Autogenous bone grafts have long been considered the“gold standard”and most effective material in bone regeneration procedures.[1]Autogenous bone grafts are used to repair bone defects caused by nonunion,infection,tumor resection,and spinal and joint fusion.[2]It has been reported that more than 200,000 autologous bone grafts are performed in the United States each year.[3]Although there are no specific statistics on the annual number of bone grafts performed in China,autologous bone grafting is the most common surgical technique in *** iliac crest remains the most common donor site,along with the fibula,ribs,tibial metaphysis,proximal humerus,distal radius,and greater trochanter.[4,5]Various bone-graft options provide different amounts and qualities of cortical,cancellous,and corticocancellous bone.[6,7]Autogenous bone graft is osteogenic,histocompatible,provides structural support.
