Abstract

AbstractThe craniocervical junction (CCJ) of humans and other vertebrates is a developmental restless region. Due to complex phylogenetic and ontogenetic processes, many anatomical variations can be found in that transitional area. Therefore, newly described variants must be registered, named, and classified into existing concepts explaining their genesis. This study aimed to describe and classify anatomical peculiarities that have not or rarely been reported on before in the literature. This study is based on the observation, analysis, classification, and documentation of three rare phenomena of three different human skull bases and upper cervical vertebrae, which come from the body donor program of the RWTH Aachen. As a result, three osseous phenomena (accessory ossicles, spurs, and bridges) at the CCJ of three different body donors could have been documented, measured, and interpreted. Due to extensive collecting efforts, careful maceration, and accurate observation, it is still possible to add new phenomena to the long list of Proatlas‐manifestations. Further on, it could have been shown again that these manifestations can cause damage to the elements of the CCJ due to altered biomechanic conditions. Finally, we have succeeded in showing that phenomena can exist that can imitate the presence of a Proatlas‐manifestation. Here, a precise differentiation between Proatlas‐based supernumerary structures and the results of fibroostotic processes is necessary.
