N2 - The transfemoral approach in its traditional form, using a nonmodular Wagner self-locking revision stem, has the disadvantages of a less predictable union rate of the bony flap and a high rate of stem subsidence. To investigate whether this situation can be improved by using a modified transfemoral approach and modular curved cementless revision stems, we prospectively analyzed 68 hip revisions and followed them clinically and radiographically for a minimum of 24 months (mean +/- standard deviation, 32.4 +/- 11.2 months). One year after the operation, the osteotomy showed bony consolidation in all but one case (98.5%). We noted subsidence in six cases (8.8%) and two of these stems became loose. In all of these cases, the circular fixation zone of the stem in the isthmus of the femur was less than 3 cm. The Harris hip score improved continuously from 41.4 +/- 14.5 points preoperatively to 85.9 +/- 14.6 points 24 months postoperatively. The modified transfemoral approach in combination with a curved, modular revision stem showed reproducibly good results concerning union of the bony flap and subsidence of the stem if the fixation zone was not less than 3 cm.
