The fibularis brevis tendon and plantar aponeurosis lateral band are important in the pathogenesis of proximal fifth metatarsal fractures. This study aimed to evaluate the insertion morphology of the fibularis brevis tendon and plantar aponeurosis lateral band on the fifth metatarsal base using Korean cadavers. As the research object, we used 96 feet 48 Korean cadavers (33 male, 15 female), with an average age at death of 78.7±12.4 years. Morphological classification of the fibularis brevis tendon insertion was performed using the method of Imre et al. For morphological measurement, the length of the area where the fibularis brevis tendon and plantar aponeurosis lateral band were inserted was measured. The insertion of the fibularis brevis tendon was classified into three types: type 1 with one tendon in 51 feet (53.1%), type 2 with two tendons in 39 feet (40.6%), and type 3 with three tendons in 6 feet (6.2%). The length at the point of insertion with the fibularis brevis tendon was 14±4.3 mm, and the length at the point of insertion with the plantar aponeurosis lateral band was 14.1± 4.6 mm. In conclusion, this study suggests that the morphological characteristics of the fibularis brevis tendon and plantar aponeurosis lateral band could provide basic anatomical data for a new classification of avulsion fractures.

The human skull has a very complex and diverse structure, and morphological characteristics are distinct by race. The purpose of this study is to classify the skull shape of the Korean population by applying two classification methods using post-mortem computed tomography (PMCT) images, and to obtain anatomical data by comparing characteristics by gender and age group. 146 PMCT cross-sectional images (72 males, 74 females) provided by the National Forensic Service were analyzed, and the average age was 54.7±18.8 years. The maximum cranial length was divided by the maximum cranial width and multiplied by 100 to calculate the cranial index (CI). Petrous ridge-midline angle (PMA) was measured as the angle between the petrous ridge and the midline. In CI cranial morphology classification, brachycranic was found in 129 (88.4%) and mesocranic 17 (11.6%) cases, and brachycranic showed the highest frequency. There was no significant difference in the frequency of skull morphology by gender and age group. In the skull morphology classification of PMA, brachycranic was identified in 86 (58.9%), mesocranic in 57 (39.0%), and dolicocranic in 3 (2.1%), and brachycranic showed the highest frequency. In the frequency analysis by gender, male brachycranic showed higher frequency than female (p=0.010). In the frequency analysis for age groups, the frequency of brachycranic in the middle and old age groups was higher than in the young age group (p=0.047). In conclusion, Brachycranic showed the highest frequency in both CI and PMA cranial morphology classification, which is considered to be useful basic data that can be used clinically and forensic anthropology.

It goes without saying that the influence of Andreas Vesalius and his book, De Humani Corporis Fabrica Libri Septum (Fabrica) on the development of modern anatomy is absolutely enormous. The book 1 of Fabrica composing of seven books deals with the osteology, and the famous three figures of whole body bones and index of the terminologies are at the last part of the book. The diverse languages in the index are first noticeable, which are not only Latin, the language of Fabrica, but old Greek, Hebrew, Arabic. The old Greek and Hebrew words are expressed by their own letters, but the Arabic words are indirectly expressed by Latin letters for their original phonations. While same terminologies are sometimes used for two different structures, several different terminologies are commonly used for one same structure, which implies the chaotic situation in anatomical terminology at those times. The terminologies in the index have been tabulated in this study, and the historical development of terminology of bones was discussed with reflecting the efforts of the precedent anatomists had poured into unification and settlement of anatomical terminologies.
