"I wouldn't say 2017 ended quite as planned. It's been a rough couple of days in ICU after a vehicle roll," Buchanan said in her caption.
"I just moved to a private room and everything is moving in a positive recovery direction."
She wished her followers a happy new year and said "off season just got a little more tough!!", in a post that has drawn thousands of comments.
