Introduction Height is defined as distance between vertex of head and surface. Reconstruction of the stature from various parameters is quite valuable for identification & for establishing the individuality of a person. Aims and Objectives The present study was done to determine the stature from parameters of upper limb & lower limb of individuals having age group of 1725. Materials and Methods Authors have studied 213 male and 87 female, healthy subjects in Department of Anatomy, IMS & SUM Hospital, Bhubaneswar. All individuals were measured for height and arm, forearm, hand & foot length. Observation and Results The data thus obtained has been tabulated & subjected to statistical computation to derive the regression equations. Conclusion The results concluded that height has a definite correlation with the parameters. This conclusion is of utmost importance to anthropologist and forensic experts for estimation of stature from mutilated, decomposed or fragmentary skeletal remains. Keywords: Estimation, parameters, limb

Introduction   
Anthropometry is a series of systemized measuring techniques that express quantitatively the dimensions of human body and skeleton. Anthropometry is often viewed as a traditional and perhaps the basic tool of biological anthropology, but it has a long tradition of use in forensic sciences. Its use is increasing day by day in various fields especially in the discipline of forensic medicine. The significance and importance of craniometry, somatometry, cephalometry and osteometry in the identification of human remain have been described and a new term "Forensic Anthropometry" is coined. Relationship that exists between different parts of body and height has been of great interest to anthropologists, forensic and medical scientists for many years. This is because of the increase in the number of catastrophic events causing mass death from natural and manmade errors. Such disasters like flooding, tsunamis, earthquakes, plain crashes, train crashes, terrorist attacks usually requires the identification of victims from fragmentary and dismembered human remains. The lengths of some long limb bones were found to be highly correlated with stature ^{[1]} . In the present study, an attempt has been made to estimate the height not only from hand length, but also from arm length, forearm length and foot length.
Material and methods   
The current research was conducted using students of IMS & SUM Hospital, Bhubaneswar, Odisha, India. It was undertaken in the Department of Anatomy with 300 students as subjects after ethical clearance. The participants were students of first year M.B.B.S. (213 males & 87 females).
Inclusion criteria for subjects   
 Age should be between 1725 year
 Belong to middle socio economic status
 Should have no skeletal or pathological changes.
Exclusion criteria   
 Those who do not know their age
 Those with skeletal deformity or growth disorders
The study included this age group because as the bone growth stops after 21 year, so the ratio between height & limbs will not change after that age. They were placed on the standard anatomical position with the head on the Frankfurt horizontal plane. All of the measurements were taken from the left side for uniform readings. For the convenience of readers, the dimensions were taken in 1 cm unit with standard anthropometric instruments such as Verniers sliding caliper, anthropometer, measuring tape, scale and wooden base osteometric board.
To ensure accurate results, all the measurements were done by one person while sitting on a low chair to avoid errors that could be caused by discomfort. All subjects who did not know their age and those who had recognized skeletal deformities were exempted from the study. The measurements were repeated to avoid errors. The measurements were taken at a fixed time, between 2.00 pm to 4.30 pm, to eliminate diurnal variation. All measurements were taken by one person to avoid personal errors.
The Parameters taken are   
 Stature: Maximum distance from vertex to floor, maintaining the anatomical position and Frankfort plane.
 Arm Length: Maximum distance from the acromian angle to the external superior border of head of radius.
 Forearm Length: Maximum distance from marked head of radius to the tip of the lateral styloid [Figure 1].
 Hand Length: Maximum distance between the middle point of the line connecting the styloid processes and the tip of 3 ^{rd} digit [Figure 2].
 Foot Length: Maximum distance between acropodion (it is the most forwardly projecting point on the head of the 1 ^{st} or 2 ^{nd} toe whichever is longer when the subject is standing erect on a flat hard surface) to the pternion (it is the most backward projecting point on the heel when the subject is standing upright with equal pressure on both the feet) [Figure 3].

