No fracture or dislocation. Incidental well defined ovoid foramen with corticated margins in the center of the thumb distal phalanx represents attempted bifid morphology.
Case Discussion
Bifid phalanx represents a congenital abnormality where two separate phalanges develop in one digit. In this case, complete bifid development has not occurred and a small mid-phalangeal foramen remains.
