title: Traumatic mechanisms and therapeutic results of the perilunate injuries.
abstract: OBJECTIVE
  In this study, eighteen patients who have had perilunate injury with dislocation or fracture, were evaluated and the patho-mechanics and surgical treatment were studied.
  
  
  METHODS
  According to the Green and O'Brien's classification, type 1 injury occurred in one patient, type 2 in nine, type 4A in five, type 4C in one and type 4D in one. The other one case could not be classified using the Green and O'Brien's criteria.
  
  
  RESULTS
  According to the Evans scoring system, good results were achieved in thirteen patients, fair results, in four, poor results in one and very poor results in none. When the patho-mechanics was estimated based on the Mayfield's criteria, seventeen patients were classified as stage 3. However only one case was extremely unusual and should be classified as a subtype of stage 2.
  
  
  CONCLUSIONS
  The results were good in the majority of patients who had repair of perilunate injury.
