Mechanical considerations in impaction bone grafting.
In impaction grafting of contained bone defects after revision joint arthroplasty the graft behaves as a friable aggregate and its resistance to complex forces depends on grading, normal load and compaction. Bone mills in current use produce a distribution of particle sizes more uniform than is desirable for maximising resistance to shear stresses. We have performed experiments in vitro using m...
متن کاملImpaction grafting of the acetabulum with ceramic bone graft substitute
BACKGROUND AND PURPOSE Loss of bone stock remains a challenge in revision hip surgery. Grafting with allograft is well established, but there are problems with availability, cost, infection, antigenicity, reproducibility, and stability of the created construct. BoneSave is a biphasic porous ceramic consisting of sintered 80% tricalcium phosphate and 20% hydroxyapatite. In vitro and in vivo stud...
متن کاملRevision total hip arthroplasty with femoral impaction bone grafting.
PURPOSE To report the radiological and clinical results of revision total hip arthroplasty (THA) with femoral impaction bone grafting (IBG). METHODS 4 men and 9 women (15 hips) aged 38 to 84 years underwent revision THA with femoral IBG using Elite plus stems for aseptic loosening or infection. RESULTS The mean follow-up duration was 7.7 years. The Harris hip score improved from 61.7 to 83....
متن کاملImpaction bone-grafting in revision joint replacement surgery.
The standard graft material for impaction bone-grafting is fresh-frozen femoral head allograft morselized to a particle size as large as is practical to ensure stability and allow new bone formation. The graft must be sufficiently compacted to provide immediate mechanical stability; this requires containment of the graft and substantial impaction energy. Diaphyseal bone fracture and excessive i...
متن کاملImpaction grafting for acetabular revision: bringing back the bone.
Impaction grafting has been widely promoted on the acetabular side by Schreurs et al,1 with associated bone grafting and a cemented cup. The objectives of impaction grafting are to: 1) transform segmental defects into cavitary defects, 2) obtain a full compaction of the graft, 3) achieve primary stability of the cup, which is anatomically located in the acetabulum, and 4) restore bone stock. Th...
