Intraarticular fractures involve the volar aspects of the distal phalangeal bases of the third and fourth digits (middle/long and ring fingers). The fragments appear corticated, indicating subacute to chronic age. Both fragments are proximally displaced. The fracture of the third digit involves half of the articular surface for the distal interphalangeal joint.
There is a permeative appearance to the bone of the third and fourth digits that most likely represents regional osteopenia/hyperemia secondary to the fractures.
Ossific fragment distal to the ulnar styloid represents an old avulsion fracture versus ossification of the triangular fibrocartilage complex. Degenerative changes are scattered along the interphalangeal joints and first carpometacarpal joint.
