Purpose The aim of this study is to evaluate of morphometry of the lateral meniscus (LM) and determine incidence of the LM shapes. Methods This study was performed on fetal cadaver collection of Anatomy Department of Necmettin Erbakan University. Fifty human fetal cadavers (25 female, 25 male human fetal cadavers) were used in this study. Microdissection was performed. Morphometric measurements were performed. LM were classiied into four types and ive subtypes. ResultsIn this study, it was identiied that all parameters which were measured were found to be increased with gestational ages. Four morphological types and ive morphological subtypes were determined. It was found that 12% of the LM were crescent-shaped, 66% of the LM were C-shaped, 14% of the LM were incomplete-disc-shaped, 2% of the LM were discshaped, 6% of the LM were variant C-shaped. Conclusions A few studies on fetal meniscal anatomy and its development were performed. Each new study is important for having detailed anatomy and development of the fetal menisci which will have both clinical and anatomical impacts during childhood and adulthood for orthopedic surgeons and anatomists, respectively. The most important results of this study were the detailed objective analysis of the macroscopic fetal growth of LM. It was signiicantly observed that four morphological types and ive morphological subtypes of LM. The results of the present study related with both the observation of morphological development of the fetal meniscal anatomy, and its morphological variants, are important in terms of improving our knowledge, and clinical approach on the description, and the management of the symptomatic lateral discoid meniscus tears in children, adolescents, and adults. The clinical relevance of this study was that this classiication of fetal menisci could ameliorate our current understanding of the morphology of lateral meniscus in adult, further.

D.Morphometric analysis of suprarenal glands (adrenal glands) with multislice computerized tomography. Int. J. Morphol., 35(1):120-127, 2017. SUMMARY:The aim of our study are to determine the shape, vertebrae level, height, volume, corpus medial and lateral branch thicknesses of AG and the distance from some neighboring structures on multidetector computed tomography (MDCT) images and also to determine the relationship between these data and gender, age, height, weight and body mass index (BMI). The study was conducted on a total of 420 MDCT images consisted of 220 male (mean age 63.44±8.00, 50-81 years), 200 female (mean age 61.23±7.95, 50-84 years) healthy individuals. Vertebrae level of AG (VLAG), height of AG (HAG), adrenal gland volume (VAG), corpus thickness of AG (CTAG), medial section thickness of AG (MTAG) and lateral section thickness of AG (LTAG) were investigated. In our study, RAG were observed on T12 vertebrae level in 38.19 % of males and 42.5 % of females and LAG were also observed at that level in 39.55 % of the male and 51 % of the female individuals. RAG were observed in all males and 98.5 % of the females and LAG were observed 88.63 % of the males and 94 % of the females "Y" shaped. VAG were observed lower in males compared to females in age groups and VAG was observed increasing with age in males; decreased in 60-69 age group of females and increased again in 70 and plus age group. The aim of this study is to determine normal ranges of AG sizes and the relationship of each one with sex, age, height, weight and BMI.
SUMMARY: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.
Background/aim: The aim of the present study was to determine the course and possible variations of the sural nerve with all anatomical details in human fetal cadavers. Materials and methods: This study was performed on 60 fetal cadavers. Formation type and level of the sural nerve was detected. Results: According to trimesters, it was determined that the mean transverse and vertical distance between the lowest point of the LM and the SN varied between 1.1-2.9 mm and 1.54-3.58 mm, respectively. Type 2 was the most common seen type of sural nerve (35,83%). It was determined that sural nerve was mostly formed at the middle third of the leg (42,5%). Conclusion: Sural nerve graft with the knowledge of the anatomical details may be used for peripheral nerve reconstruction is required in congenital lesions, such as facial paralysis, obstetric brachial paralysis, and post-traumatic lesions in infants and children.
