An anatomical study was undertaken using cadaveric forearms to identify the best technique and angle of pin placement for external fixator pins. We have found that inserting pins through stab incisions risks transfixion of the underlying structures and leads to an increased morbidity. We conclude that inserting pins under direct vision is much safer and that the optimum angle of pin insertion is in the coronal plane, parallel to the plane of the metacarpals.
采用尸体前臂进行解剖学研究，以确定外固定针的最佳置入技术和角度。我们发现，通过小切口插入钢针有穿透下方结构的风险，并会增加发病率。我们得出结论，在直视下插入钢针要安全得多，并且钢针插入的最佳角度是在冠状面，与掌骨平面平行。
