## Abstract Bone loss in the proximal femur at the time of revision hip arthroplasty for a failed primary cemented femoral component can substantially reduce the stability of the revision stem, Use of an extended‐length femoral component has been suggested to aid in achieving long‐term fixation; ho
The occlusion and stability of five synthetic plugs used to restrict the femoral canal prior to cemented arthroplasty was assessed. A model was employed consisting of a hollow wooden dowel to simulate the canal, with adapters fixed to both ends to accommodate cement insertion and pressurization, and
## Abstract A combination of laboratory experiment and computational simulation was performed to assess the role of interface porosity on stem migration. The early motion of in vitro prepared cemented femoral components was measured during application of cyclic stair climbing loads. Following testi
