title: [Revision hip arthroplastiy of the hip joint. Revision of the femur: which implant is indicated when?].
abstract: Cementless revision hip arthroplasty is described as state of the art, especially in cases of advanced bone loss of the femur. A requirement for a good result from cement-free revision hip arthroplasty is classification of the bone defect and the presence of a mechanically stable anchorage in the area of the original implant or, in cases of bone defects, distal to the original area in stable diaphyseal bone. The possibility of the accumulation of autografts or allogeneic osseous grafts and the entire removal of the cement and debris has been postulated. The advantages of cementless revision hip arthroplasty include regeneration of the bone stock and the often available modularity of the revision hip system, which allows adaptation to different bone configurations and also allows a partial change of the prosthesis in rerevision cases, such as in cases of sintering or derotation. Cemented revision arthroplasty should be done only in special cases, such as with marginal bone defects or for older patients with a short life expectancy.
