Mechanical characteristics of the bone-graft-cement interface after impaction allografting.
Impaction allografting is an attractive procedure for the treatment of failed total hip replacements. The graft-cement-host bone interface after impaction allografting has not been characterized, although it is a potential site of subsidence for this type of revision total hip reconstruction. In six human cadaveric femurs, the cancellous bone was removed proximally and local diaphyseal lytic de...
متن کاملRevision of the femoral prosthesis with impaction allografting.
Impaction allografting is the only technique, to date, that has been shown to reverse the loss of bone stock encountered during revision hip arthroplasty. However, early stem subsidence, dislocations and a high occurrence of periprosthetic fractures are well documented with this method. This article reviews the biomechanical and biological characteristics of compacted morsellised graft, on the ...
متن کاملImpaction femoral allografting and cemented revision for periprosthetic femoral fractures.
We reviewed retrospectively the outcome of the treatment by impaction grafting of periprosthetic femoral fractures around loose stems in 106 patients with Vancouver type-B2 and type-B3 fractures. Eighty-nine patients had a cemented revision with impaction grafting and a long or short stem. The remaining 17 had cemented revision without impaction grafting. Fractures treated by impaction grafting...
متن کاملCement penetration and primary stability of the femoral component after impaction allografting. A biomechanical study in the cadaveric femur.
This study explored the relationship between the initial stability of the femoral component and penetration of cement into the graft bed following impaction allografting. Impaction allografting was carried out in human cadaveric femurs. In one group the cement was pressurised conventionally but in the other it was not pressurised. Migration and micromotion of the implant were measured under sim...
متن کاملThe cement mantle in femoral impaction allografting. A comparison of three systems from four centres.
An analysis of the cement mantle obtained with the Exeter impaction allografting system at one centre showed that it was either deficient or absent in almost 47% of Gruen zones. We therefore examined the mantle obtained using this system at another hospital and compared the results with those from the CPT and Harris Precoat Systems at other centres. The surgical indications for the procedure an...
