Narrative:

All is calm and quiet; being an after-service and movie phase; passengers appear to be relaxing; doing computer work; or napping; usual activity. Flight attendants were gathering at the aft of aircraft by aft galley; catching up on how their service went; what food is left over; the usual cabin talk. We were taken off balance when the aircraft appeared to list to the left; I could hear the sound of the engines was at a louder level; I remember thinking; was that wind or engines. The flight attendants were leaning on each other trying to balance; as the aircraft seemed to rotate as if to return to center; but; before it reached that point; or the point where it seemed the flight attendants could get their footing the aircraft dropped sending me up hitting the ceiling; there was a smaller second drop after the first large one. I could also see some flight attendants were thrown into the aft galley; some ended up on the floor against the aircraft door. The flight attendant that was in front of me; who was also standing prior was thrown up into the ceiling and landed in the aisle. I thought I had dislocated my ankle; but it ended up being an ankle fracture. The head flight attendant called back to see if anyone was injured; as well as the captain calling to see our status. I however heard no PA given to the passengers; except to announce that we were going to divert to take the injured off; which included 3 flight attendants. I understood there were 7 passengers with minor injuries; and they opted to continue on to destination.my own feelings: the listing of the aircraft to the left; which sent us off balance; along with the sound the plane made was so strange. I wonder if wind is really what started the leaning. I also felt abandoned by the cockpit crew during the time; passengers were looking back at us the flight attendants for answers; and we had none to give them. [A company publication noted] 'recently there have been numerous turbulence events. Unfortunately; there have been 49 reported injuries year to date involving turbulence with 25 of those resulting in injuries serious enough that the flight attendants have lost time from work. '25 flight attendants year to date; that's an average of 5 flight attendants off each month since the year began. What's up with that? And that is just my company. Is there a change in our pilot's flying technique; or is there something really changing in our ecosystem; that is affecting planes; I hope the answer shows up soon.
