The humerus bone with coronoid-olecranon septal aperture have very narrow medullary canal and extreme anterolateral bowing proximally and/or extreme anterolateral compressed surface at distal part. Septal perforation might make nailing through a retrograde technique more difficult or possibly with an increased risk of iatrogenic fracture at the site of insertion. Coronoid-olecranon perforation might be very important in preoperative planning for successful nailing. Since the data available has been obtained from the ancient studies using the skeletal material, the present study is aimed at investigating originally the presence of the coronoid-olecranon septum perforation in the living subjects, using a radiographic method.
The study was performed on direct radiograms and computed tomography of the elbow obtained from the 709 volunteers (367 males, 342 females).
The incidence of the perforation was found to be 8.6 %. Bilateral occurrence was found to be more common significantly. The highest incidence occurred in second decade.
The present study suggests female prepronounced and left asymmetry in case of septal perforation. Bilateral occurrence from our study might be peculiar to the clinician.
存在冠状突-鹰嘴间隔孔的肱骨，其髓腔非常狭窄，近端有极明显的前外侧弓形弯曲和/或远端有极明显的前外侧压缩面。间隔穿孔可能会使逆行穿钉技术更困难，或者可能增加插入部位医源性骨折的风险。冠状突-鹰嘴穿孔在成功穿钉的术前规划中可能非常重要。由于现有数据是从使用骨骼材料的古代研究中获得的，本研究旨在使用放射学方法，首次调查活体中冠状突-鹰嘴间隔穿孔的情况。
对709名志愿者（367名男性，342名女性）的肘部直接X线片和计算机断层扫描进行研究。
发现穿孔发生率为8.6%。双侧发生明显更为常见。最高发生率出现在第二个十年。
本研究表明间隔穿孔情况下女性更为明显且存在左侧不对称。我们研究中的双侧发生情况可能是临床医生所特有的。
