title: Arthroscopic study of injuries in articular fractures of distal radius extremity.
abstract: OBJECTIVE
  To analyze the incidence of wrist ligament and cartilage associated fractures of the distal radius, through arthroscopy, correlating with AO/ASIF classification.
  
  
  METHODS
  Thirty patients aged between 20 and 50 years old, with closed fracture from groups B and C according to AO/ASIF classification were selected. All of them were submitted to wrist arthroscopy to address intra-articular injuries and reduction and osteosynthesis of the fracture.
  
  
  RESULTS
  A high incidence of intra-articular injuries was noticed, and 76.6% of them presented injury of the triangular fibrocartilage complex, 36.6% of the intrinsic scapholunate ligament, 6.6% of the intrinsic triquetrolunate ligament, and 33% articular cartilage injury larger than three millimeters. Patients with fractures from type C according to AO/ASIF classification presented a higher incidence of ligament injuries.
  
  
  CONCLUSIONS
  There is no relationship between the presence of chondral injury and the AO/ASIF classification of the fractures in the cases reported in this study.
