[Assessment of carpal bone maturation by imaging: an alternative to bone age determination or a complementary study?]

Radiographic evaluation of skeletal maturation with or without automated systems relies on the comparison between the radiographic appearance of portions of a child's skeleton and the standardized appearance in a comparable population of children. Assessment of skeletal maturation using image analysis of wrist computerized-assisted tomography is a quantitative method allowing for measurements of the volume of each carpal bone, the axis of inertia, and the mean bone density. Morphological modifications of carpal bones are characterized by quantitative data relating to the length of the axis of inertia and the volume. Imaging is a potentially useful method for carpal bone assessment during growth.
