title: Functional outcome after surgical treatment of perilunate injuries: A series of 12 cases.
abstract: OBJECTIVE
  Perilunate injuries (PLIS) are complex injuries, which are frequently missed in the initial setting, and delayed presentation leads to poor functional outcomes. In this study, we are presenting our experience of treating these injuries by surgical treatment and the effect of neglect on their outcome.
  
  
  METHODS
  In this retrospective study, 11 patients with 12 PLIS, which presented to our center from January 1, 2000 to December 31, 2012 were included. They were managed surgically as open reduction and internal fixation. Function was documented by using Mayo score. To ascertain the effect of the delay/neglect on the outcome, the patients were divided into two groups according to time between day of injury and final surgery (group I - operated within 6 weeks of injury and group II - treated after 6 weeks of injury).
  
  
  RESULTS
  Average postoperative Mayo score was 76.4. Average Mayo score in group I was 93.7 (90-95). Average Mayo score in group II was 67.1 (60-75). Although functional result as Mayo score was significantly better in group I (p value <0.5) even chronic or delayed group patients also had good to fair results.
  
  
  CONCLUSIONS
  Early diagnosis and treatment of such injuries should be emphasized as delay in treatment leads to progressive poor results. Well-planned surgical management gives good functional results even in delayed cases.
