The fact that I have an os trigonum and you don't!

To be clear, I don't actually like having an os trigonum, I don't really have an opinion of it, but I am ahead of myself. I thought of this last night when discussing running and injuries with a few of my cohorts at the watering hole.


Last summer I was having problems with my ankles and I had to take my mother to the orthopedist (she had snapped one of her ankles in two places whilst falling down the stairs, it's a long story but she is fine now), so I thought that I would have them check me out. After I described my symptoms to the orthopedist he said that I probably had tendinitis in my ankles or I was one of 10% of the population that had an accessory bone called the os trigonum and somehow I had aggravated this bone with my exercise regemine. To be certain, he took an x-ray and lo and behold- I had the extra bone! To this day we are not sure whether the tendin or the bone were causing me grief (that would have taken an mri), but I do know that I have an os trigonum and you probably don't.
