Normal variability in the age and first onset of ossification of the triquetral

The age and order of ossification of the triquetral, among the bones of the hand and wrist, were determined from serial radiographs of 108 males and 103 females of the Oxford Child Health Survey. Although the median ages of ossification agreed reasonably well with the mean ages reported by other authors, the distributions suggested that the former is the more appropriate statistic. The distributions of order of ossification were distinctly bimodal for both sexes because of the tendency of the triquetral to appear along with the epiphyseal centers. The triquetral appeared before the lunate in 184 children, after it in eight, and could not be sequentially distinguished in 19. Excluding these 19, triquetral sequence variability in the remaining was achieved, in 190, through alteration of its appearance relative to the epiphyseal centers and, in the other two through an alteration of the lunate appearance. Measures of median or average order of appearance are of very little value for the triquetral
