Simultaneous dorsal dislocation of interphalangeal joints in a finger.
Simultaneous proximal and distal interphalangeal joint dislocations in a single finger are rare. Even though the joints above and below are routinely evaluated, one of the joint dislocations can be missed. When phalangeal dislocations are suspected, special attention should be given to obtaining sufficient roentgenographic views both before and after reduction. The joints should be thoroughly examined in an attempt to distinguish capsular contraction from soft-tissue interposition. Failure to recognize initial simultaneous dislocations may result in capsular contraction and require surgical intervention.
