We determined biomechanical parameters (magnitude of the resultant hip force, its inclination with respect to the vertical, contact hip stress, position of the stress pole, size of the load bearing area, functional angle of the load bearing area and stress gradient index) in a single patient before and after the periacetabular osteotomy. The operation was performed due to hip dysplasia. We used two mathematical models to determine the resultant hip force in the one legged stance: the HIPSTRESS model (1) and the one-muscle model (2). Stress was calculated by using the HIPSTRESS model for contact stress (2). The geometrical parameters needed for calculation of biomechanical parameters were assessed from standard anteroposterior radiograms taken from the archive. Before operation, both hips were dysplastic according to the HIPSTRESS method criterion. We found considerable improvement of the contact stress distribution in the operated hip, however, contact hip stress became less favorable in the contralateral hip after the operation. After the operation, the operated hip became normal while at the contralateral side, the degree of the dysplasia has increased.
