AB Phalangeal  dislocations  are  common,  generally  dislocate  dorsally,  are  caused  by  hyperextension  and  axial  compression,  and  may  have  associated  volar  plate  damage.  PIP  volar  dislocations  can  be  irreducible  secondary  to  rupture  of  the  extensor  tendon  and  herniation  of  the  proximal  phalanx  through  the  extensor  hood,  requiring  operative  repair.  MCP  joint  dorsal  dislocations  are  often  due  to  hyperextension.  DIP  dislocations  are  the  rarest  but  can  occur  when  an  axial  force  is  applied  to  the  distal  phalanx.  Gross  deformity  is  noted  on  examination,  with  the  distal  phalanx  generally  displaced  dorsally.