Observations and discussion   
From the [Table 1], it's found that as the height increases, the number of samples in case of females decreases. So the graph becomes like a straight line with a negative slope. So, maximum number of samples is found at a height range of 150155 cm. But in case of males, the graph becomes bell shaped i.e. maximum number of samples are found in the middle at the height range of 165170 cm [Figure 4].

[Table 2] shows average arm length of male persons having height ranging from 150180 cm which are again subdivided into six sub groups each having a range of 5 cm [Figure 5]. The standard deviation and standard error were calculated. Regression equation from the above table was calculated to be
Y = −104.44 + 8.083x
Where Y = Height of the individual
−104.44 = Intercept
8.083 = Slope
X = Arm length of the individual
[Table 3] shows average arm length of female persons having height ranging from 150180 cm which are again subdivided into six sub groups each having a range of 5 cm [Figure 6]. The standard deviation and standard error were calculated. Regression equation from the above table was calculated to be
Y = −206.96 + 11.52x
Where Y = Height of the individual
−206.96 = Intercept
11.52 = Slope
X = Arm length of the individual
In a study by Nath, Rajni and Chhibber ^{[2]} on 302 Punjabi females of Delhi, derived regression formulae for estimation of stature from upper arm length was, 82.68 + 2.29 (UAL) whereas in present study the regression equation for females was 206.96 + 11.52(UAL). Similarly, Nath and Krishan ^{[3]} also formulated multiplication factors for reconstruction of stature from upper arm length in 276 Hindu (Baniya) females of Delhi, having age range from 1522 years. The multiplication factor was found to be 4.95 whereas in this our study the multiplication factor in Eastern Indian females was 4.97. Nath, Garg and Krishan ^{[4]} also conducted a study on 160 male Rajputs of Tehsil Chakrata; district Dehradun, Uttar Pradesh in age range of 1635 years. The multiplication factor was 5.12 whereas in comparison, the multiplication factor from upper arm length in male Eastern Indians was 4.97. Anand and Nath ^{[5]} conducted a study on Rajput males and females of Pauri Garhwal and calculated multiplication factor for upper arm length to be 5.59 for males and 5.89 for females. In present study the multiplication factor for upper arm length came out be 4.97 for males and 5.001 in females. Another study done by Jain and Nath ^{[6]} on 132 male Brahmins of Kumaon in age range of 1719 years and the multiplication factor was calculated to be 5.44 whereas in comparison in present study the multiplication factor in North Indian males was 4.97.
In present study, the linear regression equations was also calculated for estimation of stature from upper arm length in Eastern Indian males which was
S = 104.44 + 8.083 X arm length.
From the [Table 4], we see that, as the height increases, the arm length of both male and female also increases [Figure 7]. The difference was found to be decreased up to sub group 160165 cms then increases in subsequent groups. There were no female found in 175180 cms height group.

