Elizabeth Taylor, seeking to quell speculation about her health, says she broke her back last summer and is being treated for the injury. The film star, plagued by alcohol and drug dependency in the past, said in a statement that she entered the Betty Ford Clinic in Palm Springs, Calif., during a difficult recovery period. "There's been significant speculation about my health," Taylor said. "The truth is that last summer I fractured my back - a compression fracture of the first lumbar vertebra." She said while recovering, she entered the famed substance abuse clinic "for a brief period. I am fine now!" Rumors were renewed by the announcement Tuesday that Taylor's California doctors were under investigation based on records showing she received prescriptions for large amounts of opiates, barbituates and stimulants.
