Ulnohumeral Arthroplasty (distraction interpositon)
  • Introduction
    • resection followed by contouring of articular surfaces with fascia coverage
    • some use distraction external fixator to allow early motion
  • Indications

    • joint space narrowing
    • osteophytes (especially in posteromedial olecranon)
  • Limitations
    • incomplete anterior release
