Pope Francis has fallen over and injured his right arm but did not suffer any fractures, the Vatican says.In a statement, the Holy See press office said that due to a fall Thursday morning in the Casa Santa Marta, the popes residence, the 88-year-old pontiff suffered a contusion to his right forearm, without fracture.The statement added that his arm has been immobilized as a precautionary measure.Official pictures showed the pope wearing a cloth sling as he held meetings.The pope has suffered a number of health problems in recent years and this is the second fall he has had in a matter of weeks. In early December, he appeared with a large bruise on his chin after falling and hitting his bedside table during the night.Since 2022, the pope has made use of a wheelchair due to mobility problems caused by pain in his knee. In his recently published autobiography Hope, Francis said that he is in good health and ruled out resigning from his position, but said that the reality is, quite simply, that I am old.He said it was embarrassing at first to have to use a wheelchair, but old age never arrives by itself, and it must be accepted for what it is.He added: the Church is governed using the head and the heart, not the legs. I do physiotherapy twice a week, I use a walking stick, do as many steps as I can, and I carry on.
