Biarticular total femoral spacer for complete bone loss in periprosthetic joint infection. A technical modification

The management of complete bone defects in hip and knee periprosthetic infection is still a real surgical challenge. We present a technical modification for performing a biarticular total femoral spacer with a femoral nail without the need to approach the proximal tibia. Three patients were operated with this technique. There was no intraoperative complication. The infection was resolved in all patients operated at final follow-up. All patients improved their previous functional situation and could walk with different aids. This technical modification is an alternative for cases where it is necessary to resect the complete femur, but it is not necessary to approach the tibia.
