Early external fixation of major pelvic fractures reduces haemorrhage and mortality. The best site and method for pin placement remains unresolved. The superior iliac crest is biomechanically disadvantageous and hinders access to the abdomen. Low pin placement between the anterior iliac spines has been proposed as a better solution. A case-controlled study was performed on cadavers using a jig designed to place external fixator pins accurately in the pelvis; the study tested the safety of pin placement and the mechanical strength of the two placement sites. The results showed that pins could be placed safely using this method and that low placement in cadaveric bone is as strong as that of the conventional placement.
早期对严重骨盆骨折进行外固定可减少出血和死亡率。针钉置入的最佳部位和方法仍未确定。髂嵴上方在生物力学上存在劣势，且妨碍进入腹部。有人提出在前髂棘之间较低位置置入针钉是更好的解决方案。使用一种设计用于在骨盆中精确置入外固定器针钉的夹具对尸体进行了病例对照研究；该研究测试了针钉置入的安全性以及两个置入部位的机械强度。结果表明，使用这种方法可以安全地置入针钉，并且在尸体骨中较低位置置入的强度与传统置入方式相同。
