The aim of this study is to describe the number and location of the nutrient foramina in human scapulae which can minimize blood loss during surgery.
30 cadaveric scapulae were macerated to denude the skeletal tissue. The nutrient foramina of 0.51 mm and larger were identified and labeled by adhering glass beads. CT scans of these scapulae were segmented resulting in a surface model of each scapula and the location of the labeled nutrient foramina. All scapulae were scaled to the same size projecting the nutrient foramina onto one representative scapular model.
Average number of nutrient foramina per scapula was 5.3 (0-10). The most common location was in the supraspinous fossa (29.7%). On the costal surface of the scapula, most nutrient foramina were found directly inferior to the suprascapular notch. On the posterior surface, the nutrient foramina were identified under the spine of the scapula in a somewhat similar fashion as those on the costal surface. Nutrient foramina were least present in the peri-glenoid area.
Ninety percent of scapulae have more than one nutrient foramen. They are located in specific areas, on both the posterior and costal surface.
本研究旨在描述人肩胛骨中的营养孔的数量和位置，以最大限度地减少手术中的失血。
将 30 具尸体肩胛骨进行浸软处理，以去除骨骼组织。将直径为 0.51 毫米及以上的营养孔识别出来，并贴上玻璃珠进行标记。对这些肩胛骨进行 CT 扫描，对每个肩胛骨进行表面建模，并对标记的营养孔的位置进行分割。所有肩胛骨都按相同的比例缩放，将营养孔投影到一个有代表性的肩胛骨模型上。
平均每块肩胛骨有 5.3 个（0-10 个）营养孔。最常见的位置是在棘上窝（29.7%）。在肩胛骨的肋面，大多数营养孔位于肩胛上切迹的直接下方。在后面，营养孔在肩胛骨的脊柱下被识别出来，其位置与肋面的类似。营养孔在关节盂周围区域最少。
90%的肩胛骨有不止一个营养孔。它们位于特定的区域，包括后面和肋面。
