A mediolateral view of radiological image in FSB treated group. (G) Immediately post –operation, shows a radiolucent segmental defect area in the mid shaft of radius bone. (H) At 2nd week post –operation, shows a little periosteal response at both ends of the radius bone defect. (I) At 4th week post –operation, there was an increase in the periosteal reaction, and a radiopaque foci of newly formed bone is visible in the defect’s center. (J) At 6th week post –operation, the radius defect’s new bone growth was increased and extended from both ends. (K) At 8th week post –operation. there was an increase in newly formed bone and extended from both ends of the radius defect towards the central new bone formation foci. (L) At 12th week post –operation, shows increased the opacity of new bone formation and extended in a straight direction from both ends of the radius defect towards the central new bone formation foci, with partially bridging the radius defect.
