Hip stress distribution may be a risk factor for avascular necrosis of femoral head
Original language description
Avascular necrosis of femoral head (AN) is a hip disorder with various risk factors, however, the underlying mechanisms are not yet understood. In order to elucidate the effect of the mechanical factors on AN we have compared a group of hips at risk forAN and a group of healthy hips with respect to biomechanical parameters: functional angle of the weight bearing area (?F), position of the stress pole (?), index of the gradient of the contact stress at the lateral border of the load bearing area (Gp) and peak contact hip stress (pmax). The test group representing hips at risk for AN consisted of 32 male hips contralateral to the necrotic hips while the control group consisted of 46 healthy male hips. The biomechanical parameters we computed with the HIPSTRESS method (based on measurements of geometrical parameters from standard anterior-posterior pelvic radiographs).
