Background: In the formation of talo calaneo navicular joint ,congruence of articular surfaces of  talus, navicular and calcaneum is very important to maintain the stability and in the distribution of body weight to the remaining tarsal bones. Aim: To prepare morphometric data of talar surfaces (posterior surface) of body of navicular bone, to find if there is any difference between both the sides (right and left) of measurements , range of measurements and it’s mean value of measurements in telangana region people. Material and Methods: The study was conducted on  47 (right 21 left 26)  dry Human adult  navicular bones  of undetermined gender and age separated into right side and left side bones. Each right and left Human navicular bone were assigned a serial number. On the talarsurface (posterior surface) surface, vertical length (height) of talar surface and  transverse length (breadth) of talar surface of navicular bones were measured. The Data was tabulated and Analysed.  Results: On the Posterior Articular surface (talarsurface), the range of vertical length (height)  of navicular bone  were 16mm to 27mm on Right side and 16mmto28 mm on Left side.The range of transverse length (breadth)  of navicular bone  were 23mm to 30mm on Right side and 24mm to 32mm on Left side. The mean values of vertical length (height) and  transverse length (breadth)  of talar surface of navicular bone  were 19.7mm and 25.6 mm on Right side respectively. The mean values of vertical length (height)  and  transverse length (breadth) of talar surface of navicular bone were 20.0mm and27.3mm on Left side. Conclusion:The talar articular surface measurements of opposite navicular bone can be used as a control during navicular bone replacement surgery, it may help surgeons to plan pre–operatively to design accurate navicular bone prosthesis and  implants.
