title: A case report of distal radioulnar joint dislocation fixed by using mini-plate-button.
abstract: BACKGROUND
  Pathological factors may cause significant distal radioulnar joint (DRUJ) dislocation, which is a rare clinical entity in orthopedic literature, and corresponding treatments are not uniform.
  
  
  METHODS
  We describe the case of a DRUJ dislocation caused by giant cell tumour of tendon sheath (GCTTS) in wrist. At surgery, the stabilization of DRUJ was constructed by using mini-plate-button after removal of intraoperative removal of the tumor. Postoperative plain films showed good position, and no obvious dislocation was found.
  
  
  CONCLUSIONS
  Reduction of DRUJ dislocation was facilitated by mini-plate-button and absorbable suture. The treatment avoided intro-articular or extra-articular ligament construction and damage of adjacent tissue and bone.
  
  
  CONCLUSIONS
  For DRUJ dislocation caused by GCTTS leading to severe tendon and ligament damage, the operative treatment of mini-plate-button may be effective.
