To improve the accuracy of pinning at the iliac crest during external fixation of the pelvic fracture, an aiming device has been designed. The device consists of 3 parts: a sleeve which accommodates a 5.0 Shanz pin, a handle and guide points. The guide points were designed to grasp the iliac crest to allow proper pin fixation. The device has undergone trials to fix Shanz pins on the iliac crests of 10 cadavers by 10 recently graduated doctors. All pins were fixed in proper position and passed into the bone between the two tables of the iliac crest without penetrating the tables. The device has so far been used in 50 patients who had unstable pelvic fractures. All pins were in the proper positions and there had been no loosening at the time the pins were removed. The use of this aiming device for pinning the iliac crest for external fixation of pelvic fracture has given encouraging results.
为提高骨盆骨折外固定时髂嵴穿针的准确性，设计了一种瞄准装置。该装置由三部分组成：一个容纳5.0 mm斯氏针的套筒、一个手柄和导向点。导向点设计用于抓住髂嵴，以便正确地固定钢针。该装置已由10名刚毕业的医生在10具尸体的髂嵴上进行了斯氏针固定试验。所有钢针均固定在正确位置，并穿过髂嵴两层骨板之间的骨质，未穿透骨板。到目前为止，该装置已用于50例不稳定骨盆骨折患者。所有钢针位置均正确，拔除钢针时未出现松动。使用这种瞄准装置进行髂嵴穿针以用于骨盆骨折的外固定，已取得了令人鼓舞的结果。
