One hundred and twenty-one primary hybrid total hip replacements were performed in 107 patients. A titanium, porous-coated, hemispherical acetabular component was fixed with screws, and a collared, chromium-cobalt femoral stem, with a roughened surface and a thin layer of methylmethacrylate on the proximal third, was inserted with contemporary cementing techniques (that is, use of a femoral medullary plug, a cement gun, and centrifugation and pressurization of the cement). Fifteen patients (fifteen hips) died before a minimum duration of follow-up of seven years, four patients (four hips) were too ill for a detailed follow-up examination at the time of the study, and two patients (two hips) refused to be evaluated at the time of the latest follow-up. None of these twenty-one hips had had a revision or a reoperation at the time of the latest follow-up. Eighty-six patients (100 hips) were available for clinical follow-up at an average of 120 months (range, eighty-four to 153 months) and for radiographic follow-up at an average of 118 months (range, eighty-four to 153 months). The average age of the patients at the time of the index arthroplasty was sixty-five years (range, forty-five to eighty-seven years). Three acetabular components were revised because of dissociation of the liner in association with a fracture of a locking tine. One well fixed acetabular component was revised because of pelvic osteolysis, and the femoral stem in the same patient was revised because of aseptic loosening.
None of the ninety-six remaining acetabular components migrated, was classified as radiographically loose, or was revised because of aseptic loosening. Osteolytic lesions were identified adjacent to five acetabular components, and one of them was treated with bone-grafting around the well fixed acetabular shell. Two hips had a continuous radiolucent line at the interface between the acetabular implant and the bone.
Three femoral stems had evidence of radiographic debonding (a radiolucent line that was one millimeter wide or less between the cement and the prosthesis), and they were classified as radiographically loose despite excellent clinical results. Seven hips had osteolytic areas located in the proximal aspect of the most proximal zones of Gruen et al., and five had small osteolytic regions in more distal areas.
The Harris hip score for the eighty-two patients (ninety-six hips) who did not have a revision improved from 48 points (range, 22 to 70 points) preoperatively to 92 points (range, 53 to 100 points) at the most recent follow-up examination. Eighty-one patients had no, slight, or mild pain in the hip, and they were satisfied with the clinical result. In the present study, the hybrid total hip replacement with use of the Harris-Galante acetabular component and the Precoat femoral stem continued to provide an excellent result for most patients at an average of approximately ten years after the operation.
