Abstract Aim To measure the size of tentorial notch in Indian population, compare it with the western population from the literature available, and analyze the relation between size of tentorial notch and the outcome in patients with head injury. Materials and Methods The study was done using 10 cadavers and 15 autopsy specimens. In all the specimens, tentorial incisura was measured using vernier caliper after opening the skull and cutting the midbrain at the level of tentorial edge carefully without damaging the tentorium. All measurements were done in millimeters. Results Mean values, age-dependent mean values, and percentile values were calculated for various parameters in the tentorial incisura. Majority of the tentorial incisura are of typical type. Cases of tentorial incisura are significantly smaller in the age group of 20 to 25 years. Rate of deterioration of Glasgow coma scale (GCS) is rapid when the tentorial incisura is large. Conclusion There were no significant variations in measurements of tentorial incisura in Indian population compared with the western population. Rate of deterioration of GCS is higher in patients who had large tentorial incisura compared with other groups, which is statistically significance. However, this is to be confirmed by further study using large groups of patients to be used for clinical applications.

<p class="abstract"><strong>Background:</strong> The larynx besides being used in respiration, performs the function of production of voice. A thorough knowledge of relevant surgical anatomy is a must for any surgeon before performing laryngeal framework surgery (LFS). Most of the relevant anatomic details for LFS are based on Western population and the studies based on Indian population are extremely scarce. We propose to undertake this study in order to understand the relevant anatomy of the thyroid cartilage in adult Indian population and to compare these dimensions with those studied in the western population as available in literature.</p><p class="abstract"><strong>Methods:</strong> Fifty-two samples of adult thyroid cartilage (35 males and 17 females) taken from cadavers were analysed.

Abstract Background and Aim of the study: Vagus the wanderer is the tenth cranial nerve with long extra cranial course. Below the bifurcation of trachea, the right and left vagi form plexus around the oesophagus before they enter the abdomen as anterior and posterior vagal trunks. There are variations in the contribution by the right and left vagi for the formation of oesophageal plexus and according to Chamberlin and Winship there are three different patterns in the formation of peri oesophageal plexus. The present study was aimed to study the formation of perioesophageal plexus, incidence of different patterns of peri oesophageal plexus in south Iudian population and the number of vagal trunks formed from the oesophageal plexus in the lower end of the oesophagus. Materials and Methods : The formation of perioesophageal plexus Gulae was studied in forty four autopsy specimens of oesophagus and stomach and six foetal specimens at Institute of Anatomy, Madras Medical College, Chennai. Results : The formation of perioesophageal plexus and the number of fibres from the right and left vagus nerves which contribute to the plexus formation were studied. There were significant differences in the formation of plexus Gulae. There were variations in the pattern of perioesophageal plexus and the number of vagal trunks arising from the plexus. The results of the present study in South Indian population were compared with the results in the Western population. Conclusions : Awareness regarding the presence of plexus Gulae and number of vagal trunks related to lower end of oesophagus has considerable importance in the surgical repair of hiatus hernia and while treating atrial fibrillation.

Abstract OBJECTIVE: The tentorial notch can be contained within a transversal line made in front of the cerebral peduncles and another line through the posterior border of the quadrigeminal plate into the anterior, middle and posterior parts. Different approaches to the tentorial incisura have been established. The subtemporal approach represents one of those options. Since morphometrical analyses of this approach in this region have not yet been performed, the aim of the present study was to measure the surgical corridor along these borders. METHODS: Fifty-three magnetization prepared rapid acquisition gradient echo-sequences of individual brains without pathological lesions were analyzed. For this study, an axial section along the pontomesencephalic sulcus and two coronal sections along the above-described borders were measured using a program specially written by one of the coauthors to obtain various parameters. A triangle circumscribing the surgical corridor was delimited by exactly defined anatomic landmarks for the coronal section, and the depths of the temporal lobe at the incisural borders were measured for the axial section. RESULTS: Various data are given concerning the surgical corridor of a subtemporal approach to the tentorial incisura. The different shapes of this corridor to the incisural region were recorded. According to our measurements, four different types of the temporal lobe could be differentiated. CONCLUSION: Knowledge of these distances and various contours of the path is crucial to avoid brain damage during retraction or manipulation. The curvature of the floor of the middle cranial fossa is highly variable and thus determines the surgical path chosen.

