This guy seems to have had a medical condition, and it sucks for his patients and their families. And if what the news reported is true, he should've been stopped sooner. I also wonder if it was ignored as complications that happen; I've seen fractured femurs in THAs, but never anyone die from it. Could he get a criminal conviction like Dr. Death? I'm no where near being a lawyer. Dr. Death didn't have the physical brain pathology, but was narcissist, sociopath, what have you. This'll be interesting to watch though; I hadn't heard about it.
There was a neurosurgeon in my first job out of fellowship that I refused to work with because he had such a bad tremor I was afraid for his patients. I only did emergency cases with him, or if the schedule fell and I had to do spines with him, but another guy came in to help at that point and did most of the case. He was eventually forced to retire, and his wife put him in a nursing home (after I left). He was well loved by the hospital and community. He would occasionally ask me why I almost never worked with him.
