In this study, 44 hip regions from 25 embalmed cadavers were dissected to identify the bony landmarks on the greater trochanter, which indicate the individual short external rotator muscle insertions. Micro-computed tomography (micro-CT) images were obtained to identify the bony impressions on the greater trochanter. Then, the soft tissues were removed and their insertions were identified to assess correlation with micro-CT images. Bony landmarks indicating the insertions and the running course of the piriformis muscle, the obturator internus muscle, and the obturator externus muscle were identified on the greater trochanter in all specimens. These findings could be helpful for preserving muscles during capsular release in the anterior approach because the alignment of the short external rotator muscles can be estimated preoperatively using CT images.
在这项研究中，对 25 具防腐尸体的 44 个髋区进行了解剖，以确定大转子上的骨性标志，这些标志指示了个体短外旋肌的附着点。获取微计算机断层扫描（micro-CT）图像以识别大转子上的骨性痕迹。然后，去除软组织并确定其附着点，以评估与 micro-CT 图像的相关性。在所有标本的大转子上均确定了指示附着点和梨状肌、闭孔内肌和闭孔外肌走行的骨性标志。这些发现可能有助于在前路关节囊松解术中保留肌肉，因为可以使用 CT 图像在术前估计短外旋肌的对齐情况。
