Introduction Determination of age is prerequisite for personal identification in living as well as dead.age estimation becomes a valuable tool to assist in administration of many civil and criminal procedure. Questions of juvenility are often a questions that has to be answered correctly in connection with criminals of younger age group.in cases where biological study of maturity of a child has to be performed to access the development of a child, Age estimation is of paramount importance. Age estimation in the maturing skeleton is dependent upon three processes; the appearance of primary and secondary ossification centres, the growth of these centres and the timing of fusion of primary and secondary centres. these appearances and changes have been well documented both in dry bone and radiographic studies. Age determination of an individual from appearance & fusion of centres is a well-accepted fact. After puberty the process of growth in length of the long bones stops at different ages in different parts of different long bones. This stoppage of growth process is indicative on x-ray examination by fusion of the epiphysis with its respective diaphysis, or can say secondary centre with primary centre. This process is completed by the age of 22 years as described by various authors. The minor differences in the age of fusion could be due to effects of changes in climate, economic, hereditary, dietic conditions or involving some unknown factors [29]. The epiphyseal union during age periods is remarkably constant for particular epiphysis. Estimation of skeletal age from radiograph is a matter of everyday occurrence in every part of the world. the present study has been carried out retrospectively to explore the pattern of epiphyseal union in the bones distal end of Radius and Ulna growing population of Western Rajasthan. ~ 8 ~

AIMS and Objectives The present study is conducted in the Department of Anatomy, DR.S. N. Medical College, Jodhpur (Rajasthan) with following Aims and Objectives:- 1. To estimate age from epiphyseal fusion around wrist joint. 2. To assess age specific difference in epiphyseal fusion at wrist joint. 3. To know the factors influencing epiphyseal fusion like race, sex, geographical distribution and nutritional status. 4. To assess if there is significant difference between the bone age of today s population with that of the standards. Material and Method The present study were carried out on 100 healthy students (50 males&50 females). The subjects aged between 16-22 year of MBBS first year, Dr. S.N. Medical College, Jodhpur (Rajasthan). Ethical committee permission WAS obtained -Consent of parents obtained Inclusion criteria Apparently normal healthy children between age group of 16-22 years. Children who have documentary evidence for date of birth. Date of delivery details, birth certificates, school records. Exclusion criteria Subjects with criteria affecting the growth of bones and epiphyseal fusion like congenital deformities, fracture cases, chronic illness, on steroid therapy etc. were excluded from the study. The pro-forma of all the students who participated in this study was prepared and filled up with the details provided by the students and their parents along with their radiological finding. Chronological age, Height, weight, general physical development and diet were recorded in all cases and the menstrual history of girls was also accounted for. 1. Stage 0: non-union A dark black radiolucent line seen between the area of diaphysis and epiphysis. 2. Stage I: union in progress-(i) Gap between diaphysis and epiphysis begins to decrease but complete un union does not occur. 3. Stage II: complete union with white dense line: (II) union between diaphysis and epiphysis is complete but white dense line still visible at diphysio-epiphyseal junction. 4. Stage III: complete union without any white line. (III) union between diaphysis and epiphysis completed and no white dens line visible at diphysio-epiphyseal junction. The findings are recorded on specially designed pro-forma, tabulated, analyzed and compared with similar studies by different authors. Observation & Results The present study was carried out on 100 healthy students of MBBS (50 males&50 females). The subjects aged between 16-22 year of Dr. S.N. Medical College, Jodhpur (Rajasthan). Data is tabulated and statistically analysed below. The following table shows age & sex wise classification of the samples. Table 1: Age and Sex wise classification Male Female 16-17 13 8 21 17-18 9 12 21 18-19 9 12 21 19-20 8 8 16 20-21 6 5 11 21-22 5 5 10 50 50 100 Radiological specification X rays of lower end of left hand in AP view were taken. The left hand should be faced downward, extended, and flat on the x-ray cassette to generate a posterior-anterior radiograph of the hand. The axis of middle finger should be in direct line with the axis of the forearm, and the centre of the x-ray tube above the distal end of the third metacarpal. The fingers are spread so they are not quite touching, and the thumb is rotated out to a natural position of around 30 degrees to the first finger. the x-ray beam should be perpendicular to the cassette. The x-ray is usually performed of 45-60kVp.x-ray. All 100 subjects of either sex were grouped into 4 agegroups as follow 1. Group I: 16-17 years 2. Group II: 17-18 years 3. Group III: 18-19 years 4. Group IV: 19-20 years 5. Group V: 20-21 years 6. Group VI: 21-22 years The findings of epiphyseal fusion are divided into 4 stages. ~ 9 ~ Fig 1 1.

