growth hormone treatment on the band width in a case of isolated growth hormone deficiency and of the effect of thyroid treatment on the band width in a case of hypothyroidism.
