The proximal interphalangeal joint of the right fifth finger is dislocated with the middle phalanx lying dorsal and medial to the proximal phalanx.
Case Discussion
Most dislocations of the interphalangeal joints are due to hyperextension. The proximal interphalangeal joints are the most commonly involved and in the vast majority of cases the dislocation is dorsal, as in this case.
