Summary
The aim of our study was to measure the volume of each carpal bone during childhood and adolescence by image processing from computed tomography (CT) scans, and to analyze the relationship between the eight carpal bones. Thirteen CT scans were performed in nine normal prepubertal, peripubertal and post-pubertal children, six boys and three girls, aged 5–14 years. Each scan was processed in order to extract the carpal bones. The volume was computed for each bone. There was a significant correlation between carpal bone volume and age (0.55<r<0.79), and a very strong correlation between the volume of a given carpal bone and the volume of all the others, whatever the age (0.87<r<0.99, p<0.01). Image processing is a potentially useful method for assessing bone maturation. The constant ratio between carpal bone volumes indicates that these bones interact with each other in wrist bone maturation
Résumé
Le but de notre étude était de mesurer le volume de chaque os du carpe au cours de l'enfance et de l'adolescence par analyse des images d'examens tomodensitométriques (TDM) du poignet, et d'analyser les relations entre les huit os du carpe. Treize TDM ont été réalisés chez 9 enfants en période prépubertaire, pubertaire et postpubertaire, 6 garçons et 3 filles, âgés de 5 à 14 ans. Les os du carpe ont été isolés les uns des autres sur chaque examen TDM et leurs volumes ont été calculés. Nous avons retrouvé une relation significative entre le volume des os du carpe et l'âge (0,55<r<0,79), et une relation très significative entre le volume d'un os du carpe et le volume des autres os du carpe, quel que soit l'âge (0,87<r<0,99, p<0,01). L'analyse d'image est une méthode intéressante pour évaluer la maturation osseuse. Le rapport constant entre le volume des os du carpe, quel que soit l'âge, semble indiquer que les os du carpe interagissent entre eux durant la maturation osseuse du poignet.
