Pelvic fracture fixation methods: first, in the acute stage can be used a pocket, in the hospital will have the mesh pocket, from the back of the hip, from both sides to the top fixed in the bed frame above the bar, so that the pocket up to the ring around is the simplest way of external fixation. Secondly, 2-3 thick screws are fixed in the position of iliac crest, and then the screws are bolted with a cross bar and a long iron bar, so as to form a ring-like fixation, and the pelvis is fixed with external fixation instruments, nails and rods. Thirdly, bone traction can be done, such as acetabular comminuted fracture can be femoral traction, the femur is the thigh hold, this time the pelvis can not move. This is a few external fixation methods, and then there is internal fixation methods, mainly reconstruction plate, can be shaped reconstruction plate, and screws, hollow screws, sacroiliac screws, sacroiliac screws is to fix the joints of the sacrum and the ilium, general hollow screws may be fixed iliac wing, that is, the pelvic ring, and fixed with displaced fracture with steel plate and screws.
