Introduction: The stature of an individual, one of the key elements of identification, can be calculated from the length of long bones in the body, of which the femur has the highest correlation with stature. Many a times, forensic anthropologists have to identify unknown dead bodies from fragments of bones that are available. Studies have proven that the total length of a bone can be estimated from fragments using population-specific regression equations. In the present study, the objective was to estimate the total length of the femur (TFL), in an Indian population, from measurements of its distal segment, using regression equations. Material and Methods: One hundred and twenty-one intact adult femurs were studied. The TFL and four variables from its distal segment were measured. Linear regression analysis was performed, and regression equations were derived to calculate the TFL from each of the variables. Results: The mean TFL was 41.9 ± 3.4 cm. All the four parameters of the distal segment showed a significant positive correlation with the total femoral length (P < 0.001), and of these, the width measured between the two epicondyles showed the maximum correlation. Multivariate and univariate regression equations were derived to estimate the TFL from these variables. Discussion and Conclusion: The TFL can be reliably calculated from the measurements of the distal fragments. These measurements can be used by forensic anthropologists for the estimation of the stature of an unknown individual.

Introduction: Pterion is seen in the norma lateralis of the skull and is shaped like the letter H. Pterional approach such as retro-orbital, sellar, sub-frontal, replate areas, anterior circulation, and olfactory meningiomas, tumors involving downstream of the frontal lobe such as the orbital, basilar artery aneurysm is a commonly preferred surgical approach. The present study focused on the typing of the pterion and morphometric measurements between the pterion and surrounding important anatomic spots. Material and Methods: The present study was performed with pterion typing of 107 skull (a total of 214 sides including the right and left sides) within Anatomy Laboratories of Necmettin Erbakan University, Meram Faculty of Medicine, and KTO Karatay University, Medicine Faculty. Distance between the pterion and some important (mid-point of the superior edge of the zygomatic arch, the anterior and posterior edge of the frontozygomatic suture, the tip of the mastoid process, and anterosuperior edge of suprameatal spine and asterion) spots were measured through a digital caliper in millimeter. In addition to the classification made by Murphy, three different classifications were made. The pterion was classified into seven types. Results: The rates of the types were sphenoparietal type by 55.60%, epipteric type by 3.73%, stellate type by 2.33%, frontotemporal type by 0.4%, wormian type by 5.14%, frontoparietal type by 8.87%, and frontoparietal sphenoidtype by 23.83%. Discussion and Conclusion: Morphometric characteristics of the pterion were detected in detail by the present study. Moreover, the knowledge of typing would serve as an important guide for surgical planning and procedures and may contribute to further anthropological studies. This study is aimed at the Central Anatolia population and can be conducted among other populations.

Introduction: To establish normative anthropometric data about the carrying angle, length of the forearm, hip circumference, and body height for young Indian American and Caucasian population and to test statistically the ethnic and gender differences. The objective was also to compare the right and left carrying angle in the ethnic groups. Material and Methods: The present study included 200 students from the American population. Among them, 100 were Caucasians (50 females and 50 males), and 100 were Indian Americans (50 females and 50 males). These participants were aged between 18 and 30 years. Goniometer was used to measure the carrying angle, the hip circumference, body height, and length of forearm were also determined. Results: The present study observed that there was no statistical significance for the carrying angle compared between sides and genders of both the ethnic groups (P > 0.05). The carrying angle was higher (P < 0.05) in Caucasians than in the Indian Americans, both over the right and left upper extremities. This was observed in both the genders. The comparison between genders showed that, carrying angle was higher for females (P < 0.05) than the males in both Caucasians and Indian Americans. Discussion and Conclusion: This investigation contributes the morphological database in Indian Americans and Caucasians for the carrying angle. The morphological findings of this study could be used as reference values for the clinical application and ergonomics. The knowledge about the carrying angle is imperative during the surgical procedures at the elbow joint.

