Abstract :Purpose: This study aims to analyze the shape and morphometric features of the obturator foramen insert ignore into journalissuearticles values(OF); in dry human bones. Methods: Forty-six insert ignore into journalissuearticles values(Right:15, Left:31); dry human coxal bones were evaluated. Photographs of samples for morphometric measurements were taken using a transparent osteometric box insert ignore into journalissuearticles values(TOB); designed for this study. Horizontal and vertical diameters of OF were measured according to two different principles. Measurements were taken to determine the localization of OF on the coxal bone insert ignore into journalissuearticles values(hip bone); relative to the acetabulum, pubis, and ischium. Shape analysis insert ignore into journalissuearticles values(visual typing); of OF was performed with the conventional method. In order to examine the shape variations of the OF in more detail, quantitative shape analysis based on Elliptic Fourier Analysis was performed with the SHAPE software. Results: A significant difference was observed between the diameter measurements obtained by the two methods insert ignore into journalissuearticles values(p<0,001);. Six visual types were determined in the qualitative shape analysis insert ignore into journalissuearticles values(oval, ellipsoid, piriform, trapezoidal, triangular, and atypical);. Researchers agreed on the shape types of 16 bones. Quantitative shape analysis revealed 77 principal components insert ignore into journalissuearticles values(PC);. The first nine significant PC explained the variation in the shape of OF cumulatively by 92,61%. Conclusion: The standard position, defined for the first time in this study, is recommended as an easy-to-reproduce position for dry bone measurements or radiological morphometric studies. The conventional shape analysis method insert ignore into journalissuearticles values(visual typing); is not capable of sufficient evidence-based discrimination. Therefore, examining the shape features of OF based on quantitative findings such as Elliptic Fourier Analysis may yield more accurate results.
