Research progress of induced membrane technique in the treatment of lower limb bone defect
Bone defect refers to the loss of bone structure caused by bone infections,bone tumors,congenital diseases,or severe trauma.Due to the increased incidence of high-energy injuries and the characteristics of anatomical structure,lower limb bone defects are particularly common and become the research difficulties in the field of traumatic orthopedics.Traditional treatment options include vascularized fibular grafting,open bone grafting,and bone transport technique,but these techniques have inherent limitations.In recent years,induced membrane technique has gradually been used for the reconstruction of segmental bone defects due to its standardized,simple and efficient operation procedures.Induced membrane technique consists two stages:the first stage is to generate an induced membrane with biological effects,the second stage is to fill the defect area with bone fillers(autologous bone,allogeneic bone,artificial bone or bioactive substances,etc.),then the filled bone graft material is fixed to the existing bone structure by specific fixation methods.In this paper,the basic research of induced membrane technique and the related research progress in the treatment of lower limb bone defect at home and abroad are reviewed,aiming to discuss its potential development direction for basis and clinic.
