Nutrient foramen that was mistaken for a 4th proximal phalanx fracture

Nutrient vascular foramen within the right 4th proximal phalanx simulating a fracture (red arrows). Nutrient foramina within the 2nd and 5th proximal phalanges are also subtly visible (yellow arrows).
Case Discussion
The phalanges typically possess a single foramen however the proximal phalanges of the fingers commonly have two, with all foramina directed away from the origin of bone growth.
