Objectives: Talus is the highest of the tarsal bones of the foot and is the keybone of the foot arch. Talus supports body weight transmitted via tibia and distributes it to other tarsal bones. For this reason, it is thought that it may be effective in many deformities encountered in the foot. In this study, morphometric dimensions, angular features and facies articular calcanea types of talus were investigated.To identify the anatomical variations that can be seen in the talus, to identify the types of joint faces and the orientation differences between them, to define the morphometric features of the talus. Method: The study was carried out on 50 dry talus (30 right and 20 left) of unknown sex in anatomy laboratories of Selcuk University and KTO Karatay University Faculties of Medicine. In the morphometric measurements, total talus length, width and height, height of caput tali, length of collum tali, length and width of trochlea tali, the length and width of the art. subtalaris were measured using digital calipers. In addition, vertical and medial neck angles were measured and facies articular calcanea types were determined Results: The mean talus length in the examined dry materials was found to be 55,47 (47,53-65,30) mm; width 41,56 (34,49-48,96) mm; height 31.70 (25,34-38,63) mm. The mean vertical neck angle was calculated as 95.08 ° (88 ° -103 °), medial neck angle was found as 73.24 ° (64 ° -84). According to Nozaki et all.'s (2016) classification of subtalar joint faces, 7 types (14%) of B1 type, 13 (26%) type B2, 18 (36%) type C, 3 ) Type D, E1 type in 6 (12%) and E2 type in 2 (4%). It was found that only 1 subject (2%) was type A. Conclusion: The results of the study may be a reference foot treatment of talar injuries in clinical practice, such as the design of total ankle replacement components and surgical reconstruction of talar articular structures. Keywords: Talus, morphology, morphometry.
