Aim: The commonly used examination procedures of the upper cervical spine depend upon the symmetry for comparison and interpretation of joint functions. If symmetry is not normal, then these assessments may mislead the examiner and thus allows implementation of incorrect treatment plans. Objectives: Of this study are to explore the possibility that asymmetry is more common than symmetry and, if it is true, to find out the magnitude and statistical significance of intra-atlas asymmetry and to discuss the effects of asymmetry on the biomechanics and the methods used to evaluate these joints. Materials and methods: This study was carried out on 30 adult human atlas vertebrae of cadavers of Indian origin. The different intra-atlas distances were measured for both sides of the atlas by digital vernier calliper. Results: All the parameters studied showed statistically significant differences between the right and left side. The anteroposterior diameter of the foramen transversarium, the transverse diameter of the foramen transversarium, the distance from the midline to medial edge of the Vertebral Artery Groove (inner as well as outer cortex) and the length of the superior articular facets were more on the right side as compared to the left side. The breadth as well as the length of the inferior articular facet, the breadth of the superior articular facet and the difference of posterior arch thickness at the site of vertebral artery groove were more on the left side as compared to the right side. Conclusion: All the differences that we got are statistically significant. There is also a significant linear association between each of the parameters studied. These asymmetries may be of help to those choosing the different sizes of the implants to be used and the lengths of the incisions that are to be given in the craniovertebral region and to those concerned with manipulative and physical therapy. Furthermore, these differences may be explained by the handedness of an individual, which influences the intraosteal asymmetry in a characteristically distinct manner, which needs to be confirmed or refuted in a further study.
The aim of the present study was to determine the prevalence of interparietal bone in North Indian population and also to observe its shape. Material and methods: 84 adult human dried skulls were obtained from the osteology lab of the Department of Anatomy, KGMU Lucknow, to note the prevalence and various shapes of interparietal bone in North Indian population. Results: Out of the 84 adult human dried skull bones examined, 12 (14.28%) bones were found to have interparietal bones, out of which 4 (4.76%) were quadrangular, 5 (5.95%) were triangular and 2 (2.38%) were round in shape. Conclusion: The interparietal bone can appear in various forms depending on the ossification centres and their nuclei in this region. Furthermore, by knowing its prevalence, the radiologists will be aware and will not misdiagnose it as fracture of occipital bone.

Aims and objectives: The anthropometry in patients of Dhadgoan in Nandurbar district has not been done so far. So the aim was to correlate the various parameters between sickle patients and the normal people and to show the stunted growth in the patients of sickle cell anemia. Material and methods: 70 patients and 70 normal people from same area were taken for the study. Patients of sickle cell anemia were subjected for anthropometric measurements. Patients’ diagnosis was confirmed by peripheral smear sickling test and paper electrophoresis. Measurements like height, length of hand, and foot were taken with calipers and tape. The data was analyzed using means and standard deviation and by using unpaired t test. Results: Height – The age group of 2–6 and 6–12 yrs do not have significant result but age group of 12–18 yrs and 18 yrs above group showed significant result. Hand length – Age group of 2–6 yrs, 12–18 yrs and 18 yrs and above showed significant result but group of 6–12 yrs showed no significant result. Foot length – All the age groups except 6–12 yrs showed highly significant result. Conclusion: Usefulness of the anthropometry is to show the growth retardation in sickle cell anemia patients by taking body measurement. Mainly our study was conducted in the tribal area of Maharashtra. Almost all the parameters show the significant growth retardation in sickle cell anemia patients. Our study is helpful not only for pediatricians but also for physicians for the prognosis and treatment of sickle cell anemia patients.

Aims and objectives: The interparietal bone can appear in various forms depending on the ossification centres and their nuclei in occipital region. Review of literature reveals that the prevalence of interparietal bone ranges from 0.8% to 6.6%. This bone, if present, gives false appearance of fracture on roentgenogram and may lead to complications during burr hole surgeries.
