Abstract
Within medical age assessment practice, the indicator “medial clavicular ossification” constitutes crucial evidence capable of excluding age minority “beyond reasonable doubt” concerning age-disputed individuals doubtfully claiming children’s rights during legal procedures. Yet, one of its characteristics affects the morphological variability including a fair amount of downright peculiar appearances. As a result, inexperienced examiners are tempted to classify actually not-assessable formations according to the two established developmental typologies of Schmeling et al. and Kellinghaus et al. being at the same time the most frequent systemic error of age-related clavicular taxation. Since a respective overview appears missing, the study extracts not-assessable shape variants of the medial collar bone from a large sample of 2820 male borderline-adults as seen from thin-slice, sternoclavicular computed tomography. The two already highlighted configurations “more than one, medial, secondary ossification centres” and “medial metaphyseal concavity” are found as the most commonly encountered features impeding reliable delineation of staging criteria. In accordance with previous literature, it is emphasized that “qualified” rating of extremitas sternalis claviculae within age assessment practice presupposes “knowledge about the diversity of [its] anatomic shape variants.”
