ABSTRACT

It was aimed in this study that the morphometric development of the hand in human fetuses throughout the fetal period be radiologically investigated and the clinical importance of this period be evaluated. A total of 50 fetuses with no external pathology or anomaly, and the ages of which varied between 20-40 gestational weeks were incorporated into the study. The fetuses were separated into groups according to gestational weeks, trimesters and months. After the general external measurements of the fetuses were performed, mammography and hand radiographies of the fetuses were shot in the way that their hands would be in a pronational position. Afterwards, the morphometric measurements of the hands were performed with the help of a digital caliper through the hand radiographies that were shot. The averages and standard deviations of the measured parameters were determined according to gestational weeks, trimesters and months. There was a significant correlation between the measured parameters and the gestational age (p<0.001). Additionally, it was observed that there was some difference among the groups in the comparison of the measured parameters involving trimesters and months (p<0.05). We are of the opinion that in evaluating the clinical studies regarding the morphometric development of the hand throughout the fetal period and in determining the pathologies and variations related to the fetal hand development, the data obtained in our study will be of use to the clinicians engaged in gynecology, and forensic medicine as well as those involved in this field.


Se investigó radiológicamente el desarrollo morfométrico de la mano en fetos humanos a lo largo del período fetal y se evaluó la importancia clínica de este período. La muestra consistió en 50 fetos de 20 a 40 semanas de gestación, sin patología externa o anomalía. Los fetos se dividieron en grupos según las semanas, trimestres y meses de gestación. Después de las mediciones externas generales de los fetos se realizaron mamografías y radiografías de mano de los fetos en posición de pronación. Posteriormente, las mediciones morfométricas de las manos se realizaron en las radiografías con la ayuda de un calibre digital. Hubo una correlación significativa entre los parámetros medidos y la edad gestacional (p <0,001). Adicionalmente, se observó que hubo una diferencia entre los grupos en la comparación de los parámetros medidos según los trimestres y meses (p <0,05). Consideramos que al evaluar los estudios clínicos sobre el desarrollo morfométrico de la mano a lo largo del período fetal y la determinación de patologías y variaciones relacionadas con el desarrollo de ésta, serán de utilidad para los clínicos intervinientes en las áreas de ginecología y medicina forense.

ABSTRACT

It was aimed that the morphometric development of the hyoid bone throughout the fetal period be anatomically researched and its clinical importance be evaluated. A total of 90 human fetuses (44 male, 46 female) whose ages varied between 18 and 40 gestational weeks and without an external pathology or anomaly were involved in the study. The fetuses were divided into groups according to gestational weeks and trimesters. In the wake of making the general external measurements of fetuses, the neck dissection was performed. Following the localization of the hyoid bone, the morphometric parameters pertaining to the hyoid bone were measured. The averages of the measured parameters according to the gestational weeks, trimesters and months, and their standard deviations were determined. There was a significant correlation between the measured parameters and the gestational age (p < 0.001). Between the genders, there was no difference among the other parameters, except for those regarding the distance between the hyoid bone and columna vertebralis, the hyoid bone corpus length, the hyoid bone right cornu majus initial width, the hyoid bone left cornu majus initial width, and the upper distance between the hyoid bone cornu majus (es) (p > 0.001). We are of the opinion that the data obtained during our study will be of use to forensic physicians and the involved clinicians in the evaluation of the development of the hyoid bone area during the fetal period, and in clinical studies and practices.
