Secure fixation by inserting a half-pin into the iliac crest as a pelvic external fixator is important. However, the thickness of the iliac bone depends on its location and this makes it difficult to insert a half-pin accurately. The iliac crest is especially narrow in the paediatric pelvis, making it difficult to insert the half-pin accurately compared with an adult pelvis. A case of pelvic external fixation is described for a paediatric pelvic fracture in this report, in which preoperative planning for half-pin insertion was performed accurately using a preoperative three-dimensional CT based on an intraoperative support device that uses the functional pelvic plane as a reference.
使用半针将髂嵴插入作为骨盆外固定器进行固定非常重要。然而，髂骨的厚度取决于其位置，这使得准确插入半针变得困难。在小儿骨盆中，髂嵴特别狭窄，与成人骨盆相比，准确插入半针更加困难。本报告介绍了一例小儿骨盆骨折的骨盆外固定病例，术中使用功能骨盆平面作为参考的术中支撑装置，术前根据术前三维 CT 对插入半针进行了准确的术前规划。
