The kidney on the right side lies slightly lower because the liver pushes it down. So the border is sort of rib #11.5 or 12th between the liver and the right kidney.
On the left side, the border between the spleen and the left kidney is the 11th rib --> 9th and 10th are above this so the injury was to the spleen. Also recall that the MOST commonly damaged organ after trauma is the spleen.
