A mediolateral view of radiological image in FSB-BMC treated group. (M) Immediately post –operation, shows a radiolucent segmental defect area in mid shaft of radius bone (N) At 2nd week post –operation, shows a slight periosteal reaction at both ends of the segmental radius defect with slight radiopaque foci in the center of the defect (O) At 4th week post –operation, shows increased the periosteal reaction at both ends of the segmental radius defect with increased the opacity of the foci in the center of the defect (P) At 6th week post –operation, shows increased new bone growth and it extended in a straight direction from the proximal to the distal end of the bone defect. (Q) At 8th week post –operation, the segmental bone defect had been bridged by an increase in callus formation opacity. (R) At 12th week post –operation, shows a complete bridging of the segmental defect of radius bone by new bone formation.