Background: Craniosynostosis is one the major genetic disorder in children and it occurs in 1 per 2,200 live births. It may be define as abnormal premature fusion of the cranial sutures bones in children. Several causes have been reported that may have a possible role in the development of the disorder. Fibrinogen growth Factor 1(FGFR1) & fibroblast growth factor receptor 2 (FGFR2) show a vital role in developing the craniosynostosis in western population?s children but from India no report is available. The aim of this study was to investigate the association between mutation of FGFR1 and FGFR2 (IIIa and IIIb) genes with syndromic as well as non-syndromic craniosynostosis in Indian population. Methods: Retrospective analysis of our records from January 2008 to December 2012 was done. A total of Sixty three children (along with their parents) with craniosynostosis and Fifty one children with No-craniosynostosis (healthy school going children) attending the Monday out Patient Door (OPD) facility of the department of Paediatric Surgery, All India Institute of Medical Sciences (AIIMSs), Delhi, India were considered for the study. A restriction fragment length polymorphism (RFLP) polymerase chain reaction (PCR) was carried out for genotyping Fibrinogen growth Factor 1 (FGFR1) & fibroblast growth factor receptor 2 (FGFR2) mutations in all the participants. Results: There were 33 (80.4%) nonsyndromic cases of craniosynostosis while 8 (19.5%) were syndromic. Out of these 8 syndromic cases, 4 were Apert syndrome, 3 were Crouzon syndrome and 1 Pfeiffer syndrome. Phenotypically the most common nonsyndromic craniosynostosis was scaphocephaly (19, 57.7%) followed by plagiocephaly in (14, 42.3%). FGFR1 mutation (Pro252Arg) was seen in 1 (2.4%) case of nonsyndromic craniosynostosis while no association was noted either with FGFR1 or with FGFR2 (IIIa & IIIc) mutation in syndromic cases. None of the control group showed any mutation. Conclusion: Our study provides the strongest evidence that association of mutation of FGFR1, FGFR2 (IIIa & IIIb) with syndromic as well as nonsyndromic craniosynostosis does not exist in Indian population as seen in western population.

ABSTRACTThe implants for fixation of proximal femur fractures and joint replacements have been designed taking into consideration of the anthropometry of the western population which vary from other ethnic groups. The present study aimed to study the morphology of the upper end of femur in relation to its various diameters and angles and compare the external and internal geometry of proximal femur as obtained from radiographs, with actual measurements on cadaveric specimens in Indian population. Seventy five pairs (150 bones) of cadaveric femora were studied morphologically and radiologically using standardized techniques to obtain various anthropometrics measurements. These values were compared with those reported in the literature for Hong Kong Chinese, Caucasian, Chinese and Western populations. Data were found to be quite different from them. It is proposed that implants designed for Western populations should be used judiciously and future implants be designed to match the morphology of the Indian bones.

Introduction: There is increasing emphasis on the sagittal spino-pelvic alignment and its interpretation is of critical importance in the management of spinal disorders. A cross-sectional study of several spino-pelvic radiographic parameters was conducted to determine the physiological values of these parameters, to calculate the variations of these parameters according to epidemiological data, and to study the relationships among these parameters. Material and method: Fifty normal healthy volunteers (29 males and 21 females) with no history of back pain were selected and were subjected to standing sagittal spino-pelvic radiographs. All the measurements of various radiographic parameters were performed with use of a software program. A statistical analysis was done to study the relationships among them. Results: The mean values of pelvic incidence (PI) and lumbar Lordosis Angle (LLA) were 48.52 ± 8.99 and 58.78 ± 9.51, respectively. There was statistical difference between male and female parameters in LLA, lumbo-sacral angle (LSA), sacral horizontal angle (SHA), sacral inclination angle (SIA), sacropelvic angle (PRS1), pelvisacral angle (PSA), and PI. A majority of parameters had higher values for female subjects when compared to male subjects. PI was positively correlated with LLA, pelvic angle (PA), pelvic overhang (PO), pelvic tilt (PT), sacrofemoral distance (SFD), SHA, and sacropelvic translation (SPT), which were highly significant, whereas LLA was positively correlated with SHA and SIA only. PI and LLA were both negatively correlated with PSA, pelvic thickness (PTH), and PRS1. Conclusions: This study presents the various spino-pelvic radiographic parameter values of a sample of the normal asymptomatic Indian population. There was significant difference in radiographic parameters between males and females in about half of the parameters studied in the sample. The values obtained are comparable with the values presented as normal in the literature. A comparison of the study results with data published about other populations revealed no differences in any of the pelvic parameters between the Indian, Brazilian, and Korean populations.

The distal femurs of 100 subjects (50 men, 50 women) from the Malay population aged between 19 and 38 years were scanned to measure the anterior-posterior (AP) and medial-lateral (ML) width. The mean AP values were 64.02 ± 3.38 mm and 57.33 ± 3.26 mm for men and women, respectively, and the mean ML values were 74.91 ± 3.52 mm and 64.53 ± 3.07 mm. We compared our data to that published previously for the Chinese and Indian populations. It was found that the Malay population had smaller distal femur than that of the Chinese but was larger than that of the Indian population (P< 0.05). In conclusion, although it is well established that Asians have a smaller distal femur size than that of the Western population, the variations in different Asian ethnicities may need to be considered when designing the appropriate knee implant.
