Abstrakt		Increased contact hip-joint stress could be one of the reasons for the higher incidence of coxarthrosis in the female population. Therefore, in this work, the normalized peak contact stress in the articular surface of the hip joint was determined for 33 male and 113 female healthy hips. Stress was determined by the mathematical model describing one-legged stance, where hip geometry was taken into account for each individual. The hip geometry was determined from standard anteroposterior radiographs using the computer aided system. Our results show that the peak contact stress normalized with respect to the body weight is considerably higher (cca 20%) in the female population than in the male population. The difference is statistically significant (P < 0.00005) and is mainly attributed to the smaller radius of the articular surface in the female population. The results are in favor of the hypothesis that the increased hip joint contact stress in the female population could contribute to greater incidence of arthrosis in the female population relative to the male population.