Nath et al. ^{[7]} conducted a study to reconstruct stature on basis of percutaneous length of forearm bones on 199 Munda (110 males and 89 females) of Midnapur district, West Bengal in age group of 1830 years. The mean value of stature in males was 156.19 cm whereas in this study it was 168.49 cm. Similarly the mean value of stature in Munda females was 148.64 cm whereas in East Indian females were 156.54 cm. The mean value of forearm length in Munda males and females was 24.60 cm and 22.85 cm respectively and in East Indian males & females was 24.36 cm and 22 cm respectively.
Another study conducted by Jain and Nath ^{[8]} on 132 male Brahmins of Kumaon in age range of 1719 years, the mean value of stature was found to be 161.3 ± 6.32 cm compared with East Indian males which was 168.49 ± 5.1 cm. The mean forearm length in Brahmins was 24.61 ± 2.0 cm whereas in present study was 24.36 ± 1.32cm. The Multiplication factor calculated in Brahmins was 6.50 whereas in North Indian males were 6.91.
In a study by Ilayperuma et al. ^{[9]} on 258 medical students (140 males and 118 females) of faculty of medicine, university of Ruhana, Galle, Srilanka in age range of 2023 years, the mean value of stature in males and females was calculated as 170.14 ± 5.22 cm and 157.55 ± 5.75. Compared with East Indian males and females height was found to be 168.49 ± 5.1 cm and 156.54 ± 7.32 cm respectively. The forearm length in Srilankan male and females was 27.56 ± 1.30 and 25.11 ± 1.24cm respectively compared with East Indian male and females was 24.36 ± 1.32 cm and 22.00 ± 2.13 cm respectively. The linear regression equation derived by Ilayperuma, Nanayakkara and Palahepitiya in males: S = 97.252 + 2.645 (Forearm length) in females: S = 68.777 + 3.536 (Forearm length) whereas in this study, for males = 254.03 + 17.45 (Forearm length) & for females = 32.16 + 5.66 (Forearm length).
Nath, Garg and Krishan ^{2} studied on 160 male Rajputs of tehsil Chakrata, district Dehradun, Uttar Pradesh in age range of 1635 years and calculated mean stature to be 164.4 ± 9.22 cm. In North Indian males it was 168.49 ± 5.1 cm. The mean value of forearm length in Rajputs was 23.8 ± 1.49 and in East Indian males was 24.36 ± 1.32 cm. The multiplication factor in Rajputs was 6.92 and in East Indians were 6.91 respectively.
From the [Table 7], we see that, as the height increases, the forearm length of both male and female also increases. The difference was found to be decreased upto sub group 165170 cms then increases in subsequent groups. There were no female found in 175180 cms height group.

To compare the results of this study, with the studies done by various other scientists, a table is given below.
From the [Table 10], we see that, as the height increases, the hand length of both male and female also increases. The difference was found to be decreased upto sub group 165170 cms then increases in subsequent groups. In 170175 group the hand length higher than male. There were no female found in 175180 cms height group [Figure 12].  Figure 12: Mean values of hand lengths in male and female subjects of different heights.

In a study by Jasuja et al. ^{[15]} and later by Singh and Phookan ^{[16]} , measurements were taken from males of four different ethnic groups in India. Also works of Giles et al. ^{[17]} , Robbins and Quamra et al. ^{[18],[ 19]} has been conducted for height estimations from foot and shoe measurements by means of a statistical method. Saxena et al. ^{[20]} conducted a study in Nigeria using 100 male medical students between the ages of 20 and 30. They took right foot lengths for calculating height & estimated the formula: height = 67.4929 ± 3.9755 X right foot length. Patel et al. ^{[13]} did a study on the students of Gujrat region to calculate correlation between foot length & height. The regression equation they calculated for males = 75.45 + 3.64 x foot length. For females = 75.41 + 3.43 x foot length. However, in this study, the regression equation for males was found to be Y = 27.77 + 7.695 X foot length & for females, Y= 77.85 + 3.58 X foot length.
Nath et al. ^{[21]} formulated multiplication factors for reconstruction of stature from foot length in Rajputs & Brahmins in Srinagar, Garhwal (U.P.). The multiplication factors were 6.87 & 6.64 for Rajput & Brahmin males & 6.72 & 6.68 for Rajput & Brahmin females respectively. In this study, the multiplication factors found to be 6.68 & 6.75 for males & females respectively.
From the [Table 13], we see that, as the height increases, the foot length of both male and female also increases. The difference was found to be increased up to subgroup 160165 cms then decreases in subsequent groups. In 170175 cm group the hand length higher than male. There were no female found in 175180 cms height group [Figure 15].  Figure 15: Mean values of foot lengths in male and female subjects of different heights.

Conclusion   
From the present study, it's found that some multiplication factors along with regression equations can be calculated for estimation of stature from different parameters of extremities in the population of Eastern India. It may be helpful for researchers who work in this area especially in the various medical disciplines, anthropologists and security personnel.