Introduction: Tendons may rarely be ossified. The calcaneal tendon (CT) is the largest in the body. The incidence and mechanism of ossification of CT is not known. Material and Methods: We carried out a morphological, radiological, histological, and immunohistochemical study on the CT of 50 (30 – male and 20 – female) human cadavers. Results: The mean length (cm) of the CT was 27.60 ± 2.30 (right) and 27.51 ± 2.60 (left) in males and 25.43 ± 0.77 on both sides in females. The contribution to the formation of the CT from the two heads of gastrocnemius muscle was greater from medial head in 84%, lateral head in 12%, and equal in 4%. On screening the CT by C-arm radiography, slight opacification at the site of insertion of CT (bilaterally) was noted in an elderly male. Large, bilateral opacification was seen in another elderly male cadaver. Well-defined lamellar bone with osteocytes lying in lacunae and bone marrow amid the tendon collagenous tissue was noted in hematoxylin- and eosin-stained sections. The osteocytes expressed hypoxia-induced factor 1 alpha. Discussion and Conclusion: In this study, we confirmed that the radiological opacification in the CT was ossification that may have been triggered by hypoxia.

Introduction: The aim is to study morphometric analysis of normal and variant anatomy of posterior cerebral artery (PCA) and incidence of fetal PCA (FPCA) in Uttar Pradesh region. The PCA and its cortical branches supply blood to the occipital lobe, inferomedial temporal lobe, and portions of posterior inferior parietal lobe. Fetal-type PCA is a common anatomic variation of PCA that is closely associated with intracranial aneurysm. The present study provides the description of PCA regarding its normal morphology, morphometry, and variations in Uttar Pradesh region. Material and Methods: The study evaluated 100 computed tomography angiograms. Results: Among arteries that displayed normal anatomy, mean diameter of PCA was observed to be 4.29 ± 0.74 mm on the right side and 2.47 ± 0.74 mm on the left side. Mean diameter in males and in females was found to be 2.48 ± 0.73 mm and 2.47 ± 0.74 mm, respectively. In 56.5% of cases, the diameters of P1 segment of PCAs ranged from 2.1 to 3 mm whereas >3 mm diameter was observed in 18.5% cases. Nineteen percent cases showed 1.1–2 mm. In 6% cases, hypoplasia (≤1 mm) of PCA was observed. FPCA was observed in 26% cases. Unilateral observed in 17% cases and bilateral in 9% cases and the difference was statistically significant (P < 0.000). Discussion and Conclusion: Anomalies of PCA may assume considerable significance in surgeries of head and neck, which require ligation of internal carotid and common carotid artery. Awareness of these anatomical variations described shall prove to be useful for any cerebrovascular procedures.

Introduction: Iron deficiency anemia is the most prevalent nutritional deficiency disorder in pregnant women. During pregnancy, nutrients, including iron, are transferred from the mother to the fetus through the placenta, in which the placental transport protein Ferroportin1 (FPN1) plays a crucial role. It has been frequently observed that developing fetus is immune to anemia despite the presence of anemia in the mother, the mechanisms underlying which have not been identified. We, therefore, planned the present study to explore the effect of maternal iron deficiency anemia on the expression of FPN1 in the placenta. Material and Methods: Two hundred pregnant women recruited were divided into anemic and nonanemic groups based on their predelivery hemoglobin levels (<11 g/dl and ≥11 g/dl, respectively). After delivery, placental expression of FPN1 was studied by immunohistochemistry and mRNA analysis, and neonatal anthropometry was performed. Results: Of the 200 women, 59% were anemic. FPN1 protein immunohistochemical staining in placenta showed a statistically significant increase with increasing severity of anemia. Similarly, placental mRNA expression levels of the FPN1 gene were observed to be higher in anemic mothers when compared with nonanemic mothers. Discussion and Conclusion: Thus, our study for the first time shows that maternal iron deficiency increases placental FPN1 protein and mRNA expression, thereby probably facilitating increased transport of iron from the mother to the fetus.

