Abstract
PROBLEM: In revision alloarthroplasty the need for bone allografts increased. The documentation of the defects is not done routinely. METHOD: For better documentation the German Society for Orthopedics and Traumatology (DGOT) developed a new and practical defect classification system. It was tested clinically in the last 6 years. RESULTS: In the acetabulum and femoral shaft seven defect types were distinguished and presented in figures. For the acetabulum: 1 cavitary holes, 2-4 unisegmental, 5 bisegmental, 6 trisegmental, 7 pelvic instability. For the femur: 1 intramedullary 2 trochanter 3 calcar 4 med. shaft 5 lat. shaft 6 part. diaphysis 7 total diaphysis. CONCLUSION: With this classification system we could better compared different reconstruction approaches in endoprosthetic surgery.
