Abstract

PURPOSE
To investigate the measured values of the talus in Koreans.
MATERIALS AND METHODS
We measured 88 tali from 44 cadavers that have been donated between December 2012 and December 2015. Of the cadavers, 27 were male and 17 were female. Their mean age was 73 years. The length and width of the talus were measured using a digital goniometer and vernier caliper.
RESULTS
The values of cadaveric measurement, mean maximal width and length, width and length of the dome anterior, width and length of the posterior facet, height and length of the trochlear medial facet, and height and length of the trochlear lateral facet were 43.6±2.6 mm, 56.5±3.3 mm, 32.5±2.0 mm, 42.2±2.7 mm, 22.2±2.2 mm, 34.7±2.0 mm, 15.3±1.3 mm, 33.3±2.9 mm, 25.3±3.3 mm, and 30.8±2.4 mm for men and 38.9±1.6 mm, 53.6±2.4 mm, 27.9±2.1 mm, 37.4±3.2 mm, 20.6±0.8 mm, 31.9±1.2 mm, 13.6±2.6 mm, 28.4±2.5mm, 24.9±2.1 mm, and 28.9µ1.4 mm for women, respectively. The size of the talus showed an accuracy of 86% when anteroposterior diameter was greater than 59 mm. A difference in the size of the right and left talus was not observed. The mean inclination and declination angles were 24.4°±4.2° and 28.2°±5.4° for men, and 24.6°±3.6° and 24.7°±6.7° for women (p=0.980, p=0.018), respectively, at least 15°, which showed a big difference for every object up to 37°.
CONCLUSION
This paper, to the best of our knowledge, is the first study to measure the talus in Koreans. There were differences by gender and ethnicity in the in measured talus values. The measurements were smaller than European-Americans and greater than Japanese.
