title: A novel technique for femoral canal occlusion during cement pressurization in proximal femoral arthroplasty.
abstract: We describe a novel technique for occluding the femoral canal distal to the isthmus during proximal femoral arthroplasty. Synthetic bone models were reamed and sectioned to simulate loss of the proximal femur. Two experimental conditions were used. The first used no restrictor to act as a control. The second used calcium sulphate pellets impacted in distal femoral canal. A 100 × 12 mm Limb Preservation System stem (DePuy, Leeds, UK) was used in all experiments. We recorded cement pressure, leakage of cement, and penetration of cement into the femoral condyles. The calcium sulphate pellets prevented cement leakage, enabled higher cementing pressures, and prevented penetration of the cement into the femoral condyles. We would recommend this technique in cases where loss of proximal femoral bone loss requires the use of a cemented proximal femoral replacement.
