Cracked MacBook touch pad
MacBook Pro
Open the MBP bottom case cover and the odds are that the battery has expanded and damaged the trackpad. The battery must removed immediately if that is the case. Take the MBP to a genius bar and see if it can be repaired.
Ciao.
I'm with Oglethorpe on this one, the battery has swollen, remove it before more damage is done and take the Mac to an Apple Store.
