An 22 frisch entnommenen Leichenbecken wurden die Ileosacralge- lenke isoliert in einer speziellen Halterung einer statischen Zugbelastung unterworfen. 39 Ileosacralgelenke wurden ausgewertet. In transversaler Richtung kam es in 10 von 12 Gelenken zu Band- rupturen bei 3320 + 938 N und zu 2 Frakturen bei 2892 + 1318 N. Bei ventro-cranialer Zugbelastung wurde das Gelenk abgeschert (8 Bandausrisse 4508 + 1187 N, 9 Frakturen 3316 + 482 N). Die dorso- craniale Zugbelastung ergab die hochsten Kraftwerte (6 Bandr- se 5150 + 946 N, 4 Frakturen 5653 + 940 N). Diese Zugrichtung entspricht annahernd der Belastungsrichtung beim Stehen. Summary Experiments were carried out on 22 human cadaver pelves. The iso- lated sacroiliac joints were subjected to static traction in three dimensions (transversal, ventrocranial, dorsocranial) in a special holding device. The ileum was pulled away from the sacrum in each case. In all,39 joints were evaluated. The transverse traction tested the tightness of the ligamentous fibers only: 10 of 12 joints ruptured with an average force of 3320 + 938 N, while in 2 cases fracture of the sacrum occurred with 2892 + 1318 N. The ventrocranial traction force was much higher. It generated rupture in 8 cases (4508 + 1187 N) and in 9 cases, fracture (3316 + 482 N). The dorsocranial traction simulated the weight- bearing situation in standing (6 ruptures with 5150 + 946 Nand 4 fractures with 5653 + 940 N). Literatur 1.
