RESULTS ① rhBMP2/BCB used alone was capable of healing the defect in large part by 16 wk, with a similar repair process and mechanism to that seen with RBX; ② use of rhBMP2/BCB in conjunction with vascularized periosteal graft exhibited stronger defect-repairing power, basically healing the defect by 8 wk. The repair process consisted of intramembranous and endochondral ossification that resembled the physiological repair during the fracture healing.
The repair process consisted of intrarnembranous and endochondral ossification that resembled the physiological repair during the fracture healing; Conclnsion Both methods are effective in repairing segmental bony defects, with NRBX used in conjunction with vascularized periosteal graft being preferred, considering the satisfactory osteogenesis, osteoeonduetion and osteoinduction seen with this method
