[Cement-free diaphyseal fixation principle for hip shaft exchange in large bone defects--analysis of 12 years experience with the Wagner revision shaft].
Considering the increasing incidence of revision for failed total hip arthroplasty, we evaluated if the principle of uncemented diaphyseal fixation which is realised with the Wagner SL revision stem, can solve the technical problems of significant bone loss of the proximal femur and can offer good preconditions for bony restoration in the medium term. ⋯ Due to the encouraging results with the Wagner revision stem, the principle of uncemented diaphyseal fixation seems to us to be able to solve most of the technical problems in cases of significant bone loss and obviously offers good preconditions for bony restoration. Our own classification system was effective and useful for preoperative planning.
