AB Neurogenic  arthropathy  is  joint  destruction  resulting  from  loss  or  diminution  of  proprioception,  pain,  and  temperature  perception.  Although  initially  described  in  the  knees  of  patients  with  tabes  dorsalis,  it  is  more  frequently  seen  in  association  with  diabetic  neuropathy  (foot  and  ankle)  or  syringomyelia  (shoulder).  As  normal  muscle  tone  and  protective  reflexes  are  lost,  secondary  degenerative  joint  disease  ensues,  resulting  in  an  enlarged,  boggy,  relatively  painless  joint  with  extensive  cartilage  erosion,  osteophyte  formation,  and  multiple  loose  joint  bodies.  Radiographs  can  reveal  striking  osteolysis  that  mimics  osteomyelitis  or  dramatic  destruction  of  the  joint  with  subluxation,  fragmentation  of  bone,  and  bony  sclerosis.
