Morphometric Study and Sexual Dimorphism of Percutaneous Tibial Length in Indian Race

Background: “Anthropometry” includes the different techniques which express the human body and its parts in quantitative manner. Hence, this technique is considered as one of the useful and most applicable, non-invasive and also inexpensive technique worldwide. For the establishment of size of the body and also in sexual dimorphism this technique has been used by the anthropologist for many years. Aim: this study is undertaken to show sexual dimorphism in percutaneous tibial length in Indian race. Methods: The study was carried out on 200 subjects (100 male and 100 female) among the population of India. Percutaneous tibial length was measured with the help of spreading caliper. The data was collected and analyzed statistically. Results: Our study shows no significant difference between the Right and left PCTL in male and female among Indian races. Mean right PCT: Male ‐ 37.82±1.99, Female ‐ 34.84±1.91, Mean left PCT: Male ‐ 37.79±1.98, Female ‐ 34.79±1.89. The percutaneous tibial length was significantly high in males as compared to females. Conclusion: The present study reveals that there is no statistical significance difference occurs between the right and left percutaneous tibial length among male and female. It also shows that the percutaneous tibial length of male is significantly higher than female in the Indian race.

Estimation of height from percutaneous tibial length among South Indian population

Introduction: The origins of anthropometry are very ancient. As long ago as old Egypt and Greece. The word ‘Anthrapometry’ was first used in the seventeenth century by a German physician J. Sigismund Elshwltz(1623-88). Materials and Methods: This present study was conducted on 300 Medical, Dental and Parmedical male students of Vinayaka Missions University, Salem, Tamil Nadu. The age of the students ranged from 20-23 years who belonged to South Indian region. The length of the tibia is defined as the direct distance between the medial most superficial point on upper border of medial condyle and tip of the medial malleous. The study subject was asked to sit with knee placed in the semi flexed position and the foot partly inverted to relax the soft tissues and facilitate bony landmarks prominent. Then, the bony landmarks are measured with the help of spreading callipers. Further, the measurement is confirmed by using measuring tape. Height was measured by measuring crown to heel standing erect posture with anthropometer. Measurements of length of right and left tibia were taken separately for calculation. Statistical analysis was done using SPSS software. Observations and Results: Linear regression formula was derived for estimation of height from percutanous length of right and left tibia. Y1=94.5+1.8X1 Y2=88.55+1.95X2 Where, y1 and y2 are estimated heights from length of right and left tibia. X1 and X2 represent the length of right and left tibia respectively. Conclusion: Regression formula obtained can be used for the estimation of height from the tibia bone in south Indian population. Keyword: Tibia, Stature, Forensic, Anthropology

Estimation of stature from percutaneous length of tibia in the population of Birgunj, Nepal

Background: Stature estimation is one of the important parameters in establishment of the identity of a person. As said “Identification is an individual’s birth right”, stature of an individual is an inherent character. Mass disasters like aircrash, terrorist attacks etc. are quite frequent these days because of which dismembered body parts are being frequently brought to the medico-legal experts for generating data for identification.Objective: The objective of this study is to estimate the stature from percutaneous tibia length (PCTL).Methods: This prospective study consisted of 150 males and 150 females between the age group of 20 to 30 years, born and brought up in Nepal. The duration of study is one year from October 2012 to October 2013. The parameters measured were stature and percutaneous tibia length. To find out the correlation of percutaneous tibial length with that of the height and to evolve a regression equation formula necessary statistical evaluation has been done on the data obtained from 300 adult participants comprising of 150 males and 150 females. By using the regression equation formula so derived the height of an individual can be calculated by the help of percutaneous tibial length. The data were analysed using Statistical Package for Social Sciences (SPSS) version 11. P value less than 0.05 was considered as a significant.Results: It was found that a significant positive correlation existed between the stature and percutaneous tibial length with a correlation coefficient (r) of 0.562 in males and 0.71 in females and p value <0.001. Stature was estimated from PCTL using simple regression analysis Stature (cm) = 88.898+2.027 * PCTL (cm) for males and Stature (cm) = 75.954+2.253 * PCTL (cm) for females.Conclusion: A highly significant correlation of stature was observed with percutaneous length in both sexes. The result of this study would be useful for anthropologists and forensic medicine experts. Stature can be estimated from PCTL using simple regression analysis.DOI: http://dx.doi.org/10.3126/jkmc.v3i2.11227Journal of Kathmandu Medical CollegeVol. 3, No. 2, Issue 8, Apr.-Jun., 2014Page : 58-62

