Background: Ballet produces much stress on bones in the feet of ballerinas. Monitoring and detecting talus bone deformation is important for their quality of health and profession. Objectives: To determine differences in the talus bone between ballerinas and sedentary women. Methods: We evaluated biometric differences in the talus bone of 5 ballerinas referenced to 5 similar sedentary women recruited into the present study. We acquired 20 multidetector computed tomographic images including right and left feet. Semiautomatic region-based image processing using 3D-Doctor (Able Software Corp) was used to create three-dimensional (3D) virtual models of the talus bones. Biometric measurements were made on the 3D models and statistical analysis conducted. Results: The mean talus bone length of ballerinas was 3.37 cm (SD 0.12; range 3.11 to 3.52). The talus bone length of sedentary women was 3.29 cm (SD 0.16; range 3.04 to 3.65), and tended to be shorter than that of the ballerinas (P = 0.08, t test). However, the test was insufficiently powered. The mean volume of the talus bones from the ballerinas was 24.8 cm3 (SD 0.83) and smaller than that from the sedentary women, 26.9 cm3 (SD 1.25) at P < 0.001 (t = 4.38, 18 degrees of freedom. Difference 2.1. Two-tailed 95% confidence interval for difference of means: 1.08 to 3.08). We found less variation in the feet of ballerinas than sedentary women. Conclusions: Volumetric measurements show that feet of ballerinas are smaller and retain similar shape and size than the irregular feet of sedentary women.

In this study, semi-automatic region-based digital image processing techniques were used to create 3-dimensional (3D) virtual model of talus bone. 5 ballerinas and 5 sedentary women have voluntarily been involved in to the study. Total 20 right and left feet have been used which have been taken from the multidetector computed tomography (MDCT). We used 3D Doctor Software in this research. Image preprocessing, segmentation and 3D modeling steps were done respectively. Volume, area and length based various statistical ratios were computed according to the measurements. The comparisons have been accomplished by using these ratios for sedentary and ballerinas. As an outcome, some differences were found in talus of ballerina and sedentary women. We hope that the results from the biometric and reconstructive techniques carried out in this study will contribute to the present knowledge in orthopedics and digital image processing in this area.
