    Anatomical structure and topographic anatomy of sciatic nerve in human fetuses
    (Wolters Kluwer Medknow Publications, 2016) Kabakci, A. D. Aydin; Buyukmumcu, M.; Yilmaz, M. T.; Cicekcibasi, A. E.; Akin, D.
    Introduction: Sciatic nerve is the longest and thickest nerve of the human body which divides into two branches in popliteal fossa. Variations of sciatic nerve can be observed during the course of the nerve. These anatomical variations contribute to some clinical manifestations such as piriformis syndrome, sciatalgia. Methods: This study was conducted on 60 aborted fetuses aged between 9 and 40 gestational weeks and with no gross anomalies. Morphometrical measurements related to the nerve and the neighboring structures were performed and also incidence of anatomical variations was determined. Results: All parametric data were seen increased with gestational age (p < 0.05). Also, no statistical differences between the parameters from right and left were found (p > 0.05). The sciatic nerve division was observed in 99 (82.5%) lower extremities in the popliteal fossa, 19 (15.83%) at a level above the popliteal fossa, and in 2 lower extremities (1.67%), high division was observed. Also, the status of sciatic nerve was assessed in regard to piriformis muscle. In 118 of the lower extremities (98.3%), sciatic nerve was observed leaving from underneath the piriformis muscle as one piece and the remaining 2 (1.67%) were observed as giving division at higher levels. In one of these lower extremities of the right side, tibial nerve branch was observed following a path under piriformis muscle and common peroneal nerve was observed passing through the piriformis nerve. Discussion: We believe that our study will provide data regarding the development of sciatic nerve in fetal period and that data will contribute to related clinical studies and applications.

    An Osteometric Study on Humerus
    (Soc Chilena Anatomia, 2017) Aydin Kabakci, A. D.; Buyukmumcu, M.; Yilmaz, M. T.; Cicekcibasi, A. E.; Akin, D.; Cihan, E.
    Humerus is the longest and thickest bone of the upper limb. As a long bone, it has two epiphysis and diaphysis. In this study, we aimed to conduct morphometric measurements belonging to human humerus. This study was conducted on 60 humerus (28 right, 32 left) in collections of Necmettin Erbakan University Meram Medicine Faculty Anatomy Laboratory. Digital calipers, osteometric board and precision scales for humerus bone measurements were used. Measurements were classified as measurements of diaphysis and proximal and distal epiphysis of humerus. Each bone weight was determined. Also nutrient foramen number and localization was determined. In this study, it was determined that mean right humerus length 30.41 +/- 1.73 mm, mean left humerus length 30.04 +/- 2.39 mm. It was identified that mean right humerus weight was 115.05 +/- 28.06 g, mean left humerus weigh twas 111.63 +/- 33.34 g. In 9 humerus (15 %), supratrochlear foramen has been observed. 6 of these were oval and 3 of them were round. Nutrient foramen has not been observed in two humerus (3.3 %). Also, medium and weak correlation was identified between many parameters. We believe that the obtained data from this study may be qualities of reference for sex determination from humerus.
