I'm so sorry - such a terrible accident ( and more scary stories along the way ). I'm afraid of something like that happening to me since I've got diagnosed as having osteoporosis versus osteopenia before ( went on weekly medications with a hope of slowing the process down ).
My mom got her wrist, hip and such broken a few times - long and slow recovery each time. Take your time to heal, don't rush things, go with doctor advice ( and hug your lovely kitty ).
