Narrative:

Prior to descent, we received an ACARS message of a B747 experiencing severe turbulence approaching anc from the west. We briefed flight attendants to clean up early for turbulence on approach. I made an announcement to the passenger about early clean-up and possible turbulence on approach. I requested a rerte to north of anc over knik arm. WX reports and experience indicated a better ride over knik than approaching from south over turnigan arm. We were observing rolling clouds approaching on descent. The captain made an announcement 'flight attendants, if you're not already seated, take a seat now.' the descent had been uneventful until that announcement at 13000 ft. At 11000 ft, we were hit by moderate turbulence as we entered a left turn. We used full control deflection to maintain controled flight. The turbulence subsided by about 7000 ft. After landing, we got a call for ambulance assistance for one of the flight attendants in the back. She had hit the ceiling, then broke her ankle in 3 places. A non revenue flight attendant laid on the floor with her while a second non revenue flight attendant and jump seating pilot held them down from their seated position in the last passenger row. We learned from our crew debrief that the injured flight attendant called for help from the non revenue flight attendant, directing the other working flight attendant seated to stay in her jump seat. Her intent was to avoid injury to the remaining flight attendants to keep her safe and available to perform her duties as needed. Good head prevailed upon her part. She'll be 3 months recovering, but looks forward to coming back to work. She was interviewed by the NTSB. The captain and myself made a written report to the NTSB. Crew debrief was very helpful for everyone involved.
