We know that a fifth to a third of patients with cementless THA complain of thigh pain. In order to obtain an initial fixation, to prevent loosening of the stem and consequently to protect against thigh pain, we used a very small quantity of cement at the distal end of the stem. We report our results in twelve female patients with osteoarthritic hips operated on with the cementless THA. Our method was as follows: just before putting the stem into the femoral bone we inserted a minute quantity of cement, the average weight of which was 0.85g, into her pulp chamber, and then we set up the stem. Post operative rehabilitation was practiced the same as for cementless THA. The result was that thigh pain appeared in only one patient (5.9%), and in their X-rays after surgery we found five hips with a radio lucent line at Zone 1, but except for one case the width was below 1mm. We report our experiment study and believe that our method is effective for preventing thigh pain after cementless THA.
