Biomechanical Evaluation for Bone Allograft in Treating the Femoral Head Necrosis: Thorough Debridement or not?

Fibular allograft with impaction bone grafting (FAIBG) is an effective hip-preserving method for avoiding total hip replacement in the early stage of femoral head necrosis (FHN). However, the question of whether thorough debridement should be used with FAIBG is controversial. This study first proposes employing computational biomechanical technology to explore the different mechanical performance of FAIBG with or without thorough debridement, which provides a biomechanical basis for choosing the proper treatment in clinic.
