title: CASE REPORT Bilateral Paradoxically Symptomatic Luno-triquetral Coalition: A Case Report.
abstract: OBJECTIVE
  While bony luno-triquetral coalitions are known to be asymptomatic, fibro-cartilage unions can cause ulnar-sided wrist pain. The purpose of this case report is to present a paradox clinical constellation of bilateral luno-triquetral coalition. Furthermore, recommendations for proper diagnosis and treatment options will be discussed.
  
  
  METHODS
  The case of a 21-year-old female patient is reported, where a bony coalition of one side caused wrist pain and the contralateral fibro-cartilage bonding was asymptomatic.
  
  
  RESULTS
  Because of the stable bony coalition in the symptomatic wrist, we refused to undertake a luno-triquetral fusion and continued conservative treatment with the option of wrist denervation.
  
  
  CONCLUSIONS
  Consequently, not only incomplete but also complete luno-triquetral coalitions can cause wrist pain. Unfortunately, no clear biomechanical explanation is available for this finding.