Table 5&6 Epiphyseal fusion at distal end of Radius & Ulna with the shaft (left hand) in Females Fig 4 Fig 5 Fig 6 earlier than this study. As per Yogesh Sharma [19], the age of fusion is 18-19 years in U.P. males which are about one year later than this study. Bajaj [3] recorded the age of fusion to be 16.4 years in Delhi males. Hepworth [17] opined that the age of fusion in Punjabi males is 16-17 years which are on an average one year earlier than the present study. M.J.S Pillai (1936) (SOUTH INDIA) recorded 18 years of age in males and females. Banerjee aggarwal (1998)U.P opined 19-20 Years age of fusion in males and 18-19 years in females. In the present study it is observed that fusion of lower end of ulna in males complete in 19-20 years. These observations are similar to the observation done by Lall & Nat. Observations are differing from the following observation by different authors. Galstaun [13], Hepworth [17], Sharma Yogesh [19], Goel MR, Dutta Sumanta [15] studies showed early age of fusion at lower end of ulna while Loomba study showed late age of fusion. In the present study it is observed that fusion of lower end of ulna in females complete in 18-19 years. These observations are similar to the observation done by others. Observations of present study Fig 7 were different from the Galstaun, S.M. Hepworth, Pryor, Sharma Yogesh, Goel MR & Dutta Sumanta observations, which showed Discussion early age of fusion at lower end of ulna. In the present study it is observed that fusion of lower end of Radius in males complete in 18-19 years and 18-19 years in Conclusion females. Galstaun G [13] from his study on Bengalese males opined To establish exact identity of an individual age determination is that the complete union occurred at 16 years which is about 1-2 essential not only in cases of living but also for the dead too. Age years earlier with the results of this study. Apurba Nandy recorded has to be determined not only for identification purpose but also the latest time of fusion as 15-16 years which are at least 2 years for various civil and criminal purposes. Determination of age ~ 11 ~

presents a task of considerable importance from the view point of the administration of justice. It is not possible to enunciate a hard and fast rule for age determination from this union for the whole India because India is composed of areas which differ in climatic, dietetic and disease factors which affect skeletal growth. Age Determination of an individual from appearance & fusion of ossification centers is a well-accepted fact. Age can be established by rontgenography of skeleton from the time of its appearance about the 20 week of gestation until early adulthood with considerable accuracy. As we all know that earliest centers of ossification appear at the end of 2nd month of pregnancy. At the 11th intra-uterine week there are 806 centers of bone growth which is reduced to 450 centres at birth & ultimately an adult has a total of 206 bones. The epiphyseal union during age periods is remarkably constant for particular epiphyses. Estimation of skeletal age from radiographs is a matter of everyday occurrence in every part of the world. According to the present study epiphyseal fusion at lower end of Radius occurs in advance of the lower end of ulna and the difference is about one year. According to the present study: The Mean age for complete epiphyseal fusion of lower end of Radius among the people of Western Rajasthan is 18.78±1.47years for Males and 18.57±1.33 years in Females. Mean age for complete epiphyseal fusion of lower end of Ulna in Males 19.84±0.83 years and for Females 18.69±1.39 years (p value<0.05).
