| Abstract: | [Objective]To study the biomechanics of weight-bearing area of avascular necrotic femoral head at different stages.[Methods]Biomechanical test on weight-bearing area was made for 57 moist femoral heads obtained in operation,which were divided into 4 groups: group of femoral neck fracture(group 1),group of pre-collapse(group 2),group of early collapse(group 3),group of advanced collapse(group 4).Six fresh moist human femur specimens were used as normal control.[Results]The descending order of the stiffness w... |
