Severe osteolysis of the femur secondary to aseptic loosening in hip arthroplasty, remains a difficult revision scenario. Multiple techniques have been developed to aid the surgeon, including restoration of bone stock with impaction bone grafting or strut allografts, various distal fixation prostheses and mega-prostheses. Cemented femoral components, with integration of the cement into the cavitations, has largely fallen out of favour. We examined the long-term outcomes with this technique. Between 1977 and 1990, 109 patients had a cemented stem revision (without bone grafting) for severe femoral osteolysis in the absence of infection. Severe osteolysis was defined as cavitation in a minimum of 4 Gruen zones. Follow-up included functional scoring, radiological assessment and any complications. Further revision and survivorship analysis for stem failure or aseptic loosening of the femoral component were recorded.Introduction
