Proximale Verankerung von Hüft-Endoprothesen mit poröser Oberfläche: 6-Jahres-Ergebnisse

PROBLEM The anatomically shaped pcl (ESKA) total hip replacement has a porous coating of the proximal stem and the cup to allow for bony ingrowth. The tip of the stem is polished. METHOD We report the results of 96 THR 6.2 years (5.25-6.7) after implantation. RESULTS There were no revisions during this period. One stem showed radiographic loosening at follow-up. There was stress-shielding in 9.4% in contrast to the concept of proximal fixation. Thigh-pain was found in 9.4%. One patient demonstrated disabling thigh-pain despite radiologic bony ingrowth. By drilling the femur distal to the tip of the stem a remarkable relief was achieved. CONCLUSION Despite numerous cases of stress-shielding …
