Abstract
Introduction: In some special situations during the revision total hip arthroplasty with well fixed, well oriented acetabular cementless cup, orthopedic surgeons may prefer to retain the well-fixed cementless cup. The aim of this study was to report the follow-up of some cases treated with such a technique during a 10-year period.
Methods: During 2004-2014, all cases of revision total hip surgery performed in Sina Hospital, Tehran, Iran were evaluated. 14 of 82 cases (16.5%) had cemented polyethylene liner in cementless metal shell. The demographic data, reasons for use of such revision technique result was evaluated by Harris Hip Score.
Results: The most common reason was osteolysis (64%), and the most common cause was impaired locking mechanism (65%). There were few complications (one osteolysis and one infection). In five cases (36%) constrained liner was added and in 10 cases (72%) allograft was needed. The final Harris Hip Scores was good or excellent in 78%. Only one dislocation was seen.
Conclusion: Cemented cup in cementless shell can be used in revision hip arthroplasty in well-fixed Acetabular shell situations with acceptable outcom.
