Evaluation of biomechanical status of dysplastic human hips

The evaluation of the biomechanical status of human hip joint was performed . Required parameters were assessed from standard antero-posterior rentgeno graphs and the value of contact stress on the weight bearing area is calcul ated. We analysed 45 dysplastic human hips and compared measured values to 81 healthy hips. The peak contact stress on the weight bearing area is cons iderably and statistically significantly higher in dysplastic hips compared to healthy hips. The Wiberg centre-edge angle is statistically significant ly smaller in group of dysplastic hips compared to healthy hips.
