My mother leans to the left while sitting in her chair. Recently, she had a nasty fall and fractured her humerus. Since, the fall she hasn't been able to stand or sit up. I was wondering if this is coming from her dementia or if the hospital missed something. By the way, initially, she was told she wouldn't need surgery for the fracture and unfortunately, four weeks later she just endured trauma surgery to re[pair the fractured and no weight on this injury for two months. We are so concerned about our mother who is 86.
