Biarticular total femoral spacer for complete bone loss in periprosthetic joint infection. A technical modification. / Espaciador femoral total biarticulado para el tratamiento de la infección periprotésica de cadera y rodilla con pérdida completa de hueso. Modificación técnica.

BACKGROUND: The management of complete bone defects in hip and knee periprosthetic infection is still a real surgical challenge. MATERIAL AND METHODS: We present a technical modification for performing a biarticular total femoral spacer with a femoral nail without the need to approach the proximal tibia. RESULTS: 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. CONCLUSIONS: 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.
