Apparently this is just a very small os calcanei secundarium.Hilary sent this great reference:
#9 = os calcanei secundarium.

Does anyone know the name of this accessory ossicle?I can’t find it in Keats.
It’s certainly not an Os Supratalare.
(For now I’m calling it an Os Subtalare.)Not that it’s relevant, but this is a 48yoM with foot pain after falling 3 days earlier. CT showed tiny fractures on both sides of the Lisfranc Joint.
