The aim of our study is to study the prevalence and anatomy of scapular foramina (SF) and scapular nutrient foramina (SNF) in dried skeletons from the Northeastern Thai population.
A total of 150 dried scapulae were investigated. Both SF and SNF were identified using a metal wire with a diameter of 0.36 mm. The number, locations, lengths, and diameters of SF were recorded. Subsequently, SNF were identified using the same metal wire. Their number and locations were recorded. Two observers performed the evaluations and measurements.
SF were present in 78.0% of scapulae. They could have up to five openings. Eighteen types were found. On average they were longer in males (21.7 ± 5.0 mm) than females (19.45 ± 4.6 mm). The mean diameters of both the superior and inferior openings were significantly greater in females (p < 0.01). SNF, in contrast, were present in 100% of scapulae. They were located in the supraspinous fossa (36.7%), subscapular fossa (31.3%), infraspinous fossa (22.8%), and peri-glenoid area (10.0%).
Unlike previous studies, the present study suggests that SF are normal anatomical findings, present in 78.0% of the scapulae investigated. Surgeons should be aware of both SNF and SF when operating or interpreting radiological findings.
我们研究的目的是调查泰国东北部人群干燥骨骼中肩胛孔（SF）和肩胛滋养孔（SNF）的发生率及解剖结构。
共研究了150具干燥肩胛骨。使用直径0.36毫米的金属丝来识别SF和SNF。记录SF的数量、位置、长度和直径。随后，用同一根金属丝识别SNF。记录其数量和位置。由两名观察者进行评估和测量。
78.0%的肩胛骨存在SF。SF最多可有五个开口。共发现18种类型。平均而言，男性的SF（21.7±5.0毫米）比女性的（19.45±4.6毫米）更长。女性SF上下开口的平均直径均显著更大（p<0.01）。相比之下，100%的肩胛骨存在SNF。它们位于冈上窝（36.7%）、肩胛下窝（31.3%）、冈下窝（22.8%）和关节盂周围区域（10.0%）。
与先前研究不同，本研究表明SF是正常的解剖学发现，在所研究的78.0%的肩胛骨中存在。外科医生在手术或解读影像学检查结果时应注意SNF和SF。
