在这项研究中，从25具防腐尸体的44个髋关节区域进行了解剖，以确定大转子上的骨性标志，这表明了个体的短外旋肌止点。获得微型计算机断层扫描（micro-CT）图像，以识别大转子上的骨性压痕。然后，切除软组织并识别其插入以评估与显微CT图像的相关性。在所有标本的大转子上识别出表示梨状肌、闭孔内肌和闭孔外肌的插入和运行过程的骨性标志。这些发现可能有助于在前路关节囊松解过程中保留肌肉，因为术前可以使用CT图像估计短外旋肌的排列。(c)2014爱思唯尔公司All rights reserved.
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.
