Methods: Forty nine cases of cementless hip replacement were followed up for average 3.5 years, 42 of whom had X ray films on preoperation or operation day. Results: Harris scores and patients satisfaction were low but pain was significant and prolonged when cortical indices were low. Conclusions: CI is a reliable semi quantity parameter for clinical evaluation of femoral quality. Osteoporosis patients predispose to thigh pain. Lag for full weight loading and avoidance for torsion motion can contribute to less pain when CI≤ 2.2 .展开更多
