An Enroute Controller described an emergency descent made due to turbulence that involved some injuries on board the aircraft.

Narrative

Sector X called me after they put a PVD of a C560 up on my scope. They informed me that an aircraft was in severe turbulence; in a climb and was descending down to FL210. I approved this; the aircraft was on the boundary of my airspace and Sector Y. I put a PVD of the aircraft back up to Sector Y and was going to call but overheard the Sector X D-Side talking to that sector making arrangements. The Sector X D-Side passed the information to our Supervisor. When the C560 checked onto my frequency; I asked him the nature of the injuries that they reported to the Sector X. They informed me that there were head lacerations; but that the only assistance they required was direct to their destination. I cleared them direct and coordinated with the next Center. I also informed them of all the information and then shipped the aircraft to them. There is not much that could be prevented this event. Turbulence is turbulence. The only thing we could do was keep other aircraft away from this area after the incident occurred.
