In a demographically diverse, vast and densely populated country like India, the establishment of identity of a deceased assumes great medico-legal importance. It also poses a true challenge to the forensic scientist working in an environment where decomposition and taphonomic process are rapid. Structurally bones resist common degradation and putrefactive changes and remain longer as material for evidential value. Human skeletal remains are found under suspicious circumstances and doctors examining them need to give an opinion in the court of law. Forensic experts are often consulted regarding identification of skeletal remains. One of the important data for identification is the stature. The estimation of skeletal samples, for age, sex and stature are vital when found from sites in mixed lot. For this purpose, a technique will be highly appreciated for reconstruction of total length of long bones from their fragments. This current pilot investigation was designed to estimate the total length of radius using its fragmentary bone length in a population specific study thus in turn to employ them in stature formulae for population specific cases to estimate the final stature of the individual. After getting institutional ethical committee clearance, the study over 57 radii revealed linear equation where total length of radius was used as dependent variable and the different fragmentary length being the independent variables.

The study over nigerian population included 40 radius bones of unknown sex which were collected from University of Lagos. 9 parameters were taken into consideration. The distal breadth, sagittal diameter at mid-shaft, transverse diameter at mid-shaft (TDM), vertical radial head height (VRHH), maximum head diameter (max. HD), and minimum head diameter (min. HD) were measured using digital vernier caliper while the circumference of the radial head and the circumference at the radial tuberosity were measured using an anthropometric tape. Measurements were taken to the nearest cms. Right and left bones were compared using student's t-test and Pearson's coefficient was used for correlation. SPSS version 17 was used for statistical analysis. The mean length of the right radius was 26.3 ± 1.6 cm while that of left was 25.8 ± 1.9 mm. The mean differences were not statistically significant. The following equations were thus obtained: Right = 20.537 + 2.758 Max. HD; Left = 17.760 + 2.648 Max. HD + 2.922VRHH; Both = 13.637 + 5.148 TDM + 2.288 4 Max. HD.
