We have developed a drill-hole guide valuable in accurately positioning the fracture of the mandibular ramus. It operates by introducing a Kirschner wire through the fracture stump from the mandibular angle to the condyle. A 2.0- to 2.4-mm-diameter Kirschner wire is drilled into the ramus from below and proceeds up to the condylar fragment through the stump of the fracture. With this guide, 15 patients with 23 subcondylar fractures underwent open reduction with Kirschner wire fixation. In each case, wire, by means of a pinning technique, was inserted accurately from the mandibular angle to the repositioned condyle.
我们开发了一种钻孔导向器，对准确确定下颌支骨折的位置很有价值。它的操作方法是将一根克氏针从下颌角穿过骨折残端插入到髁突。将直径2.0至2.4毫米的克氏针从下方钻入下颌支，并通过骨折残端向上穿至髁突骨折块。使用该导向器，15例共23处髁突下骨折患者接受了克氏针内固定切开复位术。在每例手术中，通过穿针技术将克氏针从下颌角准确插入到复位后的髁突。
