Weather
Our flight departed late due to the aircraft arriving late from the previous station. During the flight we told the F/A's to remain seated on climb out until they heard from us. Upon reaching cruise altitude FL380; and talking to ATC about the current turbulence; we told the F/A's that they could get up with the smooth/occasional light chop. This flight condition stayed for most of the flight and we sat the Flight Attendants down twice as precaution when we heard reports of greater than occasional light chop; or visually saw what looked like clouds with possible bumps along our route. At the time of the incident we had started our descent out of FL380; and leveled at FL360. The seatbelt sign was on and the F/A's were up with only occasional light chop. After leveling at FL360; the aircraft hit what felt like a light wake turbulence and after a few minutes the F/A's called and said one of the FA's had a broken ankle and was being treated by a Doctor and Vet. At this point I was assigned the First Officer to take the ATC communication and the flight controls. I coordinated with the F/A's; Operations and Dispatch for our arrival for medical staff to meet the aircraft. Upon arrival; we kept the Passengers seated while medical personnel boarded the aircraft and took command of the injured F/A. [Medical assistance on radio] was not contacted because the injured Flight Attendant was stable and secured in a seat and because of reported light to moderate turbulence in the area; I wanted to keep all Crew Members safe.
