A bony fragment detached from the middle finger middle phalanx base in the volar side
Intraarticular extension of the fracture into the PIP joint causing joint effusion and capsular distension
Associated bone marrow edema/bruise also at the site of fracture.
Case Discussion
Hyperextension injury involving the PIP of the finger can avulse the volar plate which is commonly associated with a volar avulsion fracture at the base of the middle phalanx.
When the volar avulsion fracture involves a significant portion of the articular surface, instability and dorsal dislocation of the middle phalanx can occur.
