title: [Semiconstrained bipolar implant arthroplasty of the distal radioulnar joint. Case report].
abstract: BACKGROUND
  The distal radioulnar joint is of paramount importance for the proper function of the upper extremity. There is a wide variety of procedures for the treatment of its advanced pathology but none of them is capable of providing a stable load-bearing joint.
  
  
  METHODS
  We present the case of a 54 year old man who was treated by a semiconstrained bipolar distal radioulnar joint arthroplasty (Aptis) who had a distal radioulnar impingement secondary to a distal ulnar resection (Darrach) previously performed to treat a fracture-dislocation of the distal radioulnar joint.
  
  
  CONCLUSIONS
  This case was the first semiconstrained bipolar distal radioulnar joint arthroplasty (Aptis) performed in México. This treatment is capable of providing provides a stable load-bearing joint.
