Objective: pelvic fracture injury, the incidence of a high-energy second only to the limbs and spine fractures . While medical technology has greatly improved, and its morbidity , mortality rates were higher than the non - pelvic fracture . Open book type fracture of the pubic symphysis separation greater than 25 mm and hemodynamic instability should take urgent external fixation stable hemodynamic fight for the opportunity for further treatment to save the patient life . First aid often fixed pelvic external fixator , but external fixation direction , at home and abroad , there is no unified conclusion . The subject of the treatment of open- book type fracture common external fixation direction biomechanical comparison provides a theoretical basis for clinical choose the best fixed direction . By setting the control group and the experimental group , the clinical comparison , explore its efficacy and the incidence of complications , and to provide new ideas and methods for the clinical . Method: an open book fracture pelvic external fixation biomechanics five recent anti-corrosion adult cadavers , four men and one women , aged 40 to 60 years old , 51 years old on average . Since the fifth lumbar vertebra and femur in the previous paragraph is truncated to get the complete pelvis 5 and connected the proximal 1 / 3 of the femur specimens . By visual observation and X-ray , CT scan confirmed no significant osteoporosis and tuberculosis, cancer and other diseases of the skeletal system . Removal of soft tissue and muscle , retained sacrotuberous ligaments and sacral spine ligament complete , carefully remove the top of the fifth lumbar disc tissue , exposed bone , and deployment of a good denture base resin is a weight-bearing cast in the fifth lumbar platform , so the platform standing neutral position
