A bony fragment is detached from the middle finger middle phalanx base in the volar side.
Intraarticular extension of the fracture into the PIP joint is seen causing joint effusion and capsular distension.
Associated bone marrow edema/bruise also is seen 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 middle phalanx can occur.
