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 کاملSubsidence of the stem after impaction bone grafting for revision hip replacement using irradiated bone.
Loss of bone stock is a major problem in revision surgery of the hip. Impaction bone grafting of the femur is frequently used when dealing with deficient bone stock. In this retrospective study a consecutive series of 68 patients (69 hips) who had revision of a hip replacement with femoral impaction grafting were reviewed. Irradiated bone allograft was used in all hips. Radiological measurement...
متن کاملImpaction bone grafting: a laboratory comparison of two methods.
In revision total hip replacement, bone loss can be managed by impacting porous bone chips. In order to guarantee sufficient mechanical strength, the bone chips have to be compacted. The aim of this study was to determine in an in vitro simulation whether the use of a pneumatic hammer leads to higher primary stability than manual impaction. Bone mass characteristics were measured by force and d...
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...
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...
