This is a PA ulnar deviation x-ray of my left wrist from last month, which gives a good view of the scaphoid bone from above.
The bone is chipped in the area pointed by the arrow, due to a fall that occurred 20 or so years ago. Somewhere in there, there’s also a tiny detached fragment of cartilage that calcified (as seen in a CT scan at the time). I was lucky, because typically the result of a fall with outstretched hand for people aged 17-40 is the scaphoid fracture, which are known to have unpredictable healing. Lately, however, due to a tendonitis, the fragment too is acting out. I’m left handed so this is causing some trouble, and that’s why the recent x-rays.
