This 2-part model is a natural cast of a male, bone pelvis. It shows all anatomical structures in detail: both hip bones, pubic symphisis, sacrum and coccyx as well as the fifth lumbar vertebra with intervertebral disc. A median section has been placed through the fifth lumbar vertebra, the sacrum and the coccyx, so that the pelvis, which is connected by practical magnets, can be split easily into two halves. This means that part of the cauda equina is also visible in the vertebral canal. The model shows the following pelvis ligaments: Lig. inguinale, Lig. sacrotuberale, Lig. sacrospinale, Ligg. sacroiliaca anteriora, Lig. iliolumbale, Lig. longitudinale anterius, Lig. Supraspinale, Lig. sacroiliacum interosseum, Lig. sacroiliacum posterius, Lig. sacrococcygeum laterale, Lig. sacrococcygeum posterius superficiale et profundum, Membrana obturatoria und Lig. lacunare.
