Potential secular changes in the human scapula are fundamentally unbeknownst, with most of the preceding anatomical studies focusing on long-term changes in the long bones and the skull. As such, the cardinal purpose of this study pertains to the evaluation of secular trends on the shape and size of the scapula in a time period spanning from the 19th to the early 21st centuries. The study sample included 211 individuals (100 males and 111 females) from the Coimbra Identified Skeletal Collection and the 21st Century Identified Skeletal Collection. The size and shape of the scapula were evaluated using geometric morphometrics. Results show secular changes over a relatively short period of time in both the shape and size of the scapula in Portuguese nationals. Shape changes were observed in both sexes but expressed minimally, while a significant negative trend in the size of the scapula was detected in males. Scapular size decrement in males conceivably echoes general trends of the overall anatomy towards a narrower body associated with higher standards of living that include enhanced nutrition and universal healthcare, among other factors.
人类肩胛骨潜在的长期变化基本上不为人知，之前的大多数解剖学研究都集中在长骨和颅骨的长期变化上。因此，本研究的主要目的是评估19世纪至21世纪期间肩胛骨形状和大小的长期趋势。研究样本包括来自科英布拉已识别骨骼收藏和21世纪已识别骨骼收藏的211个人（100名男性和111名女性）。使用几何形态计量学评估肩胛骨的大小和形状。结果显示，葡萄牙国民的肩胛骨形状和大小在相对较短的时间内出现了长期变化。两性均观察到形状变化，但表现轻微，而男性肩胛骨大小出现显著负趋势。男性肩胛骨尺寸减小可能反映了整体解剖结构朝着与更高生活水平相关的更窄身体的总体趋势，这些生活水平包括营养改善和全民医疗保健等因素。
