عنوان انگلیسی Cemented liner in cementless cup
چکیده انگلیسی مقاله Backgrounds In some situations, an orthopedic surgeon may be forced to use unusual combinations of liners and metal shells. For example, in revision total hip surgery, for  retaining  of  well fixed cementless cup14,15  with  locking mechanism which can not be re used ,a cemented liner can be used in the metal shell   Methods In this study we report ten years follow up of these cases. Fourteen of 82 cases (16.5%) of revision total hip arthroplasties  had cemented polyethylene liner in cementless metal shell. Average follow up was 6,2 years( 1 to 10 years). Their age and sex , cause of revision, follow up time, Harris hip score , loosening ,constrained liner, osteolysis ,dislocation, dislodgement of cemented liner from cementless cup, Leg length discrepancy, cause of using this combination, infection, and use of allograft behind shell for osteolysis around cup were considered. Results The most common cause of revision was osteolysis (64%). The most common cause of using this combination was impaired locking mechanism (65%). There were few complications (one osteolysis and one infection). In five cases (36%) constrained liners were used and in ten cases (72%) allograft was needed. The final Harris Hip scores were mostly good or excellent (78%). Only one dislocation was seen. Conclusions It seems that if it is necessary to use this non ordinary combination of cemented cup in cementless shell, there are no significant problems and complications.
