    Does race have a role in the effect of fingerprint on gender?
    (2021) Avnioğlu, Seda; Dikici, Rumeysa; Yılmaz, Halil
    Aim: Fingerprint is one of the personal and reliable physical features. The fingerprint has an important role in forensics, and it is used in the detection of criminals and identity checks. Studies on different races have been conducted, but no interracial comparison has been found in the literature. In this study, we have investigated the effect of race on finger ridge using the same method on 5 different races. Methods: In our study, the right thumb prints of 355 (148 female, 207 male) students aged 17-25 years in our school were taken with an ink pad (stamp) and recorded along with their ages, sexes, and races. Data were analysed by sex and race. Results: In the comparison by sex, the finger ridge counts of male (11.94±2.08) and female (12.76±2.02) participants were found to be statistically significantly different (p<0.001). Participants were classified as Turkish, Arab, Russian, Turkmen, and African. The difference in finger ridge counts between Turkish-Africans was found to be statistically significant in the comparison by races (p<0.05). Conclusion: Comparison of finger ridge counts by sex has been studied on many races, but each study has been conducted with a different method. In our study, we aimed to contribute to the literature by examining how the finger ridge counts of men and women differ in 5 different races by using the same method. Although the data we obtained are compatible with the literature for the Turkish race, there are differences for other races.

    Investigation of the Relationship Between foot Deformities and Radiographic Measurements of the Talus and Calcaneus
    (2022) Candan, Büşra; Torun, Ebru; Dikici, Rumeysa
    The weight of the body is transmitted to the foot through the subtalar joint and talus. Considering the important location of the talus and calcaneus, the morphological structures of these bones may affect the biomechanics of the subtalar joint. At the same time, the morphological structure of these bones is important in some common foot deformities. We aimed to investigate whether the various measurements of the talus and calcaneus are associated with different foot deformities in this study. In this study, radiography images of 158 (72 male and 86 female) patients within the mean age of 44 years were retrospectively examined. Eleven different measurements of the talus and calcaneus were obtained from the lateral and antero-posterior radiographs of the patients. A total of 158 patient's routine clinic radiographs were retrospectively assessed, which have calcaneal spur (n=63), hallux valgus (n=32) and control group (n=63). We determined that the body height of the calcaneus, maximum width of the head of the talus, minimum anterior width of the calcaneus were significantly different between calcaneal spur group and control group. Maximum length fibular malleolar facet of the talus was significantly different between age groups. And we determined that the calcaneal index was significantly different between hallux valgus group and control groups. Also all measurements were significantly different between males and females. As a result, some measurements that significantly determine the morphology of the talus and calcaneus were found to be significant between deformity groups and control groups. We think that our study will contribute to the literature as it is the first study in which the measurements obtained from the radiographic images of the talus and calcaneus are associated with foot deformities.

    The Prevalence of Accessory Ossicles, Sesamoid Bones, and Biphalangism of the Foot and Ankle: A Radiographic Study Open Access
    (2022) Candan, Büşra; Torun, Ebru; Dikici, Rumeysa
    Abstract Background: Accessory ossicles, sesamoid bones, and biphalangism of toes are the most common developmental variations of the foot. These bones may be associated with painful syndromes; however, their clinical importance is not well understood because the reported prevalence varies widely. Therefore, we aimed to investigate these variants in Turkish subjects. Methods: A total of 1651 foot radiographs were retrospectively assessed. Radiographs of feet were examined regarding the prevalence, sex, and bilaterality of accessory ossicles, sesamoid bones, and biphalangism in Turkish subjects. Results: Accessory ossicles (26.1%) and sesamoid bones (8%) were detected. The most common accessory ossicles were os trigonum (9.8%), accessory navicular bone (7.9%), and os peroneum (5.8%). Also, we detected os supratalare (0.48%), os calcanei secundarium (0.42%) os subfibulare (0.42%), os supranaviculare (0.36%), os vesalianum (0.30%), os subtibiale (0.24%), os intermetatarseum (0.12%), and os subcalcis (0.12%). We observed bipartite hallux sesamoid in 1.8% and interphalangeal sesamoid bone of the hallux in 0.7% of radiographs. Incidences of metatarsophalangeal sesamoid bones were found as 0.6%, 0.06%, 0.6%, and 5.8% in the second, third, fourth, and fifth digit, respectively. We observed biphalangeal toe in 0.5%, 1.7%, 3.5%, and 37.6% in the second, third, fourth, and fifth toe, respectively. Conclusion: This study is the first detailed report on the incidence of the most common variants of the foot and ankle in a wide-ranging patients’ series in Turkish subjects. Our study’s findings will contribute to reducing misdiagnosis. Clinical Relevance: The results of this study may provide anatomical data that could help clinicians in the diagnosis and management of disorders that present with pain and discomfort in the feet. Knowledge of these variants is important to prevent misinterpreting them as fractures.
