Abstrakt		Background. Degenerative processes in the hip such as coxarthrosis are an important problem in human population with high life expectancy. The results of clinical observations have indicated a hypothesis that the development of the degenerative processes in the hip is connected to a too high stress in the hip. This hypothesis has not yet been proved or disproved, mostly due to the fact that no acknowledged method for determination of the hip stress has been available to assess the contact hip joint stress on a larger population. Recently, the method HIPSTRESS, based on the mathematical modelling, was developed by which the contact hip stress distribution for a particular person can be determined from a standard anteroposterior rentgenograph of the pelvis and both proximal femurs. Applying this method and using rentgenographs from the archives enable retrospective study of the hip development over long-term follow up. The population with nonoperated hips is suitable for the study of the influence of the hip stress on the long term clinical outcome. Aim and hypothesis. The aim of this work was to contribute to the understanding of the reasons for coxarthrosis development - by verifying the validity of the hypothesis that the contact hip joint stress in early adulthood is connected to the clinical status of the hip in the older age. Methods. The hip stress was determined by an already acknowledged parameter - the peak stress on the hip weight bearing area. In addition, we introduced a new parameter - the index of stress gradient which describes how stress changes on the lateral edge of the acetabulum. Clinical status of the hip was determined by the Harris hip score. (Abstract truncated at 2000 characters).
