Narrative:

During cruise, we received an ACARS message from dispatch stating that during our pushback at ord, we had overturned a cart and caused minor injuries. The captain and I were very surprised to read this message. After reviewing the dispatchers comments, we realized what could have happened. Upon receiving pushback clearance, we were instructed to push 'tail south' for a north taxi out of the gate. This was the first time the captain, or myself, taxied north out of the gates. After salute and release from guidance, we were instructed by ramp control to transition to the line and follow an A320 which was abeam us and last in line. The captain started to move, but realized that he needed to wait for the line, and the A320 to move in order to follow him because of the angle we had. He felt uncomfortable blocking. After the line moved, the captain proceeded to taxi, and because of the turn he had to do, it took a while for our airplane to move after power application. I don't believe any excessive power was used, but I was looking out the window for traffic and did not see the N1 gauges.

Title: B767 CREW WAS ADVISED THEY CAUSED BLAST DAMAGE AND PERSONAL INJURY ON TAXI OUT IN ORD.

Narrative: DURING CRUISE, WE RECEIVED AN ACARS MESSAGE FROM DISPATCH STATING THAT DURING OUR PUSHBACK AT ORD, WE HAD OVERTURNED A CART AND CAUSED MINOR INJURIES. THE CAPT AND I WERE VERY SURPRISED TO READ THIS MESSAGE. AFTER REVIEWING THE DISPATCHERS COMMENTS, WE REALIZED WHAT COULD HAVE HAPPENED. UPON RECEIVING PUSHBACK CLRNC, WE WERE INSTRUCTED TO PUSH 'TAIL S' FOR A N TAXI OUT OF THE GATE. THIS WAS THE FIRST TIME THE CAPT, OR MYSELF, TAXIED N OUT OF THE GATES. AFTER SALUTE AND RELEASE FROM GUIDANCE, WE WERE INSTRUCTED BY RAMP CTL TO TRANSITION TO THE LINE AND FOLLOW AN A320 WHICH WAS ABEAM US AND LAST IN LINE. THE CAPT STARTED TO MOVE, BUT REALIZED THAT HE NEEDED TO WAIT FOR THE LINE, AND THE A320 TO MOVE IN ORDER TO FOLLOW HIM BECAUSE OF THE ANGLE WE HAD. HE FELT UNCOMFORTABLE BLOCKING. AFTER THE LINE MOVED, THE CAPT PROCEEDED TO TAXI, AND BECAUSE OF THE TURN HE HAD TO DO, IT TOOK A WHILE FOR OUR AIRPLANE TO MOVE AFTER PWR APPLICATION. I DON'T BELIEVE ANY EXCESSIVE PWR WAS USED, BUT I WAS LOOKING OUT THE WINDOW FOR TFC AND DID NOT SEE THE N1 GAUGES.