Stature Estimation Using Per-Cutaneous Tibial Length in People of Gwalior Region

Introduction: Stature estimation is an important part of the identification process of human skeletal remains or body parts to establish individuality of an unidentified dead, body or any mutilated part of such body by the Medico-legal expert.. Aim: The present study made an attempt to estimate the stature from per-cutaneous tibial length (PCTL) by formulating simple regression equation and multiplication factor (M.F.) for people of Gwalior region. Method: A random sample of 270 male and 270 female students of G.R.Medical College, Gwalior between the age group of 18-21 years was chosen. PCTL of right and left side were measured with the help of spreading caliper. Stature was estimated from PCTL statistically using simple regression analysis and M.F. Result: On computing the data, the mean PCTL for male was found to be 38.24±2.343cm which was significantly (p<0.0001) greater than female which was 36.064±2.464cm. The observed height was 164.5±8.257cm and 155.3±5.854cm for male and female respectively. The regression formula derived for male was y0=105.971+1.53 x(PCTL) ± 7.452 and for female was y0= 103.76+1.43 x(PCTL) ± 4.69. The M.F was 4.302 for male and 4.306 for female. A significant positive correlation exists between the stature and PCTL using simple regression analysis and M.F. Conclusion: It was concluded that the stature of a deceased person whose only body part available is a mutilated leg, can be determined by using the formula derived from the present study fairly accurately to some extent. Thus the data of this study is recommended in anthropological studies for stature estimation amongst the ethnic group under study.

Stature and Percutaneous Tibial Length - A Correlational and Comparative Study in Sex of Gujarat

One of the primary characteristic for the identification of a person is the stature of the person. After the age of 21 - 25 years, the dimensions of the skeleton remain unchanged and the ratio in size. Of different parts to one another is also considerably variable in different individuals. In case of dismembered body parts, stature can be estimated on the basis of ratio of the different parts. In this paper, attempts are made for the estimation of the stature of native of Gujarat state at AMC MET Medical College, Ahmedabad using Percutaneous tibial in year 2009–10. Tibial length was taken from medial condyle to the tip of medial malleolus with the knee semi flexed and foot partly inverted.

A Study of Bilateral Asymmetry of Tibia in Living

There have been many studies of asymmetry both morphological and physiological. In the study of human bones, the result appears to be more definite and all of the reports seen to indicate at least a degree of predictable asymmetry. The objective of the study was to find out the bilateral asymmetry of lower limb by measuring the percutaneous length of tibia in living. The material consisted of 440 individual in which male and female constituted the equal number between the age group of 18 to 24 years. This group comprises the admixture of students admitted from all over the country. Measurements were taken at a fixed time to avoid diurnal variations. Length of both side of tibia was recorded with vernier caliper. The observed data was subjected to statistical analysis. The result obtained indicated the left tibia found to be longer than the right tibia when both sexes considered together. When considered the both sexes separately, left tibial length was more than right in male and right tibial length was more than left tibial length in female.

Estimating stature from percutaneous length of tibia and ulna in Indo-Mauritian population

Stature estimation from percutaneous body measurements forms part of forensic anthropological analysis for the purpose of identification. This study is aimed at modeling the stature on the basis of percutaneous tibial and/or ulnar length in human subjects comprising of Indo-Mauritian population. The study was conducted in the Department of Forensic Medicine and Toxicology, SSR Medical College, Mauritius on 180 young and healthy students comprising of 90 males and 90 females in the age group ranging from 18 to 28 years. The measurements were taken by using standard anthropometric instruments. It is remarked that tibial as well as ulnar length show a linear relationship with the stature, where stature is normally distributed. However, it is required to transform the measurements on stature to obtain appropriate regression equations. Moreover, since ulna and tibia are significantly correlated, it is recommended to use the sum of the ulnar and tibial length to estimate stature, in case both are available for an individual. Our regression models are sufficiently validated and highly efficient.

Estimation of human body built in Egyptians

Identification of an unknown body and prediction of growth from specific body measurements are very important tasks in the fields of physical anthropology and forensic medicine. Height and weight are two factors among others required to establish individuality of an unidentified body. In the present work, an attempt has been made to calculate the stature and weight from percutaneous tibial length and bimalleolar breadth. The study was carried out on 1000 living Egyptian individuals comprising 500 males and 500 females; their age was between 19 and 21 years. A significant positive correlation between stature and tibial length in both sexes was recorded. The coefficient of determination showed that 56% of variation in stature was due to tibial length and bimalleolar breadth in males, while in females the coefficient of determination was 23%. On the other hand, the coefficient of determination for weight showed that 11% of variability in weight was due to tibial length and bimalleolar breadth in males, while in females it was 5%. Linear regression analysis was done for all variables in all cases. The regression equation formulae are helpful in the estimation of stature and weight of the deceased from tibial length and bimalleolar breadth when leg or foot is the only portion available for autopsy examination.

Prediction of height from percutaneous tibial length amongst Oriya population

Abstract Establishing individuality on the mutilated part of a dead body is quite a difficult work in forensic medicine. Among the factors required, to establish individuality of an unidentified dead body or any mutilated part of such dead body, height is one of them. In the present work an attempt has been made to calculate the height from the percutaneous tibial length (PCTL) as measured by surface anatomical landmarks that is between the most prominently palpable part of the medial condyle of tibia and tip of the medial malleolus. To find out the relationship of PCTL with that of the height and to evolve a regression equation formula necessary statistical evaluation has been done on the data obtained from 1000 adult individuals comprising of 500 males and 500 females. By using the regression equation formula so derived the height of an individual can be calculated by the help of PCTL, when only the mutilated ley portion is available for autopsy examination.
