title: Asymmetric Bilateral Hip Dislocations: A Case Report and Historical Review of the Literature.
abstract: BACKGROUND
  Asymmetric bilateral hip dislocations are a rare injury pattern in which one hip dislocates posteriorly, and the contralateral hip dislocates anteriorly. We report a case of bilateral asymmetric hip dislocations and provide a comprehensive review of all available reports, identifying 104 total cases, which is 70 more than previously reported.
  
  
  OBJECTIVE
  To review and evaluate the total body of literature regarding bilateral asymmetric hip dislocations.
  
  
  METHODS
  Comprehensive literature review and analysis of all reports of bilateral asymmetric hip dislocations with concurrent case report.
  
  
  CONCLUSIONS
  Bilateral, asymmetric represent approximately 0.01%-0.02% of all joint dislocations. There has been a substantial increase in the number of case reports in the literature in the last 10 years. Males are more likely than females to incur this injury pattern and the most common mode of injury is motor vehicle accident Urgent closed reduction should be attempted in an efficient and safe manner to avoid potential complications, and open reduction should be considered in irreducible dislocations. Post reduction management should include stability assessment and CT to assess for associated injuries and intraarticular fragments; although no clear guidelines for post-reduction treatment emerged. Common complications include: nerve palsies, AVN and heterotopic ossification.