SALBACAK, A.; AKIN, D.; KABAKCI, A. D. A.; YILMAZ, M. T.; CICEKCIBASI, A. E. & OZBEK, O.Morphometric analysis of the inferior vena cava related to the lumbar vertebra and the aortic bifurcation on multidetector computed tomography (MDCT). Int. J. Morphol., 34(2):620-627, 2016. SUMMARY:Vascular structures are in greater danger during lumbar surgery. The purpose of this study is to describe the morphology of the inferior vena cava (IVC) related to the lumbar vertebra and aortic bifurcation (AB) and assessing the role of demographic values in these relations to decrease the risk of complications in the surgical interventions. The study was performed on Multidetector Computed Tomography (MDCT) images of 100 male and 100 female cases with an age range from 50 to 84 years. The morphometric values of the IVC obtained from the coronal, sagittal and the axial reformatted images were measured and compared with the demographic values. The distance from the IVC to the 1 st lumbar vertebra (L1) and 2 nd lumbar vertebra (L2) were measured as (26.5 mm and 18.1 mm) in males and (21.1 mm and 14.2 mm) in females with a high level of significance between genders; the distance from the IVC to the iliocaval confluence (IC), 3 rd lumbar vertebra (L3) and 4 rd lumbar vertebra (L4) were measured as (6.5 mm, 10.5 mm and 6.9 mm) in males and (4.9 mm, 9.1 mm and 5.5 mm) in females with significance between genders. The level of the IC was detected 46 % of males, 39 % of females at the level of lower third of L4. The vertical distance between the IC and the AB was measured and negative correlation between genders based on age was detected. Demographic values are important to consider the relationship of the IVC, the lumbar vertebra and the AB. The IVC was located further from the lumbar vertebra in males compared to females. Age increase played role in the approaching of the AB and the IC to each other in both gender and the IC to the promontory level in males.
Background: The aim of this study was to compare the morphological differences in the mandible between patients with six age groups and to detect the correlation between these parameters on panoramic radiography (PR) and cone-beam computed tomography (CBCT). Materials and methods: A total of 121 subjects (50 males and 71 females) were included in the study and were divided into six age groups (10-19, 20-29, 30-39, 40-49, 50-59, and 60-69) on the basis of the chronological age. CBCT and PR methods were used to record the mandibular measurements for the same 121 patients. Differences between male and female mandibular morphometric measurements, between right and left side measurements, and differences in age subgroups compared by using independent samples t-test, paired samples t-test, and one-way ANOVA test, respectively. P < 0.05 value was considered statistically significant for all analysis. Results: Males mostly have higher mandibular measurement values. There were statistically significant differences between CBCT and PR measurements (p < 0.05). PR mostly showed higher values than CBCT measurements. Conclusions: Based on the fact that PRs showing significant differences from CBCT in the morphometric measurements made on mandible, it is recommended that forensic doctors and anthropologists consider this information in their age and gender prediction studies.
Aim: The recognition of the scapula anatomy and visible variations is important in surgical treatments and arthroscopic procedures in case of any diseases of the shoulder. The morphological and morphometric characteristics of the scapular notch on the superor margin are very important. Because, compression of the suprascapular nerve extending inside the scapular notch causes entrapment neuropathy. Therefore, the present study was planned in order to contribute to us as well as practitioners about morphometric and morphological characteristics of the superior margin of the scapula. Materials and Methods: Morphometric measurements (SL: scapule length; SW: scapule width; SI: scapula index; STD: superior transverse diameter of the scapular notch; MTD: medial transverse diameter of the scapular notch; VD: vertical diameter) were performed on 90 (50 left; 40 right) scapulae of Turkish population without uknown age and gender. Furthermore, the superior scapular margin and the scapular notch were categorized through observational classification as well as measurement. Results: The mean scapular width was detected 98.87±7.71 mm on the right and 94.38±13.01 mm on the left. The scapula index was measured 67.51±4.40 mm on the right and 63.80±8.29 mm on the left. The SL, STD and VT was larger on the left; the SW, SI and MTD were larger on the right. The difference between right and left for the SW and SI measurements was statistically significant (pMTD (%48.9). The most common superior margin type was moderately oblique (41.1%). Conclusion: We believe that the data obtained would be helpful for orthopedic surgeons in intramedullary nailing and radiologists in the differential diagnosis of some osteolytic lesions in that region. Furthermore, scapula measurements would help to identify the gender and race in forensic medicine and antropology.
