Introduction: Knowledge of size and shape of proximal end of radius i.e. radial head is necessary for creation of anatomically and biomechanically correct radial head prosthesis. This difference in biome-chanics of circular shape and the elliptical shape of radial head must be taken in consideration in design of radial head prosthesis.2 Further understanding of dimensions of bicipital tuberosity and its angular relationship to radial head is important in pathophysiology of bicepstendon rup-ture as well as to facilitate surgical procedures like reconstruction of biceps tendon, radial head prosthesis and implantation and reconstruction of proximal head trauma.3 Several studies have been published on anatomy using different technical approaches however, most of these studies were conducted with special focus on parameters relevant to radi-al prosthetic design. The purpose of this study was to explore the complex geometry of the prox-imal radius with regard to fracture implant design.4 Methods: Randomly selected 100 right and 100 left dried radii of Adult Human (20 years and above) of unknown gender were studied. The data obtained was analyzed statistically to find out mean, range, SD, standard error and 95% confidence intervals of observations. Box and whisker’s plot are showing the pictorial forms of the observation sat a glance. Results: The mean height, anteroposterior and transverse diameter of head, length of radial neck, length of radial tuberosity, Neck shaft angle of radius, circumference at radial tuberosity of radius were 10.39 mm, 20.21 mm, 19.65 mm 11.62 mm, 19.40 mm, 169.29 degree and 4.78 cm respectively.
