Schematic drawings of the surgery design: (a) BMP group, (b) nonBMP group, and (c) control group. Blue circles, bone-substitute materials; dark-red line, CM soaked with rhBMP-2; green line, CM soaked with saline; BMP group, cylinder-type bone-substitute material covered by CM soaked with rhBMP-2; nonBMP group, cylinder-type bone-substitute material covered by CM soaked with saline; control group, no further treatment.
