The treatment of olecranon fractures frequently involves the use of tension-band fixation. Although associated with high union rates, this method has a high incidence of morbidity associated with soft tissue compromise and limitation of range of movement requiring frequent re-operation for removal of metal. We describe the use of a simple jig to ensure intramedullary placement of longitudinal K-wires and compare the accuracy of placement of Kirschner (K)-wires using this device with the traditional free-hand method. We found the distance from the centre of the medullary canal, the range and standard deviations of K-wire positions to be significantly more precise when the jig was used. This has applications for the use of the device, both with standard metallic radio-opaque wires and potentially with bio-absorbable pins.
尺骨鹰嘴骨折的治疗常涉及张力带固定。虽然该方法与高愈合率相关，但它也与软组织损伤和活动范围受限相关的发病率较高有关，需要经常进行金属移除的再次手术。我们描述了使用简单的夹具来确保髓内纵向 K 线的放置，并比较了使用该装置与传统徒手方法放置克氏针（K）的准确性。我们发现，使用夹具时，从髓腔中心的距离、K 线位置的范围和标准偏差都明显更精确。该装置可应用于标准金属不透射线线和潜在的可吸收钉的使用。
