Let's look at definition of personality disorder.
"The deviation must manifest itself pervasively as behaviour that is inflexible, maladaptive, or otherwise dysfunctional across a broad range of personal and social situations (i.e., not being limited to one specific "triggering" stimulus or situation). There is personal distress, or adverse impact on the social environment, or both...."
So not traits, but actual disorder. Again, I wonder how it could be that you can manage being a surgeon. How could a personality disorder actually fit here in this very intellectually and physically demanding occupation, where high self discipline, emotional intelligence, reliability, leadership skills, teamwork, etc, are a must. I don't think you can "mask" the symptoms or adapt because if you could, you would not have a personality disorder in the first place. These people can't adapt. So the only one that comes even close is, like you mentioned, "compulsivity" and I suppose that is helpful if you're just following a manual or assisting the main surgeon but what you're the main guy, the team leader. Don't you need to be flexible, rely on your judgment, etc? In fact, that is the main difference between the responsibility of people in lower positions and higher ones, the room for decision making and reliance on personal judgment as opposed to following the rules. A guy in admin position in government, yes, but imagine having a president who meets the full criteria for OCPD.
