Anatomy Question Re an Accessory Ulnar Wrist Ossicle

Add caption
This patient fell 1 week ago, known distal radial fracture, ordered by hand surgeon to evaluate possible "volar Barton fracture".  There is no fracture at the base of the thumb metacarpal.  My question is about the small, smooth ossicle adjacent to the base of the triquetrum.  This is 4.5 mm distal to the ulnar styloid.  Is this (A) traumatic displacement of an Os Triangulare...and, if so, what is it embedded in, what is torn?, or is this a (B) Os Hypotriquetrum (something listed in Wikipedia that I have never noticed)?