Introduction: The purpose of the present study was to investigate the vertebral levels of the aortic bifurcation (AB) in patients with and without the abdominal aorta (AA) deviation and to measure the distances between the AB and the right-left common iliac bifurcations (CIBs) which are crucial anatomical information, especially for anterior lumbar interbody fusion surgery. Additionally, we made comparisons levels of the AB according to sex and examined whether the results were statistically significant, which we could not find other studies comparing gender in literature. Material and Methods: The images of 721 patients, undergoing angiography with multidetector computed tomography between January 2016 and October 2019, were reviewed retrospectively. The AB levels of the patients with and without the AA deviation were classified and evaluated separately. It was measured the distances between the level of the AB and the right and left CIBs with the 3-dimensional ruler technique in only 207 of 721 patients. Results: It was detected seven different vertebral levels of the AB among patients (116 patients) with the AA deviation, in which is the highest L4-upper (27.59%), and 11 different vertebral levels of the AB among patients (605 patients) without the AA deviation, in which is the highest L4-upper (22.48%). When comparing cases with and without AA deviation, a statistically significant difference was found between the sexes (P < 0.05). Discussion and Conclusion: The presented study demonstrates that there is a significant relationship between the genders at some levels. The preoperative information of the morphological variations of the AB may be very useful for laparoscopic, invasive procedures, and spinal surgery procedures. At the same time, these variation information reveals new information for anatomy.

Biceps brachii muscle is basically a powerful supinator. Although there is ample literature on variant origin of biceps brachii, variant insertion pattern was minimally reported. Here, we report a case, in which apart from usual insertion of biceps brachii, three distal accessory aponeurotic slips were found on the right arm of 55-year-old embalmed male cadaver. Two slips were arising from the lateral most part of bicipital aponeurosis traversing across the cubital fossa superficial to the brachial artery and median nerve and get attached to deep fascia covering the brachioradialis and pronator teres. Third accessory aponeurotic slip arises from the lateral side of biceps brachii muscle belly, traversing superficial to the musculocutaneous nerve and get attached to deep fascia covering the lateral border of brachioradialis and extensor carpi radialis longus. These extra slips may affect the kinematics of biceps brachii muscle and adds to the differential diagnosis of variety of clinical symptoms of neurovascular syndrome.

Two slips were arising from the lateral most part of bicipital aponeurosis traversing across the cubital fossa superficial to the brachial artery and median nerve and get attached to deep fascia covering the brachioradialis and pronator teres. Third accessory aponeurotic slip arises from the lateral side of biceps brachii muscle belly, traversing superficial to the musculocutaneous nerve and get attached to deep fascia covering the lateral border of brachioradialis and extensor carpi radialis longus. These extra slips may affect the kinematics of biceps brachii muscle and adds to the differential diagnosis of variety of clinical symptoms of neurovascular syndrome.","PeriodicalId":50010,"journal":{"name":"Journal of the Anatomical Society of India","volume":"71 1","pages":"74 - 75"},"PeriodicalIF":0.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41882224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction: The aim of this study was to evaluate the changes of the pharyngeal airway obtained using mono-and bimaxillary orthognathic surgery in patients with skeletal malocclusion. Material and Methods: The analysis was conducted on cone-beam computed tomography images taken preoperatively and postoperatively of patients undergoing mono-or bimaxillary orthognathic surgery. The pharyngeal airway was divided into four airway volume segments and measured by planimetry. Results: The bimaxillary surgery group showed an increase in nasopharynx and velopharynx volumes and a decrease in glossopharynx and hypopharynx volumes (P < 0.05). The mandibular setback surgery group showed decreases in glossopharynx, hypopharynx, oropharynx, and pharynx volumes (P < 0.05). The mandibular advancement surgery group showed increases in glossopharynx, hypopharynx, oropharynx, and pharynx volumes (P < 0.05). The maxillary advancement surgery group showed increases in nasopharynx, velopharynx, and pharynx volumes (P < 0.05). Discussion and Conclusion: Mandibular setback surgery had a narrowing effect on the pharyngeal airway volume. Maxillary advancement surgery compensated for the constrictive effect of mandibular setback surgery on both the oropharynx and pharynx volumes. Although maxillary and mandibular advancement surgery affected different sites, these were the operations that contributed most to the increase in pharyngeal volume.
