Abstract
Aim: The purpose of this study was to assess the results with use of a newly developed, conical, titanium, ribbed shaft socket designed for cementless pressþt into the dorsocranial ilium for revision total hip arthroplasty Methods: 25 hips had an acetabular revision with a pedestal cup (Centerpulse). All of the patients had a type III defect according the AAOS classiþcation. There was an average follow-up of 4.3 years, with a range of 3 to 5 years. One patient died during the study period. All patients were evaluated radiographically, by CT-Scan and clinically. Results: At the time of follow-up, 22 (91.7%) of 24cups were stable. Both loosenings affected patients with an low-grade infect. In this group none aseptical loosening occurred. The average Harris Hip Score improved from 41 points (range: 16–78 points) preoperatively to 84 points (range 56–98 points) postoperatively. Complications included four dislocations without recurrency. The radiological follow-up examinations revealed osteointegration of 21 implants. Conclusion: The presented þndings show the short-term efþcancy of the prcedure with respect to implant þxation and clinical results in large acetabular defects, but longer follow-ups and a larger number of patients are needed before the durability of this reconstructive technique can be assessed. Our results should be considered encouraging.
