MORPHOMETRIC STUDY OF TALUS BONE IN SOUTH COASTAL POPULATION

Background: The talus bone is the second-largest tarsal bone. Morphometric study of right and left talus is necessary to know the right–left symmetry for the radiologists and orthopaedic surgeons for planning the surgeries of talus and implants during injuries and fractures . Hence, this study was done to observe the facets of the inferior surface of the talus and to measure the morphometric parameters of the talus. Methodology: This cross-sectional study was carried out on a total of 100 dry adult human tali (47 of the right side and 53 of the left side). Morphologically, the types of articular facets on the head of the talus were assessed and classified as done by Boyan et al. as -Type A1, Type A2, Type A3, Type A4, Type B, and Type C. Morphometric evaluation of talus was done with the help of digital vernier caliper, and anteroposterior distance (length), maximum transverse width, vertical height of talus, length of sulcus tali, width of sulcus tali and depth of sulcus tali were measured. Statistical analysis was performed, and data were expressed as mean, minimum, maximum values, and standard deviation. In the Results: present study, Type A1 facet was found in 28.43% of the talus, in 28.43% of Type A2, in 0.98% of Type A3, in 14.71% of Type A4, in 4.90% of Type B, and Type C facet in 22.55% were found. The mean length, width, and height of the talus were 54.18 ± 4.14 mm on the right side and 54.34 ± 3.97 mm on the left side, 38.80 ± 3.51 mm on the right side and 38.77 ± 2.86 mm on the left side, 29.25 ± 2.61 mm on the right side and29.89 ± 3.80 mm on the left side. The width, length, and depth of sulcus tali were 7.20 ± 2.10 mm on the right side and 7.34 ± 1.93 mm on the left side, 18.14 ± 3.20 mm on the right side and 18.51 ± 2.89 mm on the left side, 5.96 ± 1.32 mm on the right side and 6.94 ± 1.25 mm on the left side respectively. HNL of talus was 26.00 ± 2.41 mm on the right side and 25.25 ± 2.56 mm on the left side. There are a minimal difference in the valu Conclusion: es width of the talus, head neck length and also the depth of the sulcus tali of the talus bone. Hence, the measurement of this study may help the surgeons to choose the appropriate size of the prosthesis for talus implantation surgeries.
