Tips and tricks for femoral Fassier-Duval rod revision in osteogenesis imperfecta

Purpose

Osteogenesis Imperfecta (OI) is characterized by severe bone fragility, requiring intramedullary telescopic rodding such as the Fassier-Duval (FD) rod to correct and prevent progressive deformities. Although the FD rod is widely used, the revision rates, especially in the femur, remain high. This study aims to evaluate a structured decision-making framework and detailed surgical techniques for FD femoral revision in OI.
