It's likely that the bump causes some damage to the memory card or camera reader. You may take out memory card and then connect memory card to computer with a card reader. This will make it work if camera got problem reading the memory card. You may read wiki below if you do not know much about memory card reader

You can get a memory card reader from ebay or amazon if you dont have one. It should be quite cheap, around $2.

If still have problem, you may check whether memory card shows as a drive letter in computer. If not, you can go to device manager and then assign a drive letter to the memory card. see this guide

After you can see the memory card on computer as a drive letter, try to open it. If still have problem, follow this guide

If you have to format the memory card, please remember to check "Quick format" option. Also, do not use the memory card before you get back all your pics.

After you restored all your files, you can then do a low level format and see whether you are able to use it in camera.
